title: Studies on subtype "d" biliary atresia.
abstract: Nine cases of specific type (subtype d) biliary atresia were experienced at the Tohoku University Hospital and were classified into three groups on the basis of their clinical and pathological findings. Group 1 cases were defined as cases showing obstruction on the side of the hepatic duct and cystic dilatation, communicating with the gallbladder, in the common bile duct. Group 2 cases were those showing dilatation similar to Group 1, but measuring less than 20 mm, the dilated part being covered with thick connective tissue. Group 3 cases were those showing isolated dilatation in the common hepatic duct or the common bile duct and having no communication with the gallbladder. The postoperative course was good in Group 1 patients, while jaundice was prolonged in Group 2 patients. In Group 3, jaundice disappeared in one patient who died later, while the other patient showed recurrence of slight jaundice.
