Abstract:
Working knowledge of extrahepatic biliary anatomy is of paramount importance to the general surgeon. The embryologic development of the extrahepatic biliary tract is discussed in this article as is the highly variable anatomy of the biliary tract and its associated vasculature. The salient conditions related to the embryology and anatomy of the extrahepatic biliary tract, including biliary atresia, choledochal cysts, gallbladder agenesis, sphincter of Oddi dysfunction, and ducts of Luschka, are addressed.
