kn-title=The required experience of open pancreaticoduodenectomy before becoming a specialist in hepatobiliary and pancreatic surgeons: a multicenter, cohort study of 334 open pancreaticoduodenectomies
en-subtitle=

en-abstract=
kn-abstract=Background Open pancreaticoduodenectomy (OPD) is an essential surgical procedure for expert hepato-biliary-pancreatic (HBP) surgeons. However, there is no standard for how many surgeries must be performed by a surgeon in training before they are considered to have enough experience to ensure surgical safety. <br>
Methods Cumulative Sum (CUSUM) analysis was performed using the surgical data of OPDs performed during the training period of board-certified expert surgeons of the Japanese Society of Hepato-Biliary-Pancreatic Surgery. <br>
Results Fourteen HBP surgeons participated in this study and performed 334 OPDs during their training period. The median (interquartile range) values for operative time, blood loss, and length of hospital stay were 455 (397-519) minutes, 450 (234--716) ml, and 28 (21-38) days, respectively. CUSUM analysis showed inflection points at 20 surgeries performed for operative time. After 20 procedures, operative time was significantly shorter (461 min vs. 425 min, p = 0.021) and blood loss was significantly lower (470 ml vs. 340 ml, p = 0.038). No significant differences between within 20 and after 21 procedures were found in the complication rate (53% vs. 48%, p = 0.424) and rate of in-hospital deaths (1.5% vs.1.4%. p = 0.945). Up to 20 surgeries, PDAC and another malignant tumor had longer operative time than benign/low malignant diseases (486 min vs. 472 min vs. 429 min, p < 0.001), and higher blood loss (500 ml vs. 502 ml vs. 355 ml, p < 0.001). Mortality rate was higher at PDAC cases (5% vs. 0% vs. 0%, p = 0.01). After the 21 procedures, these outcomes were improved and no differences in by primary disease were observed. Multivariable analysis showed that within 20 surgeries were independent risk factors of longer operative time (HR2.6, p = 0.013) and higher blood loss (HR2.0, p = 0.049). <br>
Conclusions To stabilize the surgical outcome of OPD for malignant disease, at least 20 surgeries should be performed at a certified institution during surgeon training. Trial registrationClinical trial number: Not applicable.

kn-title=Innovative suture technique for robotic hepaticojejunostomy: double-layer interrupted sutures
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Purpose Biliary reconstruction remains a technically demanding and complicated procedure in minimally invasive hepatopancreatobiliary surgeries. No optimal hepaticojejunostomy (HJ) technique has been demonstrated to be superior for preventing biliary complications. This study aimed to investigate the feasibility of our unique technique of posterior double-layer interrupted sutures in robotic HJ.<br>
Methods We performed a retrospective analysis of a prospectively collected database. Forty-two patients who underwent robotic pancreatoduodenectomy using this technique between September 2020 and November 2022 at our center were reviewed. In the posterior double-layer interrupted technique, sutures were placed to bite the bile duct, posterior seromuscular layer of the jejunum, and full thickness of the jejunum.<br>
Results The median operative time was 410 (interquartile range [IQR], 388–478) min, and the median HJ time was 30 (IQR, 28–39) min. The median bile duct diameter was 7 (IQR, 6–10) mm. Of the 42 patients, one patient (2.4%) had grade B bile leakage. During the median follow-up of 12.6 months, one patient (2.4%) with bile leakage developed anastomotic stenosis. Perioperative mortality was not observed. A surgical video showing the posterior double-layer interrupted sutures in the robotic HJ is included.<br>
Conclusions Posterior double-layer interrupted sutures in robotic HJ provided a simple and feasible method for biliary reconstruction with a low risk of biliary complications.

kn-title=Impact of educational video on performance in robotic simulation training (TAKUMI-1): a randomized controlled trial
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The use of virtual reality for simulations plays an important role in the initial training for robotic surgery. This randomized controlled trial aimed to investigate the impact of educational video on the performance of robotic simulation. Participants were randomized into the intervention (video) group that received an educational video and robotic simulation training or the control group that received only simulation training. The da Vinci® Skills Simulator was used for the basic course, including nine drills. The primary endpoint was the overall score of nine drills in cycles 1–10. Secondary endpoints included overall, efficiency, and penalty scores in each cycle, as well as the learning curves evaluated by the cumulative sum (CUSUM) analysis. Between September 2021 and May 2022, 20 participants were assigned to the video (n = 10) and control (n = 10) groups. The video group had significantly higher overall scores than the control group (90.8 vs. 72.4, P < 0.001). Significantly higher overall scores and lower penalty scores were confirmed, mainly in cycles 1–5. CUSUM analysis revealed a shorter learning curve in the video group. The present study demonstrated that educational video training can be effective in improving the performance of robotic simulation training and shortening the learning curve.

kn-title=Epidural versus patient-controlled intravenous analgesia on pain relief and recovery after laparoscopic gastrectomy for gastric cancer: randomized clinical trial
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background: Epidural analgesia (EDA) is a main modality for postoperative pain relief in major open abdominal surgery within the Enhanced Recovery After Surgery protocol. However, it remains unclear whether EDA is an imperative modality in laparoscopic gastrectomy (LG). This study examined non-inferiority of patient-controlled intravenous analgesia (PCIA) to EDA in terms of postoperative pain and recovery in patients who underwent LG. <br>
Methods: In this open-label, non-inferiority, parallel, individually randomized clinical trial, patients who underwent elective LG for gastric cancer were randomized 1:1 to receive either EDA or PCIA after surgery. The primary endpoint was pain score using the Numerical Rating Scale at rest 24 h after surgery, analysed both according to the intention-to-treat (ITT) principle and per protocol. The non-inferiority margin for pain score was set at 1. Secondary outcomes were postoperative parameters related to recovery and adverse events related to analgesia. <br>
Results: Between 3 July 2017 and 29 September 2020, 132 patients were randomized to receive either EDA (n = 66) or PCIA (n = 66). After exclusions, 64 patients were included in the EDA group and 65 patients in the PCIA group for the ITT analysis. Pain score at rest 24 h after surgery was 1.94 (s.d. 2.07) in the EDA group and 2.63 (s.d. 1.76) in the PCIA group (P = 0.043). PCIA was not non-inferior to EDA for the primary endpoint (difference 0.69, one side 95% c.i. 1.25, P = 0.184) in ITT analysis. Postoperative parameters related to recovery were similar between groups. More EDA patients (21 (32.8%) versus 1 (1.5%), P < 0.001) developed postoperative hypotension as an adverse event.<br>
Conclusions: PCIA was not non-inferior to EDA in terms of early-phase pain relief after LG. Registration number: UMIN000027643 (https://www.umin.ac.jp/ctr/index-j.htm). Conclusions: PCIA was not non-inferior to EDA in terms of early-phase pain relief after LG.Registration number: UMIN000027643 (https://www.umin.ac.jp/ctr/index-j.htm).

kn-title=Robotic surgery for congenital biliary dilatation using the scope switch technique (with video)
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Technique: Minimally invasive congenital biliary dilatation (CBD) surgery is technically demanding. However, few studies have reported surgical approaches of robotic surgery for CBD. This report presents robotic CBD surgery using a scope-switch technique. Our robotic surgery technique for CBD consisted of four steps: step 1, Kocher's maneuver; step 2, dissection of the hepatoduodenal ligament using the scope switch technique; step 3, preparation for the Roux-en-Y loop; and step 4, hepaticojejunostomy. <br>
Results: The scope switch technique can provide different surgical approaches for dissecting the bile duct, including anterior approach by the standard position and right approach by the scope switch position. When approaching the ventral and left side of the bile duct, anterior approach with the standard position is suitable. In contrast, the lateral view by the scope switch position is preferable for approaching the bile duct laterally and dorsally. Using this technique, the dilated bile duct can be dissected circumferentially from four directions: anterior, medial, lateral, and posterior. Thereafter, complete resection of the choledochal cyst can be achieved. <br>
Conclusions: The scope switch technique in robotic surgery for CBD can be useful for dissecting around the bile duct with different surgical views, leading to the complete resection of the choledochal cyst.

kn-title=Diagnostic Utility of the PD-L1 Immunostaining in Biopsy Specimens of Patients with Biliary Tract Neoplasms
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background　Anti-programmed death 1/programmed death ligand 1 (PD1/PD-L1) antibodies have been successfully used as treatment agents for several solid tumors; however, it is difficult to predict their effectiveness. We evaluated whether biopsy specimens could predict the positive status of PD-L1 in surgically resected tissue.<br>
Methods　Among 91 patients who underwent tissue sampling with endoscopic or liver biopsy before surgery for biliary tract neoplasms in an academic center, 45 (49%) patients were selected for retrospective analysis because the quality and quantity of their biopsy specimens were adequate for histologic evaluation. We performed immunohistochemical staining to investigate the PD-L1 expression in both resected and biopsy specimens. The percentage of the positively stained cells was calculated for subsequent use in the correlation investigation.<br>
Results　The biopsy methods were endoscopic retrograde cholangiopancreatography (ERCP) in 28 cases, percutaneous liver biopsy in 10 cases, and endoscopic ultrasound fine-needle aspiration in 7 cases. Among the 45 patients, when patients with > 10% positive tumor cells in surgically resected tissues were regarded as truly positive PD-L1, the positive and negative concordance rates between surgically resected tissues and biopsy samples were 56% (5/9) and 100% (36/36), respectively. With regard to the use of preoperative biopsy as a diagnostic tool, all (5/5) PD-L1-positive patients had a positive resected specimen. The accuracy of each biopsy method was as follows: ERCP, 89% (25/28); fine-needle aspiration, 86% (6/7); and liver biopsy, 100% (10/10).<br>
Conclusions　Biopsy samples could be a surrogate material for the assessment of the PD-L1 expression with substantial positive and high negative concordance rates.

