Case ReportsComputed tomography virtual endoscopy with angiographic imaging for the treatment of type IV-A choledochal cyst.
Type IV-A choledochal cysts (CCs) are a congenital biliary anomaly which involve dilatation of the extrahepatic and intrahepatic bile ducts. We present the case of a 30-year-old woman with type IV-A CC, on whom three-dimensional computed tomography (3D CT) and virtual endoscopy were performed. 3D CT revealed partial dilatation in the posterior branch of the intrahepatic bile duct and a relative stricture between it and the extrahepatic bile duct. ⋯ Based on these image findings, complete cyst resection, bile duct plasty for the stricture, and hepaticojejunostomy were safely performed. To the best of our knowledge, there are no reports of imaging by virtual endoscopy of the biliary tract which show the surrounding blood vessels running along the bile duct.

Multicenter Study Comparative StudyWeekend and nighttime effect on the prognosis of peptic ulcer bleeding.
To evaluate whether weekend or nighttime admission affects prognosis of peptic ulcer bleeding despite early endoscopy. ⋯ Early endoscopy for peptic ulcer bleeding can prevent the weekend effect, and nighttime admission was identified as a novel risk factor for rebleeding, namely the nighttime effect.

Factors predicting survival in patients with proximal gastric carcinoma involving the esophagus.
To investigate the clinicopathologic features which predict surgical overall survival in patients with proximal gastric carcinoma involving the esophagus (PGCE). ⋯ Patients with PGCE showed worse overall survival in elderly, high nodal burden and advanced pathologic stage. This cancer may be more accurately staged as gastric, than esophageal, cancer.

ReviewMulticausality in fatty liver disease: is there a rationale to distinguish between alcoholic and non-alcoholic origin?
Apart from alcohol, there are other factors that may induce complications, which resemble alcohol-related liver disorders. In particular, obesity has been brought into focus as a risk factor for fatty liver disease. The term "non-alcoholic" fatty liver disease is commonly used to distinguish between obesity-related and alcohol-related hepatic steatosis. ⋯ Risk factor reduction is the main principle of prevention and treatment of both disease forms. In conclusion, alcoholic and "non-alcoholic" fatty liver diseases are one and the same disease caused by different risk factors. A shift from artificial categories to a more general approach to fatty liver disease as a multicausal disorder may optimize preventive strategies and help clinicians more effectively treat patients at the individual level.

Case ReportsDifficulty in differentiating two cases of sigmoid stenosis by diverticulitis from cancer.
The incidence of colonic diverticulosis with or without diverticulitis has increased in the Japanese population due to the modernization of food and aging. The rate of diverticulitis in colon diverticulosis ranges from 8.1% to 9.6%. However, few cases of stenosis due to diverticulitis have been reported. ⋯ Contrast-enhanced abdominal CT revealed multiple diverticula, wall thickening, and swelling of the lymph nodes around the peritoneal aorta and the inferior mesenteric artery. A partial sigmoidectomy was performed. Pathological examination of the resected specimen revealed no changes in the mucosal epithelial surface, but a marked infiltration of inflammatory cells was observed.
