Recently, artificial intelligence (AI) has been used in endoscopic examination and is expected to help in endoscopic diagnosis. We evaluated the feasibility of AI using convolutional neural network (CNN) systems for evaluating the depth of invasion of early gastric cancer (EGC), based on endoscopic images.

Methods
This study used a deep CNN model, ResNet152. From patients who underwent treatment for EGC at our hospital between January 2012 and December 2016, we selected 100 consecutive patients with mucosal (M) cancers and 100 consecutive patients with cancers invading the submucosa (SM cancers). A total of 3508 non-magnifying endoscopic images of EGCs, including white-light imaging, linked color imaging, blue laser imaging-bright, and indigo-carmine dye contrast imaging, were included in this study. A total of 2288 images from 132 patients served as the development dataset, and 1220 images from 68 patients served as the testing dataset. Invasion depth was evaluated for each image and lesion. The majority vote was applied to lesion-based evaluation.

Results
The sensitivity, specificity, and accuracy for diagnosing M cancer were 84.9% (95% confidence interval [CI] 82.3%–87.5%), 70.7% (95% CI 66.8%–74.6%), and 78.9% (95% CI 76.6%–81.2%), respectively, for image-based evaluation, and 85.3% (95% CI 73.4%–97.2%), 82.4% (95% CI 69.5%–95.2%), and 83.8% (95% CI 75.1%–92.6%), respectively, for lesion-based evaluation.

Conclusions
The application of AI using CNN to evaluate the depth of invasion of EGCs based on endoscopic images is feasible, and it is worth investing more effort to put this new technology into practical use.

interferon-gamma- and IL-17A-producing lamina propria CD4(+) T cells through AMPK activation en-subtitle= kn-subtitle= en-abstract= kn-abstract= The herbal medicine berberine (BBR) has been recently shown to be an AMP-activated protein kinase (AMPK) productive activator with various properties that induce anti-inflammatory responses. We investigated the effects of BBR on the mechanisms of mucosal CD4+T cell activation in vitro and on the inflammatory responses in T cell transfer mouse models of inflammatory bowel disease (IBD). We examined the favorable effects of BBR in vitro, using lamina propria (LP) CD4+ T cells in T cell transfer IBD models in which SCID mice had been injected with CD4+CD45RBhigh T cells. BBR suppressed the frequency of IFN-γ- and Il-17A-producing LP CD4+ T cells. This effect was found to be regulated by AMPK activation possibly induced by oxidative phosphorylation inhibition. We then examined the effects of BBR on the same IBD models in vivo. BBR-fed mice showed AMPK activation in the LPCD4+ T cells and an improvement of colitis. Our study newly showed that the BBR-induced AMPK activation of mucosal CD4+ T cells resulted in an improvement of IBD and underscored the importance of AMPK activity in colonic inflammation.

en-title= kn-title=Clinicopathological Characteristics of Superficial Barrett's Adenocarcinoma in a Japanese Population: A Retrospective, Multicenter Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective Although Barrett's adenocarcinoma (BA) remains a minor disease in Japan, its incidence has been gradually increasing. We analyzed the characteristics of BA in Japanese populations.
Methods We retrospectively reviewed medical records and analyzed the clinicopathological differences between short-segment Barrett's esophagus (SSBE) and long-segment Barrett's esophagus (LSBE), as well as metastasis. Local recurrence and metachronous lesions were analyzed only in patients who underwent endoscopic resection (ER).
Patients Consecutive patients who had pathological T1 BAs resected by ER or surgery from January 2003
Results A total of 168 patients were analyzed, including 139 with SSBE and 29 with LSBE. In total, 67% of the SSBE lesions and 32% of the LSBE lesions were located between 0 and 3 o'clock (p=0.0014). No patients who achieved pathological margin-free resection (pR0) and 17% of patients who did not achieve pR0 experienced local recurrence (p=0.0131). None of the patients without lymphovascular involvement, a poorly differentiated component, lesion size of >30 mm, and submucosal invasion of >500 mu m experienced metastasis. The 5-year cumulative incidence rate of metachronous BA after ER was 0% in patients with SSBE and 40% in patients with LSBE (p=0.0005).
