A 60-year-old woman was seen at the hospital because of vomiting. Computed tomography and an abdominal ultrasonography revealed dilatation of the bilateral intrahepatic bile duct and intrahepatic stones. Percutaneous transhepatic biliary drainage (PTBD) was performed. Cholangiography suggested that this patient had undergone and excision of the dilated extrahepatic bile duct with hepaticojejunos-tomy (Roux-en-Y) for congenital bile duct dilatation. Anastomotic stenosis and defects in bilateral intrahepatic bile ducts were revealed. Bilateral intrahepatic bile ducts stones were observed by a percutaneous transhepatic cholangioscope (PTCS). Electrohydraulic lithotripsy (EHL) was made as much as possible. Dilation of anastomosis and re-hepaticojujunostomy were performed. EHL and balloon dilation by PTCS for bile duct stenosis were made frequently after the operation, and a complete removal of stones was comfirmed.
