Study of Abnormal Anatomical Variations in Extrahepatic Biliary Apparatus and Its Related Vessels in Cadavers

Background: In the current era, the laparoscopic procedure such as laparoscopic cholecystectomy, laparoscopic hepatobiliary surgery and other open procedures such as open cholecystectomy, biliary stricture surgery, are performed regularly throughout the world and extrahepatic biliary tract is one of the most common sites of the surgical procedures. The incidence of biliary tract injury by laparoscopic cholecystectomy has been found to be higher than open cholecystectomy. Apart from various other causes of biliary injuries aberrant anatomical course of extrahepatic biliary system is a well established fact of iatrogenic ductal injury. Thus, an adequate recognition and awareness of anatomical abnormalities of extra hepatic biliary tree with its vessel, can decrease the morbidity and mortality related to the surgery.