kn-title=Dual antiplatelet therapy inhibits neutrophil extracellular traps to reduce liver micrometastases of intrahepatic cholangiocarcinoma
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The involvement of neutrophil extracellular traps (NETs) in cancer metastasis is being clarified, but the relationship between intrahepatic cholangiocarcinoma (iCCA) and NETs remains unclear. The presence of NETs was verified by multiple fluorescence staining in clinically resected specimens of iCCA. Human neutrophils were co-cultured with iCCA cells to observe NET induction and changes in cellular characteristics. Binding of platelets to iCCA cells and its mechanism were also examined, and their effects on NETs were analyzed in vitro and in in vivo mouse models. NETs were present in the tumor periphery of resected iCCAs. NETs promoted the motility and migration ability of iCCA cells in vitro. Although iCCA cells alone had a weak NET-inducing ability, the binding of platelets to iCCA cells via P-selectin promoted NET induction. Based on these results, antiplatelet drugs were applied to these cocultures in vitro and inhibited the binding of platelets to iCCA cells and the induction of NETs. Fluorescently labeled iCCA cells were injected into the spleen of mice, resulting in the formation of liver micrometastases coexisting with platelets and NETs. These mice were treated with dual antiplatelet therapy (DAPT) consisting of aspirin and ticagrelor, which dramatically reduced micrometastases. These results suggest that potent antiplatelet therapy prevents micrometastases of iCCA cells by inhibiting platelet activation and NET production, and it may contribute to a novel therapeutic strategy.

kn-title=Impact of cancer-associated fibroblasts on survival of patients with ampullary carcinoma
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background: Cancer-associated fibroblasts (CAFs) reportedly enhance the progression of gastrointestinal surgery; however, the role of CAFs in ampullary carcinomas remains poorly examined. This study aimed to investigate the effect of CAFs on the survival of patients with ampullary carcinoma. <br>
Materials and methods: A retrospective analysis of 67 patients who underwent pancreatoduodenectomy between January 2000 and December 2021 was performed. CAFs were defined as spindle-shaped cells that expressed alpha-smooth muscle actin (alpha-SMA) and fibroblast activation protein (FAP). The impact of CAFs on survival, including recurrence-free (RFS) and disease-specific survival (DSS), as well as prognostic factors associated with survival, was analyzed. <br>
Results: The high-alpha-SMA group had significantly worse 5-year RFS (47.6% vs. 82.2%, p = 0.003) and 5-year DSS (67.5% vs. 93.3%, p = 0.01) than the low-alpha-SMA group. RFS (p = 0.04) and DSS (p = 0.02) in the high-FAP group were significantly worse than those in the low-FAP group. Multivariable analyses found that high alpha-SMA expression was an independent predictor of RFS [hazard ratio (HR): 3.68; 95% confidence intervals (CI): 1.21-12.4; p = 0.02] and DSS (HR: 8.54; 95% CI: 1.21-170; p = 0.03). <br>
Conclusions: CAFs, particularly alpha-SMA, can be useful predictors of survival in patients undergoing radical resection for ampullary carcinomas.

kn-title=Role of the Pfannenstiel Incision in Robotic Hepato-Pancreato-Biliary Surgery
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Studies remain limited on the role of the Pfannenstiel incision in minimally invasive hepato-pancreato-biliary (HPB) surgery, especially robotic surgery. The role of various extraction sites in robotic HPB surgery should be understood. Herein, we describe the surgical techniques, outcomes, advantages, and disadvantages of the Pfannenstiel incision in robotic pancreatic surgery. Seventy patients underwent robotic pancreatectomy at our institution between September 2020 and October 2022. The Pfannenstiel incision was used for specimen retrieval in 55 patients. Advantages of the Pfannenstiel incision include less pain, cosmetic benefits, and a lower incidence of complications. Moreover, the specimen could be removed using the robotic system docked. However, all complex reconstructions should be performed intra-abdominally during robotic pancreatoduodenectomies. The incidence of mortality and postoperative pancreatic fistula (grade B) was 0% and 9.1%, respectively. During the median follow-up (11.2 months) after surgery, complications at the Pfannenstiel incision site included surgical site infection (n = 1, 1.8%) and incisional hernia (n = 1, 1.8%). The Pfannenstiel incision can be a useful option for specimen retrieval in minimally invasive HPB surgery, according to the surgeon's preferences and the patient's condition.

kn-title=Surgical Techniques of Gastrojejunostomy in Robotic Pancreatoduodenectomy: Robot-Sewn versus Stapled Gastrojejunostomy Anastomosis
en-subtitle=

kn-abstract=Background: Delayed gastric emptying (DGE) is a major complication of pancreatoduodenectomy (PD). Several efforts have been made to decrease the incidence of DGE. However, the optimal anastomotic method for gastro/duodenojejunostomy (GJ) remains debatable. Moreover, few studies have reported the impact of GJ surgical techniques on outcomes following robotic pancreatoduodenectomy (RPD). This study aimed to investigate the surgical outcomes of robot-sewn and stapled GJ anastomoses in RPD. Methods: Forty patients who underwent RPD at the Okayama University Hospital between September 2020 and October 2022 were included. The outcomes between robot-sewn and stapled anastomoses were compared. Results: The mean [standard deviation (SD)] operative and GJ time were 428 (63.5) and 34.0 (15.0) minutes, respectively. Postoperative outcomes included an overall incidence of DGE of 15.0%, and the mean postoperative hospital stays were 11.6 (5.3) days in length. The stapled group (n = 21) had significantly shorter GJ time than the robot-sewn group (n = 19) (22.7 min versus 46.5 min, p < 0.001). Moreover, stapled GJ cases were significantly associated with a lower incidence of DGE (0% versus 21%, p = 0.01). Although not significant, the stapled group tended to have shorter postoperative hospital stays (9.9 days versus 13.5 days, p = 0.08). Conclusions: Our findings suggest that stapled GJ anastomosis might decrease anastomotic GJ time and incidence of DGE after RPD. Surgeons should select a suitable method for GJ anastomosis based on their experiences with RPD.

kn-title=Surgical Strategies to Dissect around the Superior Mesenteric Artery in Robotic Pancreatoduodenectomy
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The concept of the superior mesenteric artery (SMA)-first approach has been widely accepted in pancreatoduodenectomy. However, few studies have reported surgical approaches to the SMA in robotic pancreatoduodenectomy (RPD). Herein, we present our surgical strategies to dissect around the SMA in RPD. Among the various approaches, our standard protocol for RPD included the right approach to the SMA, which can result in complete tumor resection in most cases. In patients with malignant diseases requiring lymphadenectomy around the SMA, we developed a novel approach by combining the left and right approaches in RPD. Using this approach, circumferential dissection around the SMA can be achieved through both the left and right sides. This approach can also be helpful in patients with obesity or intra-abdominal adhesions. The present study summarizes the advantages and disadvantages of both the approaches during RPD. To perform RPD safely, surgeons should understand the different surgical approaches and select the best approach or a combination of different approaches, depending on demographic, anatomical, and oncological factors.

