摘要
Choledochal cysts are benign cystic dilatations of the extra-and intrahepatic bile ducts[1,2].If untreated,their sequelae include recurrent cholangitis,secondary biliary cirrhosis,acute pancreatitis,and cholangiocarcinoma[3,4].Todani et al.[5]classified choledochal cysts into 5 subtypes,of which type V is Caroli’s disease.The disease is either localized,where unilobar biliary dilatation,commonly in the left,is present,or diffuse,where the entire liver is involved.
