Laparoscopic management of type VI choledochal cyst with common bile duct stone: report of a case and review of literature

BMJ Case Rep. 2021 Oct 13;14(10):e244393. doi: 10.1136/bcr-2021-244393.


A young adult male presented with biliary colic and intermittent jaundice for 1 year. Abdomen findings were unremarkable. Routine investigations revealed a raised total bilirubin. On abdominal ultrasonography, common bile duct (CBD) dilatation with multiple stones was noted. On further imaging with magnetic resonance cholangiopancreatography, type I choledochal cyst (CDC) was suspected. A laparoscopic approach was planned. Intraoperatively, dilatation of cystic duct was noted which constitute type VI CDC. Partial malrotation of the gut and accessory right hepatic artery were also noted as incidental finding. Laparoscopic cholecystectomy with CBD exploration and removal of stones, biliary stent placement, cystic duct cyst excision and primary repair of CBD was done. Postoperatively, the patient improved symptomatically with a fall in bilirubin to normal range. We are describing the laparoscopic management of a rare case of type IV CDC which was diagnosed intraoperatively.