kn-title=Clinical implications and optimal extent of lymphadenectomy for intrahepatic cholangiocarcinoma: A multicenter analysis of the therapeutic index
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Aims Lymph node metastases (LNM) are associated with lethal prognosis in intrahepatic cholangiocarcinoma (ICC). Lymphadenectomy is crucial for accurate staging and hopes of possible oncological treatment. However, the therapeutic implications and optimal extent of lymphadenectomy remain contentious. Methods To clarify the prognostic value and optimal extent of lymphadenectomy, the therapeutic index (TI) for each lymph node was analyzed for 279 cases that had undergone lymphadenectomy in a multi-institutional database. Tumor localization was divided into hilar lesions (n = 130), right peripheral lesions (n = 60), and left peripheral lesions (n = 89). In addition, the lymph node station was classified as Level 1 (LV1: hepatoduodenal ligament node), Level 2 (LV2: postpancreatic or common hepatic artery nodes), or Level 3 (LV3: gastrocardiac, left gastric artery, or celiac artery nodes). Results Lymph node metastases were confirmed in 109 patients (39%). Five-y survival rates were 45.3% for N0 disease, 27.1% for LV1-LNM, 22.9% for LV2-LNM, and 7.3% for LV3-LNM (P < 0.001). LV3-LNM were the most frequent and earliest recurrence outcome, including multisite recurrence, followed by LV2, LV1, and N0 disease. The 5-year TI (5year-TI) for lymphadenectomy was 7.2 for LV1, 5.5 for LV2, and 1.9 for LV3. Regarding tumor location, hilar lesions showed 5-year TI > 5.0 in LV1 and LV2, whereas bilateral peripheral lesions showed 5-year TI > 5.0 in LV1. Conclusion The implications and extent of lymphadenectomy for ICC appear to rely on tumor location. In the peripheral type, the benefit of lymphadenectomy would be limited and dissection beyond LV1 should be avoided, while in the hilar type, lymphadenectomy up to LV2 could be recommended.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Immune checkpoint inhibitors, including anti-programmed cell death 1 (PD-1) antibody, provide improved clinical outcome in certain cancers. However, pancreatic ductal adeno-carcinoma (PDAC) is refractory to PD-1 blockade therapy due to poor immune response. Oncolytic virotherapy is a novel approach for inducing immunogenic cell death (ICD). We demonstrated the therapeutic potential of p53-expressing telo-merase-specific oncolytic adenovirus OBP-702 to induce ICD and anti-tumor immune responses in human PDAC cells with different p53 status (Capan-2, PK-59, PK-45H, Capan-1, MIA PaCa-2, BxPC-3) and murine PDAC cells (PAN02). OBP-702 significantly enhanced ICD with secretion of extracel-lular adenosine triphosphate and high-mobility group box pro-tein B1 by inducing p53-mediated apoptosis and autophagy. OBP-702 significantly promoted the tumor infiltration of CD8+ T cells and the anti-tumor efficacy of PD-1 blockade in a subcutaneous PAN02 syngeneic tumor model. Our results suggest that oncolytic adenovirus-mediated p53 overexpres-sion augments ICD and the efficacy of PD-1 blockade therapy against cold PDAC tumors. Further in vivo experiments would be warranted to evaluate the survival benefit of tumor-bearing mice in combination therapy with OBP-702 and PD-1 blockade.

kn-abstract=Background. Body weight loss (BWL) and skeletal muscle loss (SML) are inevitable after gastrectomy for gastric cancer (GC) and can decrease patients’ quality of life (QOL) and survival.<br>
Objective. The aim of this retrospective study was to evaluate the effect of perioperative and post-discharge patient participation in continuous nutritional counseling (CNC) on post-gastrectomy BWL and SML.<br>
Methods. Ninety-three patients with GC who underwent curative gastrectomy between March 2018 and July 2019 were analyzed. Patients received either pre-discharge nutritional counseling alone (control group, n = 49) or patient-participation CNC (CNC group, n = 44) after gastrectomy. Differences between percentage BWL (%BWL), percentage SML (%SML), and nutrition-related blood parameters between the preoperative values and those at 12 months after surgery were compared between the groups.<br>
Results. Compared with the control group, %BWL was significantly lower in the CNC group at 1 month (−6.2 ± 2.5% vs. −7.9 ± 3.3%, p = 0.005), 6 months (−7.8 ± 6.6% vs. −12.3 ± 6.4%, p = 0.001) and 12 months (−7.9 ± 7.6% vs. −13.2 ± 8.2%, p = 0.002), and %SML was significantly lower in the CNC group at 12 months (−5.3 ± 10.3% vs. −12.8 ± 12%, p = 0.002). Regarding nutrition-related blood parameters, change in total cholesterol was significantly lower in the CNC group than the control group at 12 months after surgery (p = 0.02). Multivariate analysis identified no CNC as an independent risk factor for severe BWL (p = 0.001) and SML (p = 0.006) at 12 months after surgery.<br>
Conclusions. Following gastrectomy, patient-participation CNC prevented postoperative BWL and SML after surgery. These results support the induction of such a CNC program in these patients.

kn-title=RNA editing facilitates the enhanced production of neoantigens during the simultaneous administration of oxaliplatin and radiotherapy in colorectal cancer
en-subtitle=

en-abstract=
kn-abstract=Most cases of colorectal cancers (CRCs) are microsatellite stable (MSS), which frequently demonstrate lower response rates to immune checkpoint inhibitors (ICIs). RNA editing produces neoantigens by altering amino acid sequences. In this study, RNA editing was induced artificially by chemoradiation therapy (CRT) to generate neoantigens in MSS CRCs. Altogether, 543 CRC specimens were systematically analyzed, and the expression pattern of ADAR1 was investigated. In vitro and in vivo experiments were also performed. The RNA editing enzyme ADAR1 was upregulated in microsatellite instability-high CRCs, leading to their high affinity for ICIs. Although ADAR1 expression was low in MSS CRC, CRT including oxaliplatin (OX) treatment upregulated RNA editing levels by inducing ADAR1. Immunohistochemistry analyses showed the upregulation of ADAR1 in patients with CRC treated with CAPDX (capecitabine +OX) radiation therapy relative to ADAR1 expression in patients with CRC treated only by surgery (p <0.001). Compared with other regimens, CRT with OX effectively induced RNA editing in MSS CRC cell lines (HT29 and Caco2, p <0.001) via the induction of type 1 interferon-triggered ADAR1 expression. CRT with OX promoted the RNA editing of cyclin I, a neoantigen candidate. Neoantigens can be artificially induced by RNA editing via an OX-CRT regimen. CRT can promote proteomic diversity via RNA editing.

kn-title=Favorable control of hepatocellular carcinoma with peritoneal dissemination by surgical resection using indocyanine green fluorescence imaging: a case report and review of the literature
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background The optimal management for peritoneal dissemination in patients with hepatocellular carcinoma remains unclear. Although several reports have described the usefulness of surgical resection, the indications should be carefully considered. Herein, we report the case of a patient with hepatocellular carcinoma with peritoneal recurrence who underwent surgical resection using an indocyanine green fluorescence navigation system and achieved favorable disease control. Case presentation A 45-year-old Asian woman underwent left hemihepatectomy for a ruptured hepatocellular carcinoma. Seventeen months after the initial surgery, a single nodule near the cut surface of the liver was detected on computed tomography, along with elevation of tumor markers. The patient was diagnosed with peritoneal metastasis and underwent a surgical resection. Twelve months later, a single nodule on the dorsal side of the right hepatic lobe was detected on computed tomography, and we performed surgical resection. Indocyanine green (0.5 mg/kg) was intravenously administered 3 days before surgery, and the indocyanine green fluorescence imaging system revealed clear green fluorescence in the tumor, which helped us perform complete resection. Indocyanine green fluorescence enabled the detection of additional lesions that could not be identified by preoperative imaging, especially in the second metastasectomy. There was no further recurrence at 3 months postoperatively. Conclusion When considering surgical intervention for peritoneal recurrence in patients with hepatocellular carcinoma, complete resection is mandatory. Given that disseminated nodules are sometimes too small to be detected by preoperative imaging studies, intraoperative indocyanine green fluorescence may be an essential tool for determining the indications for surgical resection.

kn-title=Adenomatoid mesothelioma arising from the diaphragm: a case report and review of the literature
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background Adenomatoid mesothelioma is a rare subtype of malignant mesothelioma that can be confused with adenomatoid tumors, which are classified as benign. The clinical features and optimal management of adenomatoid mesothelioma have not been elucidated in the literature. In this report, we present an extremely rare case of adenomatoid mesothelioma that developed on the peritoneal surface of the diaphragm as well as a literature review of adenomatoid mesothelioma in the abdominal cavity. Case presentation The patient was a 61-year-old Japanese woman who had undergone resection of a malignant peripheral nerve sheath tumor of the hand 18 years prior. She was diagnosed with clinical stage I lung adenocarcinoma on follow-up chest radiography. Simultaneously, a 20-mm enhancing nodule with slow growth on the right diaphragm was detected on contrast-enhanced computed tomography. She presented no specific clinical symptoms. At this point, the lesion was suspected to be a hypervascular tumor of borderline malignancy, such as a solitary fibrous tumor. After a left upper lobectomy for lung adenocarcinoma, she was referred to our department, and laparoscopic tumor resection was performed. Adenomatoid tumors were also considered based on the histopathological and immunohistochemical analyses, but we made the final diagnosis of adenomatoid mesothelioma using the results of the genetic profile. The patient remains alive, with no recurrence noted 6 months after surgery. Conclusion We encountered a valuable case of adenomatoid mesothelioma of peritoneal origin. There are some previously reported cases of adenomatoid mesothelioma and adenomatoid tumors that may need to be recategorized according to the current classification. It is important to accumulate and share new findings to clarify the clinicopathological characteristics and genetic status of adenomatoid mesothelioma.

