title: Operative treatment of congenital stenoses of the intrahepatic bile ducts in patients with choledochal cysts.
abstract: BACKGROUND
  Postoperative complications including intrahepatic calculi may develop after the complete excision of a choledochal cyst. Since congenital stenoses of the intrahepatic bile ducts are more likely the cause of intrahepatic calculi, operative procedures for intrahepatic stenoses are reported.
  
  
  METHODS
  There were 16 patients with choledochal cysts who underwent surgery for stenoses of intrahepatic bile ducts. The stenoses were excised at the opening of the common hepatic duct.
  
  
  RESULTS
  In the 16 patients, 25 of the 26 stenoses that involved an intraluminal membrane or septum could be excised from the divided end of the common hepatic duct at the hepatic hilum. In 1 patient, the stenosis could not be accessed from the hepatic hilum, and a left hepatic lobectomy was required. In postoperative follow-up, all 16 patients were in good health.
  
  
  CONCLUSIONS
  Stenoses of the intrahepatic bile ducts should be treated from the divided end of the common hepatic duct at the initial operation for choledochal cysts. The need for a second operation or hepatic lobectomy may thus be avoided.
