Single gigantic calculus of common bile duct and multiple hepatolithiasis

Choledocholithiasis is a very common surgical disease worldwide. Reports of a single calculus of the common bile duct >10 cm are very rare. The authors present a case of a single gigantic calculus in the common bile duct with multiple stones distributing in the left intrahepatic ducts. The patient was treated with left hemihepatectomy combined with Roux-en-Y hepaticojejunostomy, and the postoperative course was uneventful. Left hemihepatectomy combined with Roux-en-Y hepaticojejunostomy was the optimal treatment for this patient, with a satisfactory outcome.