Conclusion Superficial BA was likely to be detected at the right anterior wall of SSBE in the Japanese population. The risk for metachronous BA after ER was high in Japanese patients with LSBE, as in Western patients. en-copyright= kn-copyright= en-aut-name=HamadaKenta en-aut-sei=Hamada en-aut-mei=Kenta

Endoscopic Submucosal Dissection under Heparin Replacement: A Retrospective Multicenter Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective Gastric endoscopic submucosal dissection (ESD) under heparin replacement (HR) of warfarin reportedly has a high risk of delayed bleeding (24-57%). It is possible that the delayed bleeding risk may have changed over the years. We evaluated the current risk of delayed bleeding after gastric ESD under HR of anticoagulant agents.
Methods We retrospectively reviewed the delayed bleeding rate and analyzed the risk factors for delayed bleeding.
Patients Consecutive patients who underwent gastric ESD under HR of anticoagulant agents from July 2015 to June 2017.
Results A total of 32 patients with a solitary early gastric cancer and taking anticoagulant agents were analyzed, including 24 patients on warfarin (the warfarin group) and 8 patients on direct oral anticoagulants (the DOAC group). Three (9.4%) patients experienced delayed bleeding: three (12.5%) patients in the warfarin group and no patients in the DOAC group. Continued aspirin treatment was identified to be a risk factor of delayed bleeding (p=0.01).
Conclusion Careful management may be required for patients undergoing gastric ESD under continued aspirin treatment in addition to HR of anticoagulant agents; although the delayed bleeding risk after gastric ESD under HR of anticoagulant agents might have decreased over the years. en-copyright= kn-copyright= en-aut-name=HamadaKenta en-aut-sei=Hamada en-aut-mei=Kenta kn-aut-name= kn-aut-sei=

kn-subtitle= en-abstract= kn-abstract=Determining factors that predict a favorable disease course without anti-tumor necrosis factor (TNF) agents would help establish a more cost-effective strategy for Crohn’s disease (CD). A retrospective chart review was performed for CD patients with disease durations > 10 years who had not received anti-TNF agents as first-line therapy. Patients were divided into 2 groups: those who received neither anti-TNF agents nor bowel resection (G1), and those who had received an anti-TNF agent and/or bowel resection (G2). The patient backgrounds, therapies and clinical courses were compared between the groups. A total of 62 CD patients met the inclusion criteria (males: 71%; median duration of follow-up: 19 years). Six patients were included in G1; they were significantly less likely to have upper gastrointestinal lesions than G2 (p=0.007). A multivariate analysis revealed that the significant factors for avoidance of bowel resection without anti-TNF treatment were non-stricturing and non-penetrating behaviors, and absence of upper gastrointestinal lesions at the diagnosis (hazard ratios 0.41 and 0.52; p=0.004 and 0.04, respectively). In consideration of the long treatment course of CD, patients with non-stricturing and non-penetrating behaviors and no upper gastrointestinal lesions should not be treated with anti-TNF agents as first-line therapy. en-copyright= kn-copyright= en-aut-name=InokuchiToshihiro en-aut-sei=Inokuchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiraokaSakiko en-aut-sei=Hiraoka en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YasutomiEriko en-aut-sei=Yasutomi en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkaShohei en-aut-sei=Oka en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamasakiYasushi en-aut-sei=Yamasaki en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KinugasaHideaki en-aut-sei=Kinugasa en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakaharMasahiro en-aut-sei=Takahar en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawanoSeiji en-aut-sei=Kawano en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HaradaKeita en-aut-sei=Harada en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KatoJun en-aut-sei=Kato en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=bDepartment of Gastroenterology, Mitsui Memorial Hospital kn-affil= en-keyword=Crohn’s disease kn-keyword=Crohn’s disease en-keyword=anti-TNF agent kn-keyword=anti-TNF agent en-keyword=upper gastrointestinal lesion kn-keyword=upper gastrointestinal lesion en-keyword=bamboo joint-like appearance kn-keyword=bamboo joint-like appearance END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=1 article-no= start-page=e83 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20211209 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Fever and electrocoagulation syndrome after colorectal endoscopic submucosal dissection for patients with immunosuppressants and steroids en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: Transient fever and electrocoagulation syndrome after colorectal endoscopic submucosal dissection (ESD) remain a challenge. The aim of this study was to assess the risk factors of post-ESD fever and post-ESD coagulation syndrome (PECS), focusing on the involvement of immunosuppressive drugs and steroids (IM).
