Surgical methods I: bile duct exploration. Surgical methods II: bile duct exploration and Roux-en-Y cholangiojejunostomy. Surgical methods III: bile duct exploration and partial hepatectomy. Surgical methods IV: exploratory laparotomy, bile duct exploration, partial hepatectomy, and Roux-en-Y cholangiojejunostomy. Surgical methods A: bile duct exploration, extrahepatic bile duct resection, partial hepatectomy, hilar ductoplasty, and Roux-en-Y hepaticojejunostomy. Surgical methods B: bile duct exploration, extrahepatic bile duct resection, hilar ductoplasty, and Roux-en-Y hepaticojejunostomy. MRCP, magnetic resonance cholangiopancreatography; CT, computed tomography. ^aIn 72 patients with diffuse stones, intrahepatic stones were distributed in both the left and right hepatic ducts.
