| Abstract | Laparoscopic repair of a suprapubic hernia typically carries a high risk of recurrence, because fixation of the mesh in the peripubic area is difficult. We herein report a patient undergoing laparoscopic repair of a suprapubic hernia, along with a description of the surgical techniques employed. A 78-year-old woman visited our hospital with a chief complaint of swelling at the median hypogastric incision site after surgery for an ovarian cyst performed at age 25 years. Laparoscopic examination revealed the hernia orifice to be 3.5×3.0 cm in size and that the distance between the caudal margin of the hernia orifice and the pubis was 2.5 cm. Parietex composite mesh was used for fixation through all layers of the abdominal wall with non-absorbable sutures and tack fixation. On the pubic side, after the pubis had been exposed by separating it from the bladder, we performed mesh fixation through all layers of the abdominal wall immediately above the pubis with the sutures placed inside the mesh, combined with tack mesh fixation directly to the pubis. This procedure enabled definite fixation of the mesh. Six days after surgery, she was discharged without complications. To date, two years and five months after surgery, no recurrence has been observed. |

| Abstract | A 49-year-old Japanese man visited our hospital with chief complaints of difficulty with and bleeding during defecation. After a detailed examination, he was diagnosed with familial adenomatous polyposis (FAP) with multiple (five) colorectal cancers. The tumors were located in the right-sided, left-sided, and sigmoid colon, and the lower rectum. Regional lymph node involvement was observed, but no metastasis to other organs was detected. We, therefore, performed a laparoscopic total colectomy with superior mesenteric artery (SMA) and inferior mesenteric artery (IMA) lymph node dissection. We were able to perform minimally invasive and cosmetically acceptable surgery using laparoscopy instead of highly-invasive open abdominal surgery. Our search of the literature revealed no reported cases of laparoscopic total colectomy with lymph node dissection for FAP with multiple colorectal cancers, making the present case the first to be reported in the literature. |

| Abstract | Zenker's diverticulum is a very rare disease among gastorointestinal diverticulum. We report a case of Zenker's diverticulum successfully treated with diverticulectomy and cricophalyngial myotomy. A 71-year-old male complained of aspirating water for two years. He was diagnosed as Zenker's diverticulum. Due to his severe symptoms, the operation was performed in an open-neck approach. The left recurrent laryngeal nerve was identified and preserved. An incision was made in the diverticulum wall, and the internal diameter of normal cervical esophagus was measured. The diverticulum was then excised with an automatic suture device in the minor axis direction of the esophagus. A cricopharyngeal myotomy was conducted, because this muscle was fibrotic and stiffened. The patient's symptoms disappeared after the operation. Diverticulectomy and cricopharyngeal myotomy through an open-neck approach is a safe and reliable method that follows, direct access to the diverticulum and recurrent laryngeal nerve. |

| Title Alternative | Precipitation characteristics and large-scale atmospheric fields on the heavy rainfall days in the eastern part of Japan (Climatological features in midsummer and the supplemental study for the Baiu season) |

| Abstract | Rainfall characteristics and large-scale atmospheric fields on the “heavy rainfall days” (with more than 50mm/day) in midsummer, and so on, at Tokyo in the eastern Japan were examined for 1971 to 2010, succeeding to Matsumoto et al. (2013) The present study firstly examined the rainfall features and the atmospheric fields for the “heavy rainfall days” at Tokyo with rather lower appearance frequency than in the typhoon related patterns in Matsumoto et al. (2013) and so on. In these cases (three cases in total), although the synoptic situations were rather different among each other, they seem to occur under the systems with relatively small zonal scale associated with the great meander of the upper-level westerly wind. Next, the climatological analyses similar to Matsumoto et al. (2013) were performed for the "heavy rain days" at Tokyo in midsummer (1~31 August). The precipitation on the “heavy rainfall days” at Tokyo in midsummer was mainly brought by the intense rainfall with more than 10 mm/h, as in the western Japan in the mature stage of the Baiu season. The detailed examination of the rainfall features for the case on 10 August 2009, with use of the 10-minutes precipitation data and the Radar AMeDAS Composite Data by the JMA, revealed that the organized meso-β-scale convective rainfall systems as often appear in the western Japan in the mature stage of the Baiu season were just to the east of the typhoon, and brought the intense rainfall at Tokyo to result in the large daily precipitation. |

