There are several approaches to surgery for bile duct stones.
Common surgical treatments for bile duct stones include choledochoscopy stone removal, laparoscopic surgery, and traditional open surgery.
1. Choledochoscopy Stone Removal
Choledochoscopy stone removal, also known as endoscopic retrograde cholangiopancreatography (ERCP) stone extraction, involves inserting a duodenoscope through the patient's mouth into the esophagus, stomach, and distal duodenum to locate the lesion. After cannulation and contrast injection, stones are removed from above downward. Its limitations include difficulty in completely clearing stones, and it is not suitable for large stones or stones located close to the liver.
2. Laparoscopic Surgery
When bile duct stones are accompanied by gallstones, laparoscopic cholecystectomy combined with common bile duct exploration and stone removal is performed. This approach effectively treats both gallbladder and bile duct stones.
3. Traditional Open Surgery
Open surgery is recommended when there are numerous stones in the common bile duct, concurrent gallstones, or intrahepatic bile duct stones, as it offers better therapeutic outcomes.
Surgical treatment of bile duct stones should follow principles including complete stone clearance, removal of the underlying pathology, routine drainage, and prevention of recurrence. Patients should seek timely medical evaluation and, under physician guidance, select the most appropriate surgical method.