kn-title=Optimal surveillance of intraductal papillary mucinous neoplasms of the pancreas focusing on remnant pancreas recurrence after surgical resection
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background The international consensus guidelines for intraductal papillary mucinous neoplasm of the pancreas (IPMN) presented clinical features as indications for surgery. Whereas surveillance for recurrence, including de novo lesions, is essential, optimal surveillance protocols have not been established. Aim and methods This study aimed to assess the clinical features of recurrence at the remnant pancreas (Rem-Panc) and extra-pancreas (Ex-Panc) after surgery for IPMN. Ninety-one patients of IPMN that underwent detailed preoperative assessment and pancreatectomy were retrospectively analyzed, focusing especially on the type of recurrence. Results The IPMNs were finally diagnosed as low-grade dysplasia (LDA, n = 42), high-grade dysplasia (HAD, n = 19), and invasive carcinoma (IPMC, n = 30). Recurrence was observed in 26 patients (29%), of which recurrence was seen at Rem-Panc in 19 patients (21%) and Ex-Panc in 7 patients (8%). The frequency of Rem-Panc recurrence was 10% in LDA, 21% in HDA, and 37% in IPMC. On the other hand, Ex-Panc recurrence was observed only in IPMC (23%). Ex-Panc recurrence showed shorter median recurrence-free survival (RFS) and overall survival (OS) than Rem-Panc recurrence (median RFS 8 months vs. 35 months, p < 0.001; median OS 25 months vs. 72 months, p < 0.001). Regarding treatment for Rem-Panc recurrence, repeat pancreatectomy resulted in better OS than no repeat pancreatectomy (MST 36 months vs. 15.5 months, p = 0.033). On multivariate analysis, main duct stenosis or disruption as a preoperative feature (hazard ratio [HR] 10.6, p = 0.002) and positive surgical margin (HR 4.4, p = 0.018) were identified as risk factors for Rem-Panc recurrence. Conclusions The risk factors for Rem-Panc and Ex-Panc recurrence differ. Therefore, optimal surveillance on these features is desirable to ensure that repeat pancreatectomy for Rem-Panc recurrence can be an appropriate surgical intervention.

kn-title=Surgical resection of mixed neuroendocrine-non-neuroendocrine neoplasm in the biliary system: a report of two cases
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background Mixed neuroendocrine-non-neuroendocrine neoplasm (MINEN) is a rare disease and there is scarce literature on its diagnosis, treatment, and prognosis. We encountered two unusual cases of MINEN in the biliary tract, one in the ampulla of Vater and the other in the distal bile duct. In this report, we describe the clinical course of these two cases in detail. Case presentation Case 1: A 69-year-old woman presented with a chief complaint of epigastric pain. When endoscopic sphincterotomy and retrograde biliary drainage were performed for gallstone pancreatitis, an ulcerated lesion was found in the ampulla of the Vater. Based on the biopsy results, the lesion was diagnosed as the ampulla of Vater carcinoma and subtotal stomach-preserving pancreatoduodenectomy (SSPPD) was performed. Postoperative histopathological examination revealed the coexistence of adenocarcinoma and neuroendocrine carcinoma components, consistent with the diagnosis of MINEN. In addition, lymph node metastasis was found on the dorsal side of the pancreas and the metastatic component was adenocarcinoma. Adjuvant chemotherapy with etoposide and cisplatin was administered for 6 months, and presently the patient is alive without recurrence 64 months after surgery. Case 2: A 79-year-old man presented with a chief complaint of anorexia. Cholangiography showed severe stenosis of the distal bile duct. A biopsy was conducted from the stenotic lesion and it revealed the lesion to be adenocarcinoma. A diagnosis of distal bile duct carcinoma was made, and SSPPD was performed. Histopathological examination revealed the coexistence of adenocarcinoma and neuroendocrine carcinoma components, and the tumor was confirmed as MINEN of the distal bile duct. No adjuvant chemotherapy was administered due to the poor performance status. 7 months later, the patient was found to have a liver metastasis. Conclusion We experienced two valuable cases of biliary MINEN. To identify better treatments, it is important to consider the diversity of individual cases and to continue sharing a variety of cases with different presentations.

kn-title=Surgical technique of suprapancreatic D2 lymphadenectomy focusing on the posterior hepatic plexus for advanced gastric cancer
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Purpose<br>
Although D2 lymphadenectomy is currently considered a standard procedure for advanced gastric cancer (GC) worldwide, there is room for discussion about the appropriate range of suprapancreatic D2 lymphadenectomy. Focusing on the posterior hepatic plexus (PHP), which is not well recognized, we developed a surgical technique of suprapancreatic D2 lymphadenectomy, which we have called PHP-D2, and its short-term and long-term efficacies were evaluated in comparison with non-PHP-D2.<br>
<br>
Methods<br>
GC patients who underwent distal gastrectomy with D2 lymphadenectomy between July 2006 and May 2013 were enrolled, from which patients who had peritoneal metastasis and/or were peritoneal cytology-positive during surgery were excluded. Their medical records were retrospectively reviewed.<br>
<br>
Results<br>
Ninety-two patients (non-PHP-D2: 48, PHP-D2: 44) were enrolled. Shorter operation time (330 min vs 275 min, p < 0.0001) and less blood loss (290 mL vs 125 mL, p < 0.0001) were observed in PHP-D2, and no pancreatic fistulas were observed in PHP-D2. More lymph nodes of #11p (1 vs 1.5, p = 0.0328) and #12a lymph nodes (0 vs 1, p = 0.0034) were retrieved in PHP-D2, with no significant differences in #8a and #9 lymph nodes. Lymphatic recurrence was significantly less in PHP-D2 (p = 0.0166), and univariate and multivariate analyses showed that non-PHP-D2 was a significant risk factor for lymphatic recurrence (p = 0.0158), although there were no significant differences between non-PHP-D2 and PHP-D2 in 5-year overall survival and 5-year relapse-free survival.<br>
<br>
Conclusion<br>
PHP-D2 was a safe and feasible procedure that had the potential to reduce lymphatic recurrence, and it can be a standard procedure of D2 lymphadenectomy for advanced GC.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Aim: To evaluate whether PCR-reverse sequence-specific oligonucleotide can examine the concordance between liquid biopsy and metastatic lesions with acquired resistance. Materials & methods: We examined acquired mutations in chemoresistant lesions and blood obtained from four patients with RAS wildtype metastatic colorectal cancer who underwent treatment with anti-epidermal growth factor receptor antibodies. Results: In one patient, metastatic lesions harbored diverse acquired mutations in KRAS in all seven metastases; the two acquired mutations were detectable in blood collected after the patient acquired resistance. None of the other patients exhibited liquid biopsy mutations, except one, with a BRAF mutation confirmed in primary tumor and peritoneal dissemination. Conclusion: Liquid biopsy based on PCR-reverse sequence-specific oligonucleotide is a successful procedure for capturing acquired mutations with precise information on the RAS mutational spectrum.

kn-title=Left Hemihepatectomy for Hepatocellular Carcinoma Following Esophagectomy with Retrosternal Gastric Tube Reconstruction for Esophageal Cancer
en-subtitle=

en-abstract=
kn-abstract=Approximately 4% of patients with esophageal cancer develop a second primary malignancy in the upper gastrointestinal trunk. However, hepatectomy following esophagectomy for esophageal cancer has rarely been reported. We report the case of a 70-year-old man who underwent an esophagectomy for esophageal cancer with retrosternal gastric tube reconstruction. Nine years later, he developed hepatocellular carcinoma with tumor thrombus involving the left portal vein, and was successfully treated with left hemihepatectomy. Special attention should be paid to avoiding incidental injury of the gastric tube as well as the right gastroepiploic artery during the hepatectomy.

kn-title=Impact of lymph node dissection on clinical outcomes of intrahepatic cholangiocarcinoma: Inverse probability of treatment weighting with survival analysis
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background: Lymph node metastasis (LNM) has been established as a critical risk factor for prognosis in intrahepatic cholangiocarcinoma (ICC). The clinical implications of lymph node dissection (LND) have been debated. This study aimed to clarify the prognostic impact of LND by multicenter retrospective analysis.<br>
<br>
Methods: A total of 310 ICC patients who had undergone curative resection between 2000 and 2016 were retrospectively analyzed. The prognostic impact of LND was estimated under an inverse probability of treatment weighting (IPTW) approach using propensity scores.<br>
<br>
Results: LND was performed for 224 patients (72%), with LNM pathologically confirmed in 90 patients (40%). Prognosis was poorer for patients with LNM (median survival, 16.9 months) than for those without (57.2 months; P < .0001). One-, 3-, and 5-year overall survival rates (OS) were comparable among LND+ (81.6%, 48.0%, and 37.5%, respectively) and LND- groups (81.6%, 55.4%, and 44.6%, respectively). However, advanced tumor, as characterized by larger tumor, multinodular lesions, and serosal invasion, was significantly more frequent in the LND+ group than in the LND- group. After IPTW adjusting for imbalances, 1-, 3-, and 5-year OS were better in the LND+ group (83.5%, 52.2%, and 42.8%, respectively) than in the LND- group (71.9%, 32.4%, and 23.4%, respectively; P = .046). LND thus showed significant prognostic impact (hazard ratio = 0.58, 95%CI = |0.39|-|0.84|, P = .005), especially in hilar ICC. However, peripheral ICC displayed no therapeutic benefit from LND.<br>
<br>
Conclusions: LND could have a significant role to play in improving oncologic outcomes. Therapeutic LND should be implemented on the basis of tumor location and tumor advancement.

