The sequelae of gallstone surgery may include ductal stenosis, bile reflux, and post-cholecystectomy syndrome. 1. Bile duct stenosis: when gallstones are surgically treated, the bile ducts may be explored, which may be damaged in the process and may cause bile duct stenosis in the process of recovery. 2. Bile reflux: it often occurs after extrahepatic bile duct stone surgery, the duodenal papilla may be damaged during the surgery, and bile reflux is likely to occur after the surgery. 3. Post-cholecystectomy syndrome: it usually occurs within six months after the operation, and it is often characterized by intermittent or persistent pain in the right upper abdominal area and quaternary rib area. To summarize, if discomfort occurs after gallstone surgery, you should consult a doctor in time.