| Abstract | Inflammatory myofibroblastic tumor (IMT) is a rare neoplasm that occurs at different sites in the body. Pleural IMT in particular is especially rare. IMTs infrequently tend to have malignancy. We report a rare case of advanced diaphragmatic parietal pleural IMT with dissemination. A 30-year-old woman complained of right upper abdominal pain. Computed tomography showed a large lobulated mass over the right diaphragm, but no disseminated nodules were noted. Intraoperatively, we found the primary tumor arising from the diaphragmatic parietal pleura and a dozen disseminated nodules, and we removed them completely. The histopathological and immunohistochemical diagnosis was IMT. |

| Abstract | Roughly half of the femoral fracture patients diagnosed with AFF according to the criteria suggested by a task force of the American Society for Bone and Mineral Research (ASBMR) have not undergone bisphosphonate (BP) therapy. One suspected cause of such fractures is severe bone loss due to osteomalacia, but the pathogenesis remains unknown. We report a case of an 84-year-old woman with AFF not treated by BP therapy, in whom underlying osteomalacia was histologically diagnosed. The involvement of femoral curvature and spino-pelvic malaligment in the fracture in the present case was considered. |

| Abstract | We report a case of POEMS syndrome in a 20-year-old patient diagnosed after visiting an eye clinic with a chief complaint of reduced visual acuity. A male university student aged 20 years was referred to our department complaining of blurred vision in both eyes that had persisted for 1 month. He also noted headache, nausea, and paresthesia in the lower extremities around the same time. The visual acuity of his right and left eye was 20/40 and 20/20, respectively. Optic disc edema and serous retinal detachment were present. Brain magnetic resonance imaging showed no intracranial abnormalities, while elevated cerebrospinal fluid pressure, reduced nerve conduction velocity in both lower extremities, hepatosplenomegaly, M proteinemia, high blood VEGF levels, osteoblastic and osteolytic changes in the spine, and atypical plasma cells in bone lesions were noted. From the above findings, the patient was diagnosed with POEMS syndrome. He received high-dose dexamethasone, thalidomide, and radiotherapy on the sacral mass, followed by high-dose melphalan with autologous stem-cell support, and showed subsequent systemic and ophthalmologic improvement. Here, we report the youngest case ever of POEMS syndrome with ocular manifestation. If patients have optic disc edema in both eyes with no intracranial space-occupying lesion, POEMS syndrome should be considered in differential diagnosis, regardless of age. |

| Abstract | We encountered a 74-year-old male patient with tongue laceration after convulsive seizures under intensive care. The tongue showed severe swelling, and the right ventral surface had been lacerated by his isolated and pointed right lower canine. Our university hospital has established a perioperative management center, and is promoting interprofessional collaboration, including dentists, in perioperative management. Dentists collaborating in the perioperative management center took dental impressions, with the support of anesthesiologists who opened the patientʼs jaw under propofol sedation, to produce a mouth protector. By raising the patientʼs bite, the completed mouth protector prevented the isolated tooth from contacting the tongue and protected the lacerated wound. Use of the mouth protector prevented the lacerated tongue from coming into contact with the pointed tooth, and the tongue healed gradually. These findings underscore that interprofessional collaboration including dentists can improve the quality of medical care. |

