Bile Duct Cysts in Adults

Abstract

In patients with BDC, particular attention must be given to the associated intrahepatic bile duct dilatations. We propose a modification of Todani's classification to distinguish cystic, segmental, and fusiform dilatations of the intrahepatic biliary tree in type IV cysts. In patients with segmental left intrahepatic cystic dilatations, combined left liver lobectomy and extrahepatic cyst excision is suggested to decrease late postsurgical biliary complications.
