Type IV-A Choledochal Cyst with Intrahepatic Bile Duct Stricture

Choledochal cysts are rare congenital anomalies of the bile ducts. They consist of cystic dilatations of the extrahepatic biliary tree, intrahepatic radicles, or both. The standard treatment of choledochal cyst is complete excision of cyst and drainage procedure. I report a case of 48-year-old women who was diagnosed with type IV-A. choledochal cyst with intrahepatic bile duct stricture and large stones in extrahepatic choledochal cyst. Sixteen years ago, she received a cholecystectomy and Reux-en Y cystojejunostomy due to choledochal cyst. Because of the intrahepatic bile duct stricture. I performed a left hepatectomy, complete cyst excision and hepaticojejunostomy. I report this case with a review of the literature. (J Korean Surg Soc 2010;78:123-126)