| Abstract | A 67-year-old Japanese man underwent enterotomy because of enterolith ileus. Component analysis by infrared spectroscopy revealed that the enterolith was composed of a high concentration of deoxycholic acid. We further analyzed and compared the ultrastructure of the enterolith and a commercially available powdered form of deoxycholic acid by means of scanning electron microscopy and energy dispersive X-ray spectroscopy. Energy dispersive X-ray spectroscopy analysis revealed that the ratios of carbon and oxygen in the enterolith were equal to those in the deoxycholic acid powder. Scanning electron microscopy analysis showed rectangular prism-shaped particles on the surface of the enterolith. This structure was similar to that of the deoxycholic acid powder. The surgically removed enterolith had a twisted and coiled appearance. Possible mechanisms underlying the formation of this unique form are discussed. |

| Abstract | Leukocytosis is occasionally seen in patients with presumptive but undiagnosed myeloproliferative disorders (MPD). A 74-year-old woman was admitted to our hospital for tarry stools, anemia, and marked peripheral leukocytosis of 1.4×105/μL. Gastroenteroscopy revealed an acute gastric and duodenal mucosal lesion that was treated successfully via endoscopic hemoclipping. Bone marrow aspiration revealed marked megakaryocyte proliferation with atypia of naked nuclei and marrow hypercellularity (90% cellularity). A fluorescence in situ hybridization test could not detect the BCR-ABL fusion gene. Bone marrow aspiration later revealed further abnormalities of megakaryocytes. The patient died from cerebral bleeding. The present case fulfilled 2 of the 3 major criteria of primary myelofibrosis according to the World Health Organization 2008 classification:namely, megakaryocytic hyperplasia with hypercellular marrow and granulocytic hyperplasia. However, the megakaryocytic abnormality was not strictly compatible with the criteria. Instead, we considered prefibrotic primary myelofibrosis as a possibility, although myelodysplastic syndrome/myeloproliferative neoplasm, unclassifiable (MDS/MPN-U) was technically the correct diagnosis. The present case shows that MPN diagnosis remains difficult and suggests that other cases of peripheral leukocytosis with diagnosed MDS/MPN-U might include similar findings. |

| Abstract | Appendicitis is a benign disease for which surgical treatment is widely provided. The complication of neoplastic lesions may be discovered only after resection. However, in some cases, specimens are not submitted to histopathological examination in Japan because of an extreme deficiency of pathologists. We report our experience with one patient who experienced the complication of latent low-grade appendiceal mucinous neoplasm (LAMN) after surgery for appendicitis. Our patient was an 85-year-old woman. Conservative treatment failed to relieve fever and lower abdominal pain and it was decided to treat her surgically. Abdominal computed tomography (CT) showed appendicitis with severe inflammation and suspected adhesion. We decided to explore the abdominal cavity using a reduced-port laparoscopic approach. We found no mucous debouchment or clear tumors in the specimen. Histopathological findings indicated the coexistence of appendicitis and LAMN. At one year and a half after surgery, there was no evidence of the development of pseudomyxoma peritonei. In appendectomy, it is thought that careful perioperative treatment and a postoperative pathological search are important when there are no preoperative findings suggesting a neoplastic lesion. |

| Abstract | We report a case of giant rectal gastrointestinal stromal tumor (GIST) successfully resected by abdominoperineal resection combined with posterior vaginal wall resection. Our patient was a 79-year-old woman had been diagnosed as having von Recklinghausen disease at the age of 30 years. In 2006, a computed tomography (CT) scan revealed a tumor originating from the posterior wall of the rectum. In June 2010, she was admitted to our hospital with the chief complaint of bloody stool. A CT scan revealed a giant tumor that had increased to 9cm in size. Colonoscopy demonstrated a submucosal tumor, which was subsequently diagnosed by biopsy as a GIST. Due to the patient's continuous bleeding and abdominal pain, an emergent abdominoperineal resection was performed at that time. The tumor, which measured 8×9cm, was immunohistochemically positive for c-kit and CD34. Concomitant resection of the posterior wall of the vagina via the perineal approach provided a wide area to expose the tumor for a safe operation. The patient has been well with no sign of recurrence since the operation. This procedure is recommended as a useful approach for giant rectal GISTs or rectal cancer with invasion of the posterior pelvic wall. |