kn-title=Dramatic Response to Carboplatin Plus Paclitaxel in Pancreatic Mucinous Cystadenocarcinoma with Liver Metastasis
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Mucinous cystic neoplasm (MCN) of the pancreas is a rare cystic tumor occurring in the pancreatic body and tail in young to middle-aged women that is pathologically characterized by an ovarian-like stroma. Chemotherapy for recurrent/advanced pancreatic MCN has been based on chemotherapy regimens for pancreatic ductal adenocarcinoma, but the prognosis is poor. We herein report a 37-year-old woman with pancreatic mucinous cystadenocarcinoma with liver metastasis that responded dramatically to carboplatin plus paclitaxel therapy (CBDCA+PTX). CBDCA+PTX may be a treatment option for recurrent/advanced pancreatic MCN with an ovarian-like stroma.

kn-title=Gastroenteropancreatic neuroendocrine tumor of the accessory papilla of the duodenum: a case report
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=BackgroundContrary to the increasing incidence of gastroenteropancreatic neuroendocrine tumors (GEP-NETs), GEP-NETs of the accessory papilla of the duodenum are extremely rare. Furthermore, there have been no recommendations regarding the treatment strategy for GEP-NETs of the accessory papilla of the duodenum. We present a case of GEP-NET of the accessory papilla of the duodenum successfully treated with robotic pancreatoduodenectomy.Case presentationA case of a 70-year-old complaining of no symptoms was diagnosed with GEP-NET of the accessory papilla of the duodenum. A 8-mm tumor was located at the submucosal layer with a biopsy demonstrating a neuroendocrine tumor grade 1. The patient underwent robotic pancreatoduodenectomy as curative resection for the tumor. The total operative time was 406 min with an estimated blood loss of 150 mL. The histological examination revealed a well-differentiated neuroendocrine tumor with low Ki-67 index (<1%). In the posterior areas of the pancreas, the lymph node metastases were detected. The patient was followed up for 6 months with no recurrence postoperatively.ConclusionsConsidering the potential risks of the lymph node metastases, the standard treatment strategy for GEP-NETs of the accessory papilla of the duodenum should be radical resection with pancreatoduodenectomy. Minimally invasive approach can be the alternative to the conventional open surgery.

kn-title=Preoperative prognostic nutritional index predicts postoperative infectious complications and oncological outcomes after hepatectomy in intrahepatic cholangiocarcinoma
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background: In the surgical treatment of intrahepatic cholangiocarcinoma (ICC), postoperative complications may be predictive of long-term survival. This study aimed to identify an immune-nutritional index (INI) that can be used for preoperative prediction of complications.<br>
Patients and methods: Multi-institutional data from 316 patients with ICC who had undergone surgical resection were retrospectively analysed, with a focus on various preoperative INIs.<br>
Results: Severe complications (Clavien-Dindo grade III-V) were identified in 66 patients (20.8%), including Grade V complications in 7 patients (2.2%). Comparison of areas under the receiver operating characteristic curve (AUCs) among various INIs identified the prognostic nutritional index (PNI) as offering the highest predictive value for severe complications (AUC = 0.609, cut-off = 50, P = 0.008). Multivariate analysis revealed PNI < 50 (odds ratio [OR] = 2.22, P = 0.013), hilar lesion (OR = 2.46, P = 0.026), and long operation time (OR = 1.003, P = 0.029) as independent risk factors for severe complications. In comparing a high-PNI group (PNI >= 50, n = 142) and a low-PNI group (PNI < 50, n = 174), the low-PNI group showed higher rates of both major complications (27% vs. 13.4%; P = 0.003) and infectious complications (14.9% vs. 3.5%; P = 0.0021). Furthermore, median survival time and 1- and 5-year overall survival rates were 34.2 months and 77.4 and 33.8% in the low-PNI group, respectively, and 52.4 months and 89.3 and 47.5% in the high-PNI group, respectively (P = 0.0017). <br>
Conclusion: Preoperative PNI appears useful as an INI correlating with postoperative severe complications and as a prognostic indicator for ICC.

kn-title=Accreditation as a qualified surgeon improves surgical outcomes in laparoscopic distal gastrectomy
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Purpose: The Endoscopic Surgical Skill Quantification System for qualified surgeons (QSs) was introduced in Japan to improve surgical outcomes. This study reviewed the surgical outcomes after initial experience performing laparoscopic distal gastrectomy (LDG) and evaluated the improvement in surgical outcomes following accreditation as a QS.<br>
Methods: Eighty-seven consecutive patients who underwent LDG for gastric cancer by a single surgeon were enrolled in this study. The cumulative sum method was used to analyze the learning curve for LDG. The surgical outcomes were evaluated according to the two phases of the learning curve (learning period vs. mastery period) and accreditation (non-QS period vs. QS period).<br>
Results: The learning period for LDG was 48 cases. Accreditation was approved at the 67th case. The operation time and estimated blood loss were significantly reduced in the QS period compared to the non-QS period (230 vs. 270 min, p<0.001; 20.5 vs. 59.8 ml, p=0.024, respectively). Furthermore, the major complication rate was significantly lower in the QS period than in the non-QS period (0 vs. 10.6%, p=0.044).<br>
Conclusions: Experience performing approximately 50 cases is required to reach proficiency in LDG. After receiving accreditation as a QS, the surgical outcomes, including the complication rate, were improved.

kn-title=Long-term survival without recurrence after surgery for gastric yolk sac tumor-like carcinoma: a case report
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background Gastric yolk sac tumor (YST)-like carcinoma is extremely rare, and its prognosis is poor, because most patients have widespread metastases at the time of diagnosis. We report a case of gastric YST-like carcinoma with an adenocarcinoma component without metastases in which curative resection was performed. Case presentation A 77-year-old man complaining of melena and dizziness due to anemia was diagnosed with poorly differentiated adenocarcinoma in the gastric cardia, with a benign ulcer in the gastric body. He underwent total gastrectomy with D2 lymph node dissection for the tumor. Histological examination of the resected specimens revealed a mixture of reticular and glandular neoplastic components morphologically. In the reticular area, an endodermal sinus pattern and some Schiller-Duval bodies were confirmed. Gastric YST-like carcinoma with adenocarcinoma components, T2N0M0 Stage IB, was diagnosed. Immunohistochemical analysis showed that the YST was positive for carcinoembryonic antigen (CEA), alpha-fetoprotein (AFP) and p53. In contrast, the adenocarcinoma was positive for p53 and negative for CEA and AFP. The patient remained healthy as of 7 years postoperatively, with no recurrence. Conclusions Routine medical examinations or endoscopic examinations for accidental symptom may be helpful for early diagnosis and good prognosis for gastric YST-like carcinoma, although the prognosis is generally poor.

kn-abstract=We present the first case of laparoscopic left lateral segmentectomy for hepatocellular carcinoma (HCC) in a patient with hemophilia A, acquired hepatitis C, and high-titer factor VIII inhibitor, which was confirmed by preoperative diagnosis. He underwent laparoscopic left lateral segmentectomy with the administration of recombinant activated factor VII. Surgery could be performed with reduced intraoperative hemorrhage. He experienced postoperative intra-abdominal wall hemorrhage, which was successfully managed with red cell concentrates transfusion and administration of recombinant activated factor VII. Laparoscopic hepatectomy can be applied for hemophilia patients with high titer inhibitors.

kn-title=Surgical training model and safe implementation of robotic pancreatoduodenectomy in Japan: a technical note
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background</br>
Growing evidence for the advantages of robotic pancreatoduodenectomy (RPD) has been demonstrated internationally. However, there has been no structured training program for RPD in Japan. Herein, we present the surgical training model of RPD and a standardized protocol for surgical technique.</br>
Methods</br>
The surgical training model and surgical technique were standardized in order to implement RPD safely, based on the Dutch training system collaborated with the University of Pittsburgh Medical Center.</br>
Results</br>
The surgical training model included various trainings such as basic robotic training, simulation training, biotissue training, and a surgical video review. Furthermore, a standardized protocol on the surgical technique was established to understand the tips, tricks, and pitfalls of RPD.</br>
Conclusions</br>
Safe implementation of RPD can be achieved through the completion of a structured training program and learning surgical technique. A nationwide structured training system should be developed to implement the program safely in Japan.

kn-abstract=Surgery is the only curative treatment option for pancreatic cancer, but patients often develop postoperative recurrence. Surgical invasiveness might be involved in the mechanism of recurrence. The associations among inflammation caused by surgery, neutrophils, and cancer metastasis were investigated. At first, neutrophil extracellular traps (NETs) were examined in clinical specimens, and NETs were observed around metastatic tumors. To explore how NETs were induced, neutrophils were cultured with pancreatic cancer or in cancer-conditioned medium. Neutrophils formed NETs when they were cultured with pancreatic cancer or even its conditioned medium. The effects of NETs on cancer cells were further investigated in vitro and in vivo. NETs induced the epithelial to mesenchymal transition in cancer cells and thereby promoted their migration and invasion. HMGB1 derived from NETs appeared to potentiate the malignancy of cancer cells. In a mouse model of liver metastasis with inflammation, NETs participated in the metastatic process by enhancing extravasation. Interestingly, thrombomodulin degraded HMGB1 and consequently inhibited the induction of NETs, thereby preventing pancreatic cancer metastasis to the liver. In conclusion, NETs interact reciprocally with pancreatic cancer cells, which play a pivotal role in inflammation-associated metastasis. Targeting NETs with thrombomodulin can be a novel strategy to improve the surgical outcome of pancreatic cancer patients.