Methods: This retrospective analysis included 510 patients who underwent colorectal ESD at Okayama University Hospital from 2015 to 2020. The incidence rate, clinical outcome, and factors associated with post-ESD fever and PECS were investigated.
Results: Post-ESD fever and PECS occurred in 63 patients (12.4%) and 43 patients (8.4%), respectively. In multivariate analysis, the American Society of Anesthesiologists Physical Status ≥3, the use of immunosuppressants or prednisolone ≥5mg (IM group), and injury to muscle layer/perforation were significantly associated with post-ESD fever. In PECS, IM group, tumors located on the right side, treatment time ≥60 min, injury to the muscle layer, and multiple lesions were independent risk factors. Both post-ESD fever and PECS improved conservatively in the IM group, and no serious complication was observed.
Conclusions: The use of IM was a risk factor for both post-ESD fever and PECS. However, there were no serious complications in colorectal ESD for patients taking IM. en-copyright= kn-copyright= en-aut-name=YamamotoShumpei en-aut-sei=Yamamoto en-aut-mei=Shumpei kn-aut-name=

disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Leucine-rich alpha-2 glycoprotein (LRG) may be a novel serum biomarker for patients with inflammatory bowel disease. The association of LRG with the endoscopic activity and predictability of mucosal healing (MH) was determined and compared with those of C-reactive protein (CRP) and fecal markers (fecal immunochemical test [FIT] and fecal calprotectin [Fcal]) in 166 ulcerative colitis (UC) and 56 Crohn's disease (CD) patients. In UC, LRG was correlated with the endoscopic activity and could predict MH, but the performance was not superior to that of fecal markers (areas under the curve [AUCs] for predicting MH: LRG: 0.61, CRP: 0.59, FIT: 0.75, and Fcal: 0.72). In CD, the performance of LRG was equivalent to that of CRP and Fcal (AUCs for predicting MH: LRG: 0.82, CRP: 0.82, FIT: 0.70, and Fcal: 0.88). LRG was able to discriminate patients with MH from those with endoscopic activity among UC and CD patients with normal CRP levels. LRG was associated with endoscopic activity and could predict MH in both UC and CD patients. It may be particularly useful in CD. en-copyright= kn-copyright= en-aut-name=YasutomiEriko en-aut-sei=Yasutomi en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

for patients with IBD-associated neoplasia en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
It is often difficult to diagnose inflammatory bowel disease (IBD)-associated neoplasia endoscopically due to background inflammation. In addition, due to the absence of sensitive tumor biomarkers, countermeasures against IBD-associated neoplasia are crucial. The purpose of this study is to develop a new diagnostic method through the application of liquid biopsy.
Methods
Ten patients with IBD-associated cancers and high-grade dysplasia (HGD) with preserved tumor tissue and blood were included. Tumor and non-tumor tissues were analyzed for 48 cancer-related genes using next-generation sequencing. Simultaneously, circulating tumor DNA (ctDNA) was analyzed for mutations in the target genes using digital PCR.
Results
Out of 10 patients, seven had IBD-related cancer and three had IBD-related HGD. Two patients had carcinoma in situ; moreover, three had stageII and two had stage III. To avoid false positives, the mutation rate cutoff was set at 5% based on the control results; seven of 10 (70%) tumor tissue samples were mutation-positive. Mutation frequencies for each gene were as follows: TP53 (20.9%; R136H), TP53 (25.0%; C110W), TP53 (8.5%; H140Q), TP53 (31.1%; R150W), TP53 (12.8%; R141H), KRAS (40.0%; G12V), and PIK3CA (34.1%; R 88Q). The same mutations were detected in the blood of these seven patients. However, no mutations were detected in the blood of the remaining three patients with no tumor tissue mutations. The concordance rate between tumor tissue DNA and blood ctDNA was 100%.
