Surgical treatment of congenital dilatation of bile duct (choledochal cyst) with technical considerations.

Since the concept of an anomalous junction of the pancreaticobiliary ductal system was introduced, there has been rapid progress in the study of the pathophysiology and the surgical treatment of choledochal cyst, or congenital dilatation of the bile duct. Because of its various disadvantages, cystoenterostomy as a routine procedure for treatment of this condition has been superseded by hepaticoenterostomy after removal of the devastated bile ducts with blocking of communication with the pancreatic ducts. This article describes the technical details of the surgical correction of choledochal cyst.
