Intestinal obstruction in the terminal ileum caused by an anomalous congenital vascular band between the mesoappendix and the mesentery: report of a case.

We report a case of intestinal obstruction caused by a congenital abnormal vascular band in a 17-year-old boy. The patient was admitted with acute colicky abdominal pain, and an emergency laparotomy revealed that the ileum was strangulated by a fibrous band with vessels about 2 mm in diameter and 7 cm in length, extending from the antemesenterium of the terminal ileum to the mesoappendix. The affected intestine was resected with the band and the appendix.

Bile duct cancer developing 21 years after choledochoduodenostomy.

Background: Cholangiocarcinoma in patients with choledochoenterostomy has been a rare condition with few cases reported in the literature written in English, and there have been few pathological descriptions of this disease. However, it has recently been documented as a late complication of choledochoenteric anastomosis, and has become a serious issue today since choledochoenterostomy and sphincteroplasty for benign biliary lesions were frequently resorted to in the 1970s and 1980s. The authors here present a case of a 67-year-old woman who developed a cholangiocarcinoma 21 years after choledochoduodenostomy.

Pseudoaneurysm of the cystic artery with hemobilia treated by arterial embolization and elective cholecystectomy.

Pseudoaneurysm of the cystic artery is a rare cause of hemobilia, with only 11 cases having been reported in the English literature. We report this unusual condition in a 62-year-old Japanese man whose chief complaint was repeated upper abdominal pain. A liver function test showed obstructive jaundice, and endoscopy revealed a small amount of blood coming from the papilla of Vater.