Conclusion
Blood liquid biopsy has the potential to be a new method for non-invasive diagnosis of IBD-associated neoplasia. en-copyright= kn-copyright= en-aut-name=KinugasaHideaki en-aut-sei=Kinugasa

en-subtitle= kn-subtitle= en-abstract= kn-abstract=Although the clinical usefulness of colonoscopy has been established, the procedure remains painful for many patients. This study was designed to clarify the factors predicting colonoscopy-related pain. We evaluated 283 consecutive patients who completed a first-ever, total colonoscopy without sedatives or analgesics. The severity of pain symptoms was evaluated by a numeric rating scale (NRS) in a questionnaire immediately after the colonoscopy. Patient backgrounds and endoscopic findings were analyzed to evaluate their association with pain. Out of 283 patients, 53 scored their pain 0-1 on the NRS while 48 scored it 6-10. We defined the colonoscopies of the former and latter patients as painless and painful, respectively, and compared the two. Multivariate analyses revealed that low body weight (OR 4.95, 95%CI 1.89-12.99) and longer intubation time (OR 3.63, 95%CI 1.46-9.03) were significant risk factors for painful colonoscopy. To identify factors contributing to the increased intubation time, we divided subjects into short- and long-intubation-time groups based on a median insertion time of 7 min. Older age (OR 2.28, 95%CI 1.31-3.98), previous abdominal surgery (OR 1.93, 95%CI 1.13-3.32) and findings of invasive cancer (OR 10.90, 95%CI 1.34-88.90) were significant factors for longer intubation time. en-copyright= kn-copyright= en-aut-name=OkaShohei en-aut-sei=Oka en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HaradaKeita en-aut-sei=Harada en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamamotoShumpei en-aut-sei=Yamamoto en-aut-mei=Shumpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YasutomiEriko en-aut-sei=Yasutomi en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IgawaShoko en-aut-sei=Igawa en-aut-mei=Shoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OhmoriMasayasu en-aut-sei=Ohmori en-aut-mei=Masayasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HiraiMami en-aut-sei=Hirai en-aut-mei=Mami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamasakiYasushi en-aut-sei=Yamasaki en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=InokuchiToshihiro en-aut-sei=Inokuchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KinugasaHideaki en-aut-sei=Kinugasa en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TakaharaMasahiro en-aut-sei=Takahara en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HiraokaSakiko en-aut-sei=Hiraoka en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=colonoscopy kn-keyword=colonoscopy en-keyword=colonoscopy-related pain kn-keyword=colonoscopy-related pain en-keyword=comfortable colonoscopy kn-keyword=comfortable colonoscopy END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=05 article-no= start-page=E609 end-page=E615 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220513 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Modified line-assisted complete closure of the defect after gastric endoscopic full-thickness resection: a pilot study in porcine models en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and study aims Closure after endoscopic full-thickness resection (EFTR) is challenging. We previously developed a simple endoscopic closure method: line-assisted complete closure (LACC). We performed a pilot study using porcine models to evaluate the feasibility of modified LACC after gastric EFTR.
Patients and methods Six live pigs were included. EFTR (greater curvature of the gastric antrum [n = 3] and anterior wall of the gastric body [n = 3]) was performed under general anesthesia and the defect after EFTR was closed by modified LACC. The pigs were observed until postoperative day 4 (Day 4). The closure site was endoscopically evaluated and the presence or absence of peritonitis and fluid leakage was evaluated. The outcomes were the success rate of modified LACC on the day of the procedure, maintenance of defect closure, presence of peritonitis or leakage, and clinical course.
Results Once complete closure was successfully achieved in all cases, maintenance of closure on Day 4 was not achieved. However, there was neither peritonitis nor fluid leakage. The defect was completely covered by surrounding tissues on Day 4 and the clinical course was good in all cases.
