Abstract
We have studied anomalous arrangement of the pancreaticobiliary ductal system (AAPBDS) which is a high risk group of carcinoma of the biliary tract. Fourteen cases of AAPBDS were diagnosed by FRCP, which we performed on 1432 cases during the past nine years. Six of the 14 cases were complicated by gallbladder carcinoma, and two of them were resected. During the same period we treated 30 cases of gallbladder carcinoma. However, no cases of bile duct carcinoma had complications.
Four cases of cholelithiasis were combined with AAPBDS, and one of these four was complicated by gallbladder carcinoma. There were 14 cases (58.3%) of cholelithiasis among patients with gallbladder carcinoma without AAPBDS. Bile amylase collected during the operations was elevated in eight of nine cases.
Although AAPBDS is relatively rare, carcinoma of the biliary tract is often complicated. Therefore, it is necessary to choose surgical resection in the treatment of patients with AAPBDS.
