Anatomical variations of the extrahepatic biliary tree: review of the world literature.
The anatomy facing a surgeon during cholecystectomy involves complex relationships between the hepatic artery, extrahepatic biliary tree, and gallbladder. A sound knowledge of the normal anatomy of the extrahepatic biliary tract is thus essential in the prevention of operative injury to it. Equally important, however, is an understanding of congenital variation of biliary and vascular anatomy, as the literature abounds with reports of specific anatomical variations, and their operative implications. This article reviews the world literature on congenital variation of extrahepatic biliary anatomy.
