Choledochal cysts are rare congenital abnormalities that result in cystic dilations of the bile ducts. They harbour the potential for complications including cholangitis and malignant degeneration to cholangiocarcinoma. They are treated with surgical excision.
It can be performed with laparoscopic excision of a large choledochal cyst involving the entire common hepatic and common bile duct.
The cyst is successfully excised in its entirety through a laparoscopic approach. Biliary tract continuity is re-established through a Roux-en-Y hepaticojejunostomy, also performed laparoscopically.
Laparoscopic surgical excision of choledochal cysts with biliary reconstruction is safe and feasible.
