Anatomical Variations in the Extra Hepatic Biliary Ductal System

The aim of the study was to study the various anatomical variations occurring in the extra hepatic biliary ductal tract. The study material consisted of 40 adult specimens of liver, gallbladder with duodenum collected enmass from the forensic department. Out of the 40 specimens dissected we came across accessory hepatic ducts all arising from the right lobe of liver. These accessory right hepatic ducts drained into the common hepatic duct at different levels. Knowledge of these accessory ducts confirmed by various intra operative cholangiographic procedures is necessary for avoiding any serious complications during surgery. Hence we conclude that this study will be a useful guideline for the operating Surgeons and Radiologist working in that area.
