成人先天性胆道拡張症の6例

We report six patients with adult congenital biliary dilatation treated by surgery. Of the six cases, five were female and the patients' age at diagnosis ranged from 19 to 51 years old. By Todani's classification for bile duct dilatation, three were categorized as Ⅰa, one as Ⅰb, and two as Ⅳa. All six cases had anomalous arrangement of the pancreatobiliary duct. Resection of the cystic portion and hepaticojejunostomy (Roux-Y) were performed in all. After surgery, one patient classified as Ⅰa and one as Ⅳa had complications of cholangitis and intrahepatic stones. We removed the stones by the percutaneous transhepatic route with dilatation of the stenotic anastomosis, but cholangitis recurred in the Ⅳa patient. Although surgical resection of the cystic portion and reconstruction of biliary tract is considered to be a standard treatment for adult congenital biliary dilatation, this Ⅳa case had complications after surgical treatment. Thus short-term follow-up is necessary to prevent or diagnose stenotic anastomosis following the operation.
