Intrahepatic bile duct stones refer to stones located in the branches of the bile duct above the junction of the left and right hepatic ducts. Surgical treatment is currently the main method of treatment. Treatment should be based on the number and distribution of stones within the bile ducts, the location and extent of hepatic and biliary strictures, pathological changes in the liver, the state of liver function, and the patient's overall symptoms. Appropriate surgical approaches should be adopted, including hepatectomy, high position bile ductotomy for stone removal, transhepatic choledochotomy for stone removal, biliary-intestinal internal drainage, liver transplantation, etc.
