During 13 years between 1972 through 1985, 129 patients with biliary atresia were treated at the Tohoku University Hospital. Nine of them showed special form (subtype "d") of obstruction of extrahepatic bile duct. They can be divided into 3 groups. Group 1: Type III biliary atresia with large cystic dilatation of choledochus, Group 2: Type II and III biliary atresia with small cystic dilatation of choledochus which was surrounded by thick fibrous tissue, Group 3: Type III biliary atresia with solitary small cyst at hepatic duct or choledochus. Postoperative course was uneventful incases of group 1. All patients in group 2 showed prolonged jaundice, and the patients in group 3 showed high portal pressure at the time of operation. Mutual relationship among subtypes was suggested by their clinical and histological findings.