Conclusions The feasibility of modified LACC after gastric EFTR was demonstrated in porcine models. Further improvement is needed to maintain defect closure. en-copyright= kn-copyright= en-aut-name=YamasakiYasushi en-aut-sei=Yamasaki en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OhmoriMasayasu en-aut-sei=Ohmori en-aut-mei=Masayasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ToyosawaJunki en-aut-sei=Toyosawa en-aut-mei=Junki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AkoSoichiro en-aut-sei=Ako en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=2 en-affil=DDepartment of Gastroenterology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=4 article-no= start-page=3076 end-page=3080 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200221 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Observer agreement for the diagnosis of intestinal acute graft‑vs.‑host disease based on the presence of villous atrophy in the terminal ileum en-subtitle= kn-subtitle= en-abstract= kn-abstract=Intestinal graft‑vs.‑host disease (GVHD) is a serious complication of allo‑hematopoietic stem cell transplantation (allo‑HSCT). Villous atrophy in the terminal ileum is considered a useful diagnostic indicator for GVHD. However, the inter‑ and intra‑observer agreement regarding the ileocolonoscopic findings indicative of acute intestinal GVHD, i.e., villous atrophy in the terminal ileum, are currently insufficient in multiple institutions. Thus, the present study aimed to investigate the incidence of villous atrophy in the terminal ileum to diagnose acute intestinal GVHD and determine the inter‑ and intra‑observer agreement regarding this result for experienced endoscopists from multiple institutions. Consecutive patients who underwent allo‑HSCT were referred to our institution between May 2008 and September 2015. A total of 54 patients underwent total ileocolonoscopy after allo‑HSCT due to suspected intestinal acute GVHD. Subsequently, three observers from different institutions evaluated the cases for the presence of villous atrophy in the terminal ileum. In this study, the pathology results were a gold standard to evaluate the predictive value of ileocolonoscopy detection. Definitive pathological and non‑pathological GVHD was diagnosed in 22 and 32 cases, respectively. The results of examining whether villous atrophy could predict GVHD were as follows. For three observers (A, B and C), the sensitivity of villous atrophy in the terminal ileum was 86.4, 77.3 and 79.2%, respectively, whereas the specificity was 62.5, 62.5 and 86.7%, respectively. The positive predictive value (PPV) and negative predictive value (NPV) of villous atrophy for GVHD were as follows: The PPV of appearance was 61.3, 58.6 and 82.6%, respectively, whereas the NPV was 87.0, 80.0 and 83.9%, respectively. Kappa coefficients for the inter‑observer reliability were 0.85, 0.63 and 0.63 for observers A and B, A and C, and B and C, respectively. The intra‑observer kappa coefficient was 0.88 for observer A, 0.73 for observer B and 0.75 for observer C. A substantial observer agreement was achieved for the analysis of villous atrophy in the terminal ileum and the agreement for the predictive histological diagnosis was also excellent. Based on the results of the present study, identification of villous atrophy in the terminal ileum was a clinically effective diagnostic parameter, even if different endoscopists were involved in the diagnosis at multiple institutions. The present study was registered as a trial with the University Hospital Medical Information Network (UMIN; registration no.

This was a multicenter prospective trial evaluating the efficacy and safety of cold forceps polypectomy (CFP) for diminutive NADAs.
Patients and methods　This study was prospectively conducted at six general hospitals and one university hospital. The inclusion criteria were histologic and endoscopic diagnosis of low-grade NADA measuring ≤ 6 mm. A second endoscopy was scheduled for 1 month after CFP. After confirmation of the success of CFP, 6-month and 12-month surveillance endoscopies were scheduled. The primary endpoint was the endoscopic and histologic disease disappearance rates at the 12-month endoscopy.
Results　Thirty-nine lesions from 38 patients were prospectively included. Median tumor size at enrollment was 5 mm (range 3–6 mm). There were four cases of remnant lesions at the second endoscopy, and the lesion disappearance rate of single CFP was 89.7 % (35 /39; 95 % confidence interval (CI), 76.9 %–97.9 %). In three cases, complete removal of the lesion was achieved with a single re-CFP, but one case required four repeat CFPs. The lesion disappearance rate at 12-month endoscopy was 97.4 % (38 /39; 95 %CI, 86.8 %–99.5 %). During the follow-up period, no AEs related to CFP were observed.
