Variations of the Extrahepatic Biliary Tract: Cadaveric Study

Abstract

The extra-hepatic biliary tract includes: right and left hepatic ducts, common hepatic duct, gallbladder, cystic duct and common bile duct. The variation in this system is seen in less than 50% of the cases. This study was carried out to describe the anatomical variations of the extra-hepatic biliary tract as these variations are important during surgical procedures such as laparoscopic cholecystectomy thereby decreasing the post-operative complications.
