Key Points

• This case describes a rare instance of hepatolithiasis caused by a remnant from previous biliary surgery in a patient with congenital biliary dilatation.
• Case report of a 33-year-old male with Down syndrome and a history of biliary surgery.
• Used imaging techniques to identify stones and remnants in intrahepatic bile ducts.
• Performed left hepatectomy to remove stones and remnants identified during intraoperative cholangioscopy.