kn-title=Hemobilia after bile duct resection: perforation of pseudoaneurysm into intra-pancreatic remnant bile duct: a case report
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background</br>
Hemobilia occurs mainly due to iatrogenic factors such as impairment of the right hepatic or cystic artery, and/or common bile duct in hepatobiliary-pancreatic surgery. However, little or no cases with hemobilia from the intra-pancreatic remnant bile duct after bile duct resection (BDR) has been reported. Here, we report a case of massive hemobilia due to the perforation of psuedoaneurysm of the gastroduodenal artery (GDA) to the intra-pancreatic remnant bile duct after hepatectomy with BDR.</br>
Case presentation</br>
A 68-year-old male underwent extended right hepatectomy with BDR for gallbladder carcinoma. He presented with upper gastrointestinal bleeding 2 months after the initial surgery. Upper endoscopy identified a blood clot from the ampulla of Vater and simultaneous endoscopic balloon tamponade contributed to temporary hemostasis. Abdominal CT and angiography revealed a perforation of the psuedoaneurysm of the GDA to the intra-pancreatic remnant bile duct resulting in massive hemobilia. Subsequent selective embolization of the pseudoaneurysm with micro-coils could achieve complete hemostasis. He survived without any recurrence of cancer and bleeding.</br>
Conclusion</br>
Hemobilia could occur in a patient with BDR due to perforation of the pseudoaneurysm derived from the GDA to the intra-pancreatic remnant bile duct. Endoscopic balloon tamponade was useful for a temporal hemostasis and a subsequent radiologic interventional approach.

kn-title=A novel modified hanging maneuver in laparoscopic left hemihepatectomy
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Introduction</br>
The liver hanging maneuver is an essential technique for controlling bleeding in hepatectomy, however it is often difficult in laparoscopic major hepatectomy. The present study describes a novel modified hanging maneuver in laparoscopic left hemihepatectomy.</br>
Presentation of case</br>
A 29-year-old female underwent laparoscopic left hemihepatectomy for mucinous cystic neoplasm. After mobilizing the left lobe, the liver parenchyma was dissected along the demarcation line. For the hanging technique, the upper edge of the hanging tape was placed on the lateral side of the left hepatic vein, and fixed with the Falciform ligament. The lower edge of the tape was extracted outside the abdomen. Accordingly the hanging tape can be controlled extraperitoneally during the liver parenchyma dissection.</br>
Discussion</br>
This technique includes several advantages including no need of assistance using forceps, easy control of the hanging tape extraperitoneally, outflow control, better exposure of surgical field, and helpful guide of the liver dissection line toward the root of the left hepatic vein.
Conclusion</br>
Our novel modified hanging maneuver is easy and reproducible to use in laparoscopic left hemihepatectomy. Moreover, this technique can be applied to other laparoscopic hepatectomy.

kn-title=Efficacy and safety of scheduled early endoscopic ultrasonography‐guided ethanol reinjection for patients with pancreatic neuroendocrine tumors: Prospective pilot study
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Endoscopic ultrasonography (EUS)‐guided ethanol injection was recently proposed for treatment of patients with small pancreatic neuroendocrine tumors (p‐NET); however, tips on how to carry out safe and effective procedures are unclear. We launched a pilot study for scheduled early EUS‐guided ethanol reinjection for small p‐NET. Major eligibility criteria were presence of pathologically diagnosed grade (G) 1 or G2, tumor size ≤2 cm and being a poor or rejected candidate for surgery. For the treatment, we used a 25‐gauge needle and pure ethanol. Contrast‐enhanced computed tomography (CE‐CT) was carried out on postoperative day 3, and if enhanced areas of the tumor were still apparent, an additional session was scheduled during the same hospitalization period. Primary endpoint was complete ablation rate at 1 month after treatment, and secondary endpoint was procedure‐related adverse events. A total of five patients were treated. Median size of the tumor was 10 (range: 7–14) mm. Of the five patients, three underwent an additional session. Median volume of ethanol injection per session was 0.8 (range: 0.3–1.0) mL, and the total was 1.0 (0.9–1.8) mL. Complete ablation was achieved in four of the five tumors (80%) with no adverse events. During 1 year of follow up, none of the patients reported any procedure‐related adverse events, and no recurrence of tumor. Scheduled early EUS‐guided ethanol reinjection appears to be safe and effective for treating small p‐NET (UMIN number: 000018834).

kn-title=The efficacy of pancreatic juice cytology with liquid-based cytology for evaluating malignancy in patients with intraductal papillary mucinous neoplasm
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background</br>
Pancreatic juice cytology (PJC) is a tool for diagnosing malignant intraductal papillary mucinous neoplasm (IPMN); however, the accuracy is insufficient using the conventional method. Liquid-based cytology (LBC) improves the cell recovery rate, and almost all cells can be evaluated. We evaluated the efficacy of PJC with LBC for malignant IPMN.</br>
Methods</br>
We retrospectively analyzed 90 patients with suspected malignant IPMN who underwent PJC before pancreatectomy. PJC with smear and LBC methods was conducted in 52 patients (between June 2003 to December 2011) and 38 patients (between January 2012 to December 2018). Based on the imaging studies, all of the patients were classified according to the international consensus guidelines for IPMN revised in 2017.</br>
Results</br>
Of the 90 patients, 43 (48%) had malignant IPMN (high-grade dysplasia or invasive carcinoma), and the remaining patients had non-malignant IPMN (intermediate- or low-grade dysplasia). LBC increased the accuracy of PJC for the diagnosis of malignant IPMN (smear method: 56% [29/52] vs. LBC method: 76% [29/38]; P = 0.044). In a multivariate analysis, LBC was a significant factor influencing the accurate diagnosis of PJC (odds ratio: 3.52; P = 0.021). Furthermore, LBC increased the accuracy of PJC for malignant IPMN in patients with worrisome features (smear method: 66% [19/29] vs. LBC method: 93% [14/15]; P = 0.043).</br>
Conclusions</br>
LBC increases the accuracy of PJC for diagnosing malignant IPMN compared with the conventional smear method.

kn-title=Efficacy of surgical management for recurrent intrahepatic cholangiocarcinoma: A multi-institutional study by the Okayama Study Group of HBP surgery
en-subtitle=
kn-subtitle=

kn-abstract=Background The prognosis of intrahepatic cholangiocarcinoma (ICC) has been poor, because of the high recurrence rate even after curative surgery. This study aimed to evaluate the prognostic impact of surgical resection of recurrent ICC. Patients and methods A total of 345 cases of ICC who underwent hepatectomy with curative intent in 17 institutions were retrospectively analyzed, focusing on recurrence patterns and treatment modalities for recurrent ICC. Results Median survival time and overall 5-year recurrence-free survival rate were 17.8 months and 28.5%, respectively. Recurrences (n = 223) were classified as early (recurrence at <= 1 year, n = 131) or late (recurrence at >1 year, n = 92). Median survival time was poorer for early recurrence (16.3 months) than for late recurrence (47.7 months,p<0.0001). Treatment modalities for recurrence comprised surgical resection (n = 28), non-surgical treatment (n = 134), and best supportive care (BSC) (n = 61). Median and overall 1-/5-year survival rates after recurrence were 39.5 months and 84.6%/36.3% for surgical resection, 14.3 months and 62.5%/2.9% for non-surgical treatment, and 3 months and 4.8%/0% for BSC, respectively (p<0.0001). Multivariate analysis identified early recurrence, simultaneous intra- and extrahepatic recurrence, and surgical resection of recurrence as significant prognostic factors. In subgroup analyses, surgical resection may have positive prognostic impacts on intra- and extrahepatic recurrences, and even on early recurrence. However, simultaneous intra- and extrahepatic recurrence may not see any survival benefit from surgical management. Conclusion Surgical resection of recurrent ICC could improve survival after recurrence, especially for patients with intra- or extrahepatic recurrence as resectable oligo-metastases.

