Simultaneous double cancers of the common bile duct and the gallbladder; A case report and review of literature in Japan

Abstract

A case of simultaneous double cancers of the common bile duct and the gallbladder was presented. Ultrasonogram and CT scan showed dilatation of the common bile duct and the intrahepatic biliary ducts. PTC showed V-shaped narrowing of the lower common bile duct. Preoperative diagnosis was carcinoma of the common bile duct. Pancreato-duodenectomy was carried out. A polypoid lesion was found at the neck of the gallbladder. Histological findings revealed poorly differentiated adenocarcinoma of the common bile duct, and papillary adenocarcinoma of the gallbladder. Only 16 cases of simultaneous double cancers of the common bile duct and the gallbladder have been reported in Japanese literature.