| Abstract | Ossified meningioma is classified histologically as a phenotype of metaplastic meningioma, and it is extremely rare. There are only 12 cases involving ossified spinal meningiomas in the literature. We present the case of a 61-year-old female with a primary tumor within the ventral spinal canal at T12. Although we performed a total tumor excision using an ultrasonic bone aspirator, a temporary deterioration of motor evoked potentials (MEPs) was observed during curettage with a Kerrison rongeur. The neurologic findings worsened immediately after surgery. Histologically, the tumor was diagnosed as a metaplastic meningioma with osseous differentiation. In order to avoid spinal cord injury, great care must be taken when removing an ossified meningioma located on the ventral spinal cord. |

| Abstract | A 45-year-old female who presented with loss of consciousness and a cold sweat was found to have a pancreatic tumor and multiple liver metastases. Laboratory studies showed marked hypoglycemia and inappropriately elevated serum insulin, C-peptide, and serum tumor markers. Fine needle aspiration revealed Grade 3 small-cell type primary pancreatic neuroendocrine carcinoma. Consequently, the diagnosis of malignant insulinoma was made. Transarterial embolization (TAE) for hepatic metastases resulted in the reduction of tumor volume and prompt resolution of hypoglycemic attacks, whereas diazoxide and systemic chemotherapy had been ineffective for controlling blood glucose levels, and octreotide was unavailable due to the allergic effect. This case report highlights the potential usefulness of TAE for malignant insulinomas in the management of hypoglycemia. |

| Abstract | Spinal deformity is an important clinical manifestation of Chiari I malformation (CM-I) and syringomyelia. Here we report the result of an 8-year follow-up of a 13-year-old girl with severe scoliosis associated with Chiari malformation and a large syringomyelia. The patient presented at our hospital at the age of 13 with a 68° scoliosis. Magnetic resonance imaging showed Chiari malformation and a large syringomyelia. Neurosurgical treatment involved foramen magnum decompression and partial C1 laminectomy, but the scoliosis still progressed. We present the first case report of a rare course of scoliosis in a patient with CM-I and a large syringomyelia. |

| Abstract | We describe an extremely rare case of tracheal stenosis caused by unnoticed microscopic fiber-like foreign bodies. A 66-year-old woman complained of dyspnea with inspiratory stridor. Magnifying electroendoscopy and computed tomography revealed stenosis involving the entire circumference of the tracheal lumen. Tracheotomy and biopsy were performed. Histologically, the lesion showed chronic inflammation with a deposition of fiber-like foreign bodies. The patient had no history of trauma or inhalation injury, but had undergone intratracheal intubation on 4 occasions. The lesion was incised using semiconductor laser photoresection, and the postoperative course was good. To the best of our knowledge, this represents the first report in the English literature of tracheal stenosis caused by unnoticed foreign bodies. The origin of these fiber-like foreign bodies remains unclear but might be related to chronic inflammation resulting from intratracheal intubations. |

| Abstract | We encountered a patient with an adult Bochdalek hernia discovered asymptomatically. A 77-year-old Japanese woman visited a local clinic with chief complaints of melena and difficulty in defecation. Based on the results of the detailed examination in our hospital, she was diagnosed with a rectal gastrointestinal stromal tumor (GIST) with a concurrent asymptomatic adult right-sided Bochdalek hernia. Because the tumor was large, laparoscopic abdominoperineal rectal amputation was performed after systemic imatinib therapy. During the surgery, we found a right diaphragmatic defect more than 13cm in long dia., through which the right hepatic lobe, colon, and greater omentum had prolapsed into the right thoracic cavity. No visceral adhesions were noted. No hernia sac was observed. Adult Bochdalek hernia is a relatively rare condition, and only three (incidentally discovered) cases of asymptomatic Bochdalek hernia, including the present case, have been reported in Japan. Here we provide a case report for the patient, who was followed-up without hernia surgery, plus a review of the literature. |
