We reviewed congenital choledochal cyst with intrahepatic
Involvement In 38 patients aged 52 days to 29 years. Dilatations were classified
into the following three forms, based on the shape of the extrahepatic and
intrahepatic bile duct: cystic-cystic, cystic-cylindrical, and cylindrical-cylindrical.
Stenosis of the hepatic duct near the helium probably does not cause dilatation
of the intrahepatic duct. The anomalous arrangement of the pancreatobiliary
union seems to determine only the form of extrahepatic dilatation, and cystic
dilatation of the intrahepatic duct may be caused by some other factors.
Total excision of the extrahepatic bile duct with the creation of a wide
anastomotic stoma apparently is the treatment of choice. Hepatectomy would
be recommended for some patients with the cystic-cystic form.
