Abstract
A 50-year-old man was admitted to the hospital because of epigastric pain and hyperamylasemia. Abdominal CT and ultrasonography revealed few polyps in the gallbladder. ERCP film showed the common channel of 23mm in length and common bile duct of 8mm in width. A diagnosis of anomalous arrangement of the pancreaticobiliary duct without dilation of the common bile duct was made. The values of amylase of bile juce were 9, 700 IU/l in the gallbladder and 177, 700 IU/l in the common bile duct. So cholecystectomy with resection of the extrahepatic common bile duct and hepatico-jejunostomy were performed. By histopathologic study a papillaryadenocarcinoma (m, ly0, v0) was found in a part of the gallbladder well. In a review of the Japanese literaure, only 11 cases of early cancer of the gallbladder assosiated with anomalous arrangement of the pancreaticobiliary duct without diliation of the common-bile duct could be seen.
