    In our series of 366 patients who received intensity-modulated radiation therapy (IMRT) for prostate cancer, radiation proctitis developed in 24 patients. We examined the endoscopic evidence and clinical characteristics of radiation proctitis in these patients. The onset time was 2-29 months after treatment, with bloody bowel discharge being the most common symptom (22 cases). Colonoscopy revealed that the lesions tended to be concentrated on the rectal right anterior wall. Severity, according to the Tada classification, was 0b or Ia in 70.8% of all cases. The incidence of radiation proctitis decreased, and the clinical and endoscopic findings showed only mild radiation proctitis after IMRT.

    We report a case of a woman in her twenties with enterohemorrhagic Escherichia coli O111-induced hemolytic-uremic syndrome who developed acute encephalopathy on day 5 of admission. She recovered after treatment with steroid pulse therapy, plasmapheresis, and recombinant thrombomodulin, without any adverse sequelae. We report this interesting case and provide a summary of the recent outbreak of enterohemorrhagic Escherichia coli O111.

    We report our experiences of a case of repeated bleeding after hemorrhoid ligation. A 53-year-old man underwent hemorrhoid ligation for internal hemorrhoids at another hospital. Postoperatively, he developed severe and repeated bleeding. Scanning revealed extrahepatic portal venous obstruction. The severe bleeding persisted after transfer to our institution, where we re-sutured the ligature and performed superior rectal artery embolism, leading to arrest of bleeding. The rectal varix arose due to portal hypertension, which resulted in the diagnosis of idiopathic extrahepatic portal vein obstruction.

  • A case of asymptomatic Sjögren's syndrome who developed interstitial pneumonia during monoclonal antibody therapy of Crohn's disease

    A 67-year-old woman was diagnosed with ileocolic Crohn's disease at 61 years of age. Remission had been induced by the monoclonal antibody adalimumab, and maintenance therapy had continued since her diagnosis. However, she developed respiratory symptoms, including a dry cough. A chest CT scan revealed interstitial shadows in the lower pulmonary lobes. Although no sicca symptoms were noted, she was serologically positive for both anti-Sjögren's syndrome-related antigen A and B antibodies, and salivary gland biopsy showed lymphocytic infiltration. Consequently, she was diagnosed as having asymptomatic Sjögren's syndrome. Infection or drug-induced pulmonary disease was considered unlikely, and the interstitial pneumonia was considered an extra-glandular presentation of Sjögren's syndrome. Thus, interstitial shadows, which appear during immunotherapy for Crohn's disease, could indicate asymptomatic Sjögren's syndrome; clinicians should consider this rare clinical picture when assessing such a patient.

    A 54-year-old woman exhibited pancreatic calcification on abdominal ultrasonography. Diagnostic imaging revealed a 20-mm mass with a 12-mm calcification in the tail of the pancreas. The mass was weakly enhanced in the early phase of contrast-enhanced CT. We performed pancreatectomy and splenectomy. Histopathological diagnosis was a nonfunctioning pancreatic neuroendocrine tumor (PNET), grade 2. This is a rare case of PNET with extensive calcification.

    A 42-year-old man working at a printing company was referred to our hospital for examination and treatment of icterus. We diagnosed resectable hilar cholangiocarcinoma and provided neoadjuvant chemoradiotherapy, extended right hepatectomy, and extrahepatic bile duct resection. A detailed history revealed that he had used 1,2-dichloropropane as part of his work as an offset colour proof-printer, and he has subsequently been recognized as having occupational cholangiocarcinoma. He has survived without recurrence for more than 2 and half years since the liver resection. In the present report, we describe our valuable experience of neoadjuvant chemoradiotherapy for occupational cholangiocarcinoma.

    A 65-year-old woman was suspected of having advanced gallbladder cancer based on imaging results. This was considered inoperable because it was accompanied by possible liver metastasis. To confirm the diagnosis prior to chemotherapy, endoscopic transpapillary catheterization in the gallbladder (ETCG) was performed. The bile cytology was analyzed by the cell block method, which revealed mixed adenoneuroendocrine carcinoma. Based on the cytological results, extended cholecystectomy and partial hepatectomy were performed for the metastatic lesions. Bile cytology by ETCG with the cell block method was useful for deciding the therapeutic strategy in this patient with metastatic gallbladder cancer.

    We present a case of resected mucinous cystic neoplasm of the liver in a 71-year-old woman admitted to our hospital with epigastric discomfort. Abdominal ultrasonography and computed tomography revealed a multi-locular cystic tumor measuring 35 mm in diameter in segment IV of the liver. Left hepatic lobectomy was performed based on the diagnosis of mucinous cystic neoplasm of the liver; subsequent histology revealed that the tumor was multi-locular, cystic, and lined with a single layer of columnar epithelium with low-grade atypia and was associated with a typical ovarian-like stroma. There was no evidence (imaging or histological) to support communication of the cyst with the intrahepatic bile duct, despite modest bile deposition being observed in the cystic wall. The definitive diagnosis was mucinous cystic neoplasm with low-grade intrahepatic epithelial neoplasia.