Conclusions　CFP for NADA ≤ 6 mm was safe and effective in this study. This common endoscopic method to remove lesions may be an option for treatment of diminutive NADAs. en-copyright= kn-copyright= en-aut-name=KanzakiHiromitsu en-aut-sei=Kanzaki en-aut-mei=Hiromitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HoriiJoichiro en-aut-sei=Horii en-aut-mei=Joichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakenakaRyuta en-aut-sei=Takenaka en-aut-mei=Ryuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakagawaHiroyuki en-aut-sei=Nakagawa en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsuedaKazuhiro en-aut-sei=Matsueda en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TsuzukiTakao en-aut-sei=Tsuzuki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KitaMasahide en-aut-sei=Kita en-aut-mei=Masahide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamasakiYasushi en-aut-sei=Yamasaki en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KawanoSeiji en-aut-sei=Kawano en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KawaharaYoshiro en-aut-sei=Kawahara en-aut-mei=Yoshiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=TomodaJun en-aut-sei=Tomoda en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterology, Fukuyama Medical Center kn-affil= affil-num=3 en-affil=Department of Internal Medicine, Tsuyama Central Hospital kn-affil= affil-num=4 en-affil=Department of Endoscopy, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Kurashiki Central Hospital kn-affil= affil-num=6 en-affil=Department of Internal Medicine, Himeji Red Cross Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterology, Okayama City Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Practical Gastrointestinal Endoscopy, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Internal Medicine, Akaiwa Medical Association Hospital kn-affil= affil-num=14 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=05 article-no= start-page=E602 end-page=E608 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220513 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Resection depth for small colorectal polyps comparing cold snare polypectomy, hot snare polypectomy and underwater endoscopic mucosal resection en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and study aims Small colorectal polyps are removed by various methods, including cold snare polypectomy (CSP), hot snare polypectomy (HSP), and underwater endoscopic mucosal resection (UEMR), but the indications for using these methods are unclear. We retrospectively assessed the efficacy of CSP, HSP, and UEMR for small polyps, focusing on the depth of the resected specimens.
Patients and methods Outpatients with non-pedunculated small polyps (endoscopically diagnosed as 6 to 9 mm), resected by two endoscopists between July 2019 and September 2020, were enrolled. We histologically evaluated the specimens resected via CSP, HSP, and UEMR. The main outcome was the containment rate of the muscularis mucosa (MM) and submucosa (SM) tissues.
Results Forty polyps resected via CSP (n = 14), HSP (n = 12), or UEMR (n = 14) were enrolled after excluding 13 polyps with resection depths that were difficult to determine. The rates of specimens containing MM and SM tissue differed significantly (57 % and 29 % for CSP, 92 % and 83 % for HSP, and 100 % and 100 % for UEMR, respectively (P = 0.005 for MM and P < 0.001 for SM tissue). Multiple logistic regression analysis showed UEMR was an independent factor relating to the containment of SM tissue. The thickness of SM tissue by CSP, HSP, and UEMR were 52 μm, 623 μm, and 1119 μm, respectively (P < 0.001). The thickness by CSP was significantly less than those by HSP and UEMR (P < 0.001, Bonferroni correction).
Conclusions UEMR could be the best method to contain SM tissue without injection. Further studies are needed to evaluate the indication of UEMR for small polyps. en-copyright= kn-copyright= en-aut-name=ToyosawaJunki en-aut-sei=Toyosawa en-aut-mei=Junki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamasakiYasushi en-aut-sei=Yamasaki en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujimotoTsuyoshi en-aut-sei=Fujimoto en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaShouichi en-aut-sei=Tanaka en-aut-mei=Shouichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterology, Iwakuni Clinical Center kn-affil= affil-num=4 en-affil=Department of Gastroenterology, Iwakuni Clinical Center kn-affil= affil-num=5 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue=18 article-no= start-page=2703 end-page=2709 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220915 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Colon Wall Thickness Measured Using Transabdominal Ultrasonography Is Useful for Detecting Mucosal Inflammation in Ulcerative Colitis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective Transabdominal ultrasonography (TUS) is a non-invasive procedure that is reportedly