Abstract    Congenital biliary dilatation (CBD) is the disease that the intrahepatic bile duct or extrahepatic bile duct has congenital development abnormalities alone or in combination. It mostly occurs in women, often found in early childhood. As the applications of medical imaging in clinical, a few had the diagnosis in adulthood. As occurred in the common bile duct with spindle-shaped expansion, CBD was called congenital choledochal cysts previously. The bile retention in the expansive bile duct may be complicated by cholangitis, stones, perforation and malignancy of cyst wall. Congenital choledochal cysts in adulthood without surgical contraindications, once diagnosed, regardless of the severity of symptoms, should be taken a surgical treatment. Currently stand, unless there are special indications, it should not be taken internal drainage or external drainage. Complete removal of the cyst and reconstruction of the extrahepatic bile duct is the standard operation to congenital choledochal cysts.
