An Unusual Variation of Extra Hepatic Biliary Ductal System: Hepaticocystic Duct (original) (raw)

Abstract

Aim: The aim of this study was to focus on the variations occurring in the formation of extra hepatic biliary tract. These variations can occur from the gallbladder, cystic duct, hepatic ducts, common bile duct. Most of these variations are due to aberrations in the normal embryological development. Materials and Methods: The study was carried out in 25 foetal specimens of 7 to 9 months gestational age collected from the obstetrics and gynaecology department, Madras medical college, Chennai. Gallbladder was identified and dissection was carried out from the neck of gallbladder. Cystic duct, right hepatic duct, left hepatic duct, common hepatic duct and common bile duct were traced out. The relation of hepatic artery to the duct system was also noted. Result: This study reports an unusual variation in a foetal specimen out of 25 foetal specimens studied by dissection. In one of the specimen the common bile duct was absent. A small common hepatic duct from the liver entered directly i...