useful for managing ulcerative colitis (UC) and assessing bowel wall thickness (BWT), the most common measure of mucosal inflammation. However, the exact range of BWT that reflects disease activity remains undetermined. The present study clarified the BWT due to disease activity by comparing the use of TUS in each segment of the colon versus using colonoscopy (CS) and determined the usefulness of TUS in patients with UC.Methods We divided the colon into five segments and measured the BWT using TUS. The results were then compared to the Mayo endoscopic subscore (MES) classification to determine the accuracy of BWT measurement.Patients Eighty patients with UC who underwent TUS within 14 days of CS were retrospectively regis-tered.Results We evaluated a total of 268 images depicting each segment among 80 patients with UC. The BWT was positively correlated with endoscopic activity (0.69, p<0.0001). In each segment, the relationship be-tween a BWT>2 mm and an MES>0 had the highest sensitivity, specificity, and accuracy (0.85-1.00, 0.67-0.92, and 0.81-0.97, respectively).Conclusion This study concluded that TUS was a useful method of detecting an MES>0, which indicates the presence of inflammation and its location among UC patients. MES>0 was found to be highly accurate when a BWT>2 mm was considered positive. This non-invasive method may help control disease activity in patients with UC. en-copyright= kn-copyright= en-aut-name=TakaharaMasahiro en-aut-sei=Takahara en-aut-mei=Masahiro kn-aut-name=

kn-title=The Impact of KRAS Mutation in Patients With Sporadic Nonampullary Duodenal Epithelial Tumors en-subtitle= kn-subtitle= en-abstract= kn-abstract=INTRODUCTION: The genomic characterization of primary nonampullary duodenal adenocarcinoma indicates a genetic resemblance to gastric and colorectal cancers. However, a correlation between the clinical and molecular characteristics of these cancers has not been established. This study aimed to elucidate the clinicopathological features of sporadic nonampullary duodenal epithelial tumors, including their molecular characteristics and prognostic factors.
METHODS: One hundred forty-eight patients with sporadic nonampullary duodenal epithelial tumors were examined in this study. Patient sex, age, TNM stage, tumor location, treatment methods, histology, KRAS mutation, BRAF mutation, Fusobacterium nucleatum, mucin phenotype, and programmed death-ligand 1 (PD-L1) status were evaluated. KRAS and BRAF mutations, Fusobacterium nucleatum, mucin phenotype, and PD-L1 status were analyzed by direct sequencing, quantitative polymerase chain reaction, and immunochemical staining.
RESULTS: The median follow-up duration was 119.4 months. There were no deaths from duodenal adenoma (the primary disease). Kaplan-Meier analysis for duodenal adenocarcinoma showed a significant effect of TNM stage (P < 0.01). In univariate analysis of primary deaths from duodenal adenocarcinoma, TNM stage II or higher, undifferentiated, KRAS mutations, gastric phenotype, intestinal phenotype, and PD-L1 status were significant factors. In multivariate analysis, TNM stage II or higher (hazard ratio: 1.63 x 10(10), 95% confidence interval: 18.66-6.69 x 10(36)) and KRAS mutation (hazard ratio: 3.49, confidence interval: 1.52-7.91) were significant factors.
DISCUSSION: Only KRAS mutation was a significant prognostic factor in primary sporadic nonampullary duodenal adenocarcinoma in cases in which TNM stage was considered. en-copyright= kn-copyright= en-aut-name=KinugasaHideaki en-aut-sei=Kinugasa en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KanzakiHiromitsu en-aut-sei=Kanzaki en-aut-mei=Hiromitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamotoShumpei en-aut-sei=Yamamoto en-aut-mei=Shumpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamasakiYasushi en-aut-sei=Yamasaki en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NousoKazuhiro en-aut-sei=Nouso en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IchimuraKouichi en-aut-sei=Ichimura en-aut-mei=Kouichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakagawaMasahiro en-aut-sei=Nakagawa en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Pathology, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=8 en-affil=Department of Endoscopy, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=9 en-affil=Center for Innovative Clinical Medicine, OkayamaUniversity Hospital kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=1 article-no= start-page=79 end-page=83 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Utility of Combined Use of Transabdominal Ultrasonography and Fecal Immunochemical Test Examinations in Ulcerative Colitis en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study examined the utility of the combined use of transabdominal ultrasonography (TUS) and fecal immunochemical testing (FIT) to detect mucosal inflammation, vis-a-vis the Mayo endoscopic subscore (MES), in ulcerative colitis (UC).