kn-title=Laparoscopic liver resection of segment seven: A case report and review of surgical techniques
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Introduction</br>
Laparoscopic liver resection of segment seven (LLR-S7) is a technically challenging procedure due to its anatomical location and difficult accessibility. Herein, we present our experience with LLR-S7, and demonstrate a literature review regarding surgical techniques.</br>
Presentation of case</br>
A 28-year-old female was diagnosed with rectosigmoid cancer and synchronous liver metastases at the segment three (S3) and S7, which were treated with laparoscopic procedure. After the completely mobilization of the right lobe, the Glissonean pedicle of S7 (G7) was intrahepatically transected. The right hepatic vein was exposed to identify the venous branch of S7 (V7). Finally the liver parenchyma between RHV and dissection line was divided.</br>
Discussion</br>
Various laparoscopic approaches for S7 have been reported including the Glissonian approach from the hilum, the intrahepatic Glissonean approach, the caudate lobe first approach, and the lateral approach from intercostal ports. To perform LLR-S7 safely, it is important to understand the advantage of each technique including the trocar placement and approaches to S7 by laparoscopy.</br>
Conclusion</br>
We present our experience of LLR-S7 for the tumor located at the top of S7, successfully performed with the intrahepatic Glissonean approach. LLR-S7 can be performed safely with advanced laparoscopic techniques and sufficient knowledge on various approaches for S7.

kn-title=Oncolytic Virus-Mediated Targeting of the ERK Signaling Pathway Inhibits Invasive Propensity in Human Pancreatic Cancer
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Pancreatic ductal adenocarcinoma (PDAC) cells have an exceptional ability to invade nerves through pronounced crosstalk between nerves and cancer cells; however, the mechanism of PDAC cell invasion remains to be elucidated. Here, we demonstrate the therapeutic potential of telomerase-specific oncolytic adenoviruses, OBP -301 and tumor suppressor p53-armed OBP-702, against human PDAC cells. Highly invasive PDAC cells exhibited higher levels of phosphorylated extracellular signal-regulated kinases 1 and 2 (ERK1/2) expression independent of KRAS expression; ERK1/2 inhibitor or small interfering RNA (siRNA) treatment significantly reduced the migration and invasion of PDAC cells, suggesting that the ERK signaling pathway is associated with the invasiveness of PDAC cells. OBP-702 infection suppressed ERK signaling and inhibited PDAC cell migration and invasion more efficiently than OBP-301. OBP-702 also effectively inhibited PDAC cell invasion even when invasiveness was enhanced by administration of motility stimulators, such as nerve and neurosecretory factors. Moreover, noninvasive whole-body imaging analyses showed that OBP-702 significantly suppressed tumor growth in an orthotopic PDAC xenograft model, although both viruses were equally effective against subcutaneous tumors, suggesting that OBP-702 can influence the orthotopic tumor microenvironment. Our data suggest that oncolytic virus-mediated disruption of ERK signaling is a promising antitumor strategy for attenuating the invasiveness of PDAC cells.

kn-title=Pediatric Living Donor Liver Transplantation for Congenital Absence of the Portal Vein With Pulmonary Hypertension: A Case Report
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Few reports of liver transplantation exist in patients with congenital absence of the portal vein and pulmonary hypertension. Living donor liver transplantation is usually performed before exacerbation of pulmonary hypertension. A 7-year-old girl (height: 131.5 cm; weight: 27.4 kg) with congenital absence of the portal vein was diagnosed with pulmonary hypertension (mean pulmonary artery pressure 35 mm Hg), and liver transplantation was planned before exacerbation of pulmonary hypertension. We successfully managed her hemodynamic parameters using low-dose dopamine and noradrenaline under monitoring of arterial blood pressure, central venous pressure, cardiac output, and stroke volume variation. Anesthesia was maintained using air-oxygen-sevoflurane and remifentanil 0.1 to 0.6 μg∙kg-1∙min-1. It is necessary to understand the potential perioperative complications in such cases and to adopt a multidisciplinary team approach in terms of the timing of transplantation and readiness to deal with exacerbation of pulmonary hypertension.

kn-title=Postoperative Course of Serum Albumin Levels and Organ Dysfunction After Liver Transplantation
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background and aims: Postoperative hypoalbuminemia, especially following liver transplantation, can lead to adverse multisystem effects and even death. We investigated the relationship between postoperative albumin levels and organ failure (assessed using Sequential Organ Failure Assessment [SOFA] scores).<br/>
Methods: Sixty liver transplant recipients admitted to the intensive care unit (ICU) from 2012 to 2015 were retrospectively divided into 2 groups: lower albumin (LA) (n=28) and higher albumin (HA) (n=32), using whether serum albumin level fell below 3.0 g/dL during the first postoperative week as the stratifying factor. The SOFA scores (primary endpoint) and associated complications (ascites amount, rejection, re-intubation, abdominal re-operation, thrombosis), additional treatment (dialysis, pleural effusion drainage), and duration of ICU stay (secondary endpoints) of the 2 groups were compared.<br/>
Results: Average serum albumin levels were significantly different between HA and LA groups (3.6 [3.4-3.8] vs 3.1 [2.9-3.3], respectively, P<.05), although the amounts of albumin infused in the 2 groups during the first postoperative week were not different (HA vs LA: 42 [30-71] vs 40 [30-58], respectively, P=.37). Mean daily SOFA scores were not significantly different between the HA and LA groups (8.3 [6.6-9.0] vs 7.2 [6.3-8.6], P=.73), although the HA group had lower mean cardiovascular SOFA sub-scores than the LA group (0.1 [0-0.4] vs 0.4 [0-1.3], P=.032). There were no significant differences between the groups with regard to complication rates and duration of ICU and hospital stays.<br/>
Conclusions: Serum albumin level might not influence cumulative organ function, but it decreases the amount of hemodynamic support required in liver transplant recipients.

kn-title=The relationship between the PD-L1 expression of surgically resected and fine-needle aspiration specimens for patients with pancreatic cancer
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=BACKGROUND:</br>
Recently, therapeutic antibodies against programmed death-1/programmed death-ligand 1 (PD-1/PD-L1) have shown promising clinical results for several solid tumors, including pancreatic cancer. In this study, we evaluated the relationship between the PD-L1 expression of surgical resected and fine-needle aspiration (FNA) specimens for patients with pancreatic cancer.
</br>
METHODS:</br>
Of 121 patients who underwent endoscopic ultrasound-guided (EUS)-FNA before surgery for pancreatic cancer in an academic center, the 94 (78%) with adequate FNA specimens for a histological evaluation were retrospectively analyzed. All the patients had undergone upfront surgery without any chemotherapy or radiotherapy. We performed immunohistochemistry (IHC) staining to investigate the PD-L1 expression in both resected and FNA specimens. The positive-stained cells were counted, and their percentage was used for the investigation.
</br>
RESULTS:</br>
Of the 94 patients, 16 (17%) and 11 (10%) were defined as positive on resected cancer specimens using cutoff points of 5% and 10% positively stained cancer cell counts, respectively. The concordance rates for the positive frequency of PD-L1 expression between resected and FNA specimens were 44% (7/16) and 55% (6/11) when the positivity was set to ≥ 5% and ≥ 10%, respectively. The concordance rates for the negative frequency of PD-L1 expression between two specimens were 97% (76/78) and 99% (82/83) when the positivity was set to ≥ 5% and ≥ 10%, respectively.
</br>
CONCLUSIONS:</br>
Approximately, half of the patients with PD-L1 expression positive and almost all the patients with PD-L1 expression negative could be diagnosed on FNA specimens.

kn-title=Living Donor Liver Transplantation for Acute Liver Failure : Comparing Guidelines on the Prediction of Liver Transplantation
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract= Determining the indications for and timing of liver transplantation (LT) for acute liver failure (ALF) is essential. The King’s College Hospital (KCH) guidelines and Japanese guidelines are used to predict the need for LT and the outcomes in ALF. These guidelines’ accuracy when applied to ALF in different regional and etiological backgrounds may differ. Here we compared the accuracy of new (2010) Japanese guidelines that use a simple scoring system with the 1996 Japanese guidelines and the KCH criteria for living donor liver transplantation (LDLT). We retrospectively analyzed 24 adult ALF patients (18 acute type, 6 sub-acute type) who underwent LDLT in 1998-2009 at our institution. We assessed the accuracies of the 3 guidelines’ criteria for ALF. The overall 1-year survival rate was 87.5%. The new and previous Japanese guidelines were superior to the KCH criteria for accurately predicting LT for acute-type ALF (72% vs. 17%). The new Japanese guidelines could identify 13 acute-type ALF patients for LT, based on the timing of encephalopathy onset. Using the previous Japanese guidelines, although the same 13 acute-type ALF patients (72%) had indications for LT, only 4 patients were indicated at the 1st step, and it took an additional 5 days to decide the indication at the 2nd step in the other 9 cases. Our findings showed that the new Japanese guidelines can predict the indications for LT and provide a reliable alternative to the previous Japanese and KCH guidelines.

kn-title=Syndrome of Inappropriate Antidiuretic Hormone Secretion Following Liver Transplantation
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Syndrome of inappropriate antidiuretic hormone secretion (SIADH) is an extremely rare cause of hyponatremia post-liver transplantation. A 15-year-old Japanese girl with recurrent cholangitis after Kasai surgery for biliary atresia underwent successful living donor liver transplantation. Peritonitis due to gastrointestinal perforation occurred. Hyponatremia gradually developed but improved after hypertonic sodium treatment. One month later, severe hyponatremia rapidly recurred. We considered the hyponatremia’s cause as SIADH. We suspected that tacrolimus was the disease’s cause, so we used cyclosporine instead, plus hypertonic sodium plus water intake restriction, which improved the hyponatremia. Symptomatic hyponatremia manifested by SIADH is a rare, serious complication post-liver transplantation.

