There are five types of choledochal cysts, which are anomalies that involve intrahepatic or extrahepatic bile ducts, or both. These lesions are found most frequently in patients who are Asian, female, infants but are recognized with increasing frequency in adults. ⋯ Management of choledochal cysts is successful after their complete removal. Partial cyst resection and internal drainage is less satisfactory because of occasional pancreatitis, cholangitis, and cholangiocarcinoma. Resection of the intrahepatic and intrapancreatic portions of the cysts reduces the risk of cancer even though this risk is low after incomplete cyst excision. Biliary continuity after cyst resection is best established by Roux-Y hepaticojejunostomy.