kn-abstract=Sarcopenia following liver surgery has been reported as a predictor of poor prognosis. Here we investigated predictors of outcomes in patients with hepatocellular carcinoma (HCC) and attempted to establish a new comprehensive preoperative assessment protocol. We retrospectively analyzed the cases of 254 patients who underwent curative hepatectomy for HCC with Child-Pugh classification A at our hospital between January 2007 and December 2013. Sarcopenia was evaluated by computed tomography measurement. The influence of sarcopenia on outcomes was evaluated. We used multivariate analyses to assess the impact of prognostic factors associated with outcomes, including sarcopenia. Of the 254 patients, 118 (46.5%) met the criteria for sarcopenia, and 32 had an American Society of Anesthesiologists (ASA) physical status &ge;3. The sarcopenic group had a significantly lower 5-year overall survival rate than the non-sarcopenic group (58.2% vs. 82.4% , p＝0.0002). In multivariate analyses of prognostic factors, sarcopenia was an independent predictor of poor survival (hazard ratio [HR]＝2.28, p＝0.002) and poor ASA status (HR＝3.17, p＝0.001). Sarcopenia and poor ASA status are independent preoperative predictors for poor outcomes after hepatectomy. The preoperative identification of sarcopenia and ASA status might enable the development of comprehensive approaches to assess surgical eligibility.

kn-title=Surgical Outcome of Patients Undergoing Pancreaticoduodenectomy: Analysis of a 17-Year Experience at a Single Center
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The operative mortality and morbidity of pancreaticoduodenectomy (PD) remain high. We analyzed PD patientsʼ clinical characteristics and surgical outcomes and discuss how PD clinical outcomes could be improved. We retrospectively reviewed the cases of 400 patients who underwent a PD between January 1998 and April 2014 at Okayama University Hospital, a very-high-volume center. We identified and compared the clinical outcomes between two time periods (period 1: 1998-2006 vs. period 2: 2007-2014). The total postoperative mortality and major complication rates were 0.75 and 15.8 , respectively, and the median postoperative length of stay (LOS) was 32 days. Subsequently, patients who underwent a PD during period 2 had a significantly shorter LOS than those who underwent a PD during period 1 (29 days vs. 38.5 days, p＜0.001). The incidence of mortality and major complications did not differ between the two periods. In our multivariate analysis, period 1 was an independent factor associated with a long LOS (p＜0.001). The improvement of the surgical procedure and perioperative care might be related to the shorter LOS in period 2 and ot the consistently maintained low mortality rate after PD. The development of multimodal strategies to accelerate postoperative recovery may further improve PDʼs clinical outcomes.

kn-title=CD14 upregulation as a distinct feature of non-alcoholic fatty liver disease after pancreatoduodenectomy
en-subtitle=

kn-abstract=AIM: To investigate the pathogenesis of non-alcoholic fatty liver disease (NAFLD) after pancreatoduodenectomy (PD).

METHODS: A cohort of 82 patients who underwent PD at Okayama University Hospital between 2003 and 2009 was enrolled and the clinicopathological features were compared between patients with and without NAFLD after PD. Computed tomography (CT) images were evaluated every 6 mo after PD for follow-up. Hepatic steatosis was diagnosed on CT when hepatic attenuation values were 40 Hounsfield units. Liver biopsy was performed for 4 of 30 patients with NAFLD after PD who consented to undergo biopsies. To compare NAFLD after PD with NAFLD associated with metabolic syndrome, liver samples were obtained from 10 patients with NAFLD associated with metabolic syndrome [fatty liver, n = 5; non-alcoholic steatohepatitis (NASH), n = 5] by percutaneous ultrasonography-guided liver biopsy. Double-fluorescence immunohistochemistry was applied to examine CD14 expression as a marker of lipopolysaccharide (LPS)-sensitized macrophage cells (Kupffer cells) in liver biopsy specimens.

RESULTS: The incidence of postoperative NAFLD was 36.6% (30/82). Univariate analysis identified cancer of the pancreatic head, sex, diameter of the main pancreatic duct, and dissection of the nerve plexus as factors associated with the development of NAFLD after PD. Those patients who developed NAFLD after PD demonstrated significantly decreased levels of serum albumin, total protein, cholesterol and triglycerides compared to patients without NAFLD after PD, but no glucose intolerance or insulin resistance. Liver biopsy was performed in four patients with NAFLD after PD. All four patients showed moderate-to-severe steatosis and NASH was diagnosed in two. Numbers of cells positive for CD68 (a marker of Kupffer cells) and CD14 (a marker of LPS-sensitized Kupffer cells) were counted in all biopsy specimens. The number of CD68+ cells in specimens of NAFLD after PD was significantly increased from that in specimens of NAFLD associated with metabolic syndrome specimens, which indicated the presence of significantly more Kupffer cells in NAFLD after PD than in NAFLD associated with metabolic syndrome. Similarly, more CD14+ cells, namely, LPS-sensitized Kupffer cells, were observed in NAFLD after PD than in NAFLD associated with metabolic syndrome. Regarding NASH, more CD68+ cells and CD14+ cells were observed in NASH after PD specimens than in NASH associated with metabolic syndrome. This showed that more Kupffer cells and more LPS-sensitized Kupffer cells were present in NASH after PD than in NASH associated with metabolic syndrome. These observations suggest that after PD, Kupffer cells and LPS-sensitized Kupffer cells were significantly upregulated, not only in NASH, but also in simple fatty liver.

CONCLUSION: NAFLD after PD is characterized by both malnutrition and the up-regulation of CD14 on Kupffer cells. Gut-derived endotoxin appears central to the development of NAFLD after PD.

en-abstract=
kn-abstract=We present a case of living donor liver transplantation to a 3-year disease-free survivor of liver resection for hepatocellular carcinoma (HCC) with major portal vein invasion. A 48-year-old man had HCC in the right lobe with a portal venous tumor thrombus extending into the left portal vein. An extended right lobectomy with thrombectomy was performed to remove the thrombus. Three years after liver resection, the patient experienced liver failure, with massive ascites and jaundice due to the formation of a thrombus in the main and left portal veins. During the 3 years after liver resection, no metastasis or recurrence of HCC had been detected, and tumor markers had been within normal ranges. The portal venous thrombus did not show any arterial enhancement under contrast-enhanced computed tomography, suggesting that the co-existence of any HCC component in the portal venous thrombus may have been negative. Based on these findings, living donor liver transplantation was performed using a right lobe graft from the patientʼs son. The patient is alive at 87 months after the transplantation, with no evidence of HCC recurrence.

kn-abstract=　A 55-year-old man who had been diagnosed with rectal cancer with multiple liver metastases and lymph node metastases on colonoscopy and computed tomography (CT) was referred to Okayama University Hospital for treatment. Based on the diagnosis of non-curative rectal cancer, we planned to perform systematic chemotherapy after surgical resection. We performed a low anterior resection of a 36×35 mm upper rectal moderately differentiated adenocarcinoma with wil-type KRAS. After the resection, a FOLFIRI regimen with cetuximab was given as the first-line chemotherapy. Although metastatic lesions in the liver showed shrinkage, we decided to switch regimens because of intolerable adverse events. A modified FOLFOX6 regimen with bevacizumab was administered as the second-line treatment. There were no signs of disease progression until eight months later, when positron emission tomography (PET)/CT scans revealed that the new metastatic lesions appeared. As the third-line treatment, an irinotecan with cetuximab regimen was administered, leading to a good response for over 12 months.
　We experienced a successful rechallenge with cetuximab for a case with metastatic rectal cancer. For patients with wild-type KRAS colorectal cancer, rechallenge with cetuximab-based chemotherapy can be an effective therapeutic option.

kn-abstract=　A 79-year-old woman visited a previous hospital with a complaint of general fatigue. The patient was diagnosed with cecal cancer with multiple liver metastases and lymph node metastases on colonoscopy, abdominal ultrasonography and CT scan, and was referred to our division for treatment. Based on the diagnosis of non-curative colonic cancer, we planned to perform systematic chemotherapy after local surgical treatment. We performed an ileocecal resection, and the specimen showed poorly differentiated adenocarcinoma with mutation in the BRAF oncogene. After the surgical treatment, the tumor grew rapidly and the patient died from cancer on the 19th postoperative day without having the opportunity to undergo chemotherapy.
　Multiple genetic and epigenetic alterations in oncogenes and tumor suppressor genes are involved in the process of colorectal carcinogenesis. Some of the alterations have been identified as predictive and prognostic biomarkers. A mutation in the BRAF oncogene was reported to be associated with a very unfavorable prognosis in colorectal cancers. Some of the cases with rapid progression are suggested to have the BRAF oncogene mutation. According to our experience, chemotherapy before surgical treatment might improve the prognosis of cases with the BRAF mutation.
