Common surgical procedures for choledochal stones include choledochotomy and T-tube drainage, bile-intestinal anastomosis, endoscopic retrograde cholangiopancreatography and lithotripsy, etc. Doctors will determine the most appropriate surgical procedure according to the condition. 1. Choledochotomy with T-tube drainage: Laparoscopic or open surgery can be used. It is suitable for patients with simple choledochal stones, and the upper and lower ends of the bile ducts are clear, without stenosis or other lesions. If accompanied by gallbladder stones and cholecystitis, cholecystectomy should be performed at the same time. To prevent and minimize stone remnants, choledochoscopy, cholangiography or ultrasonography should be done intraoperatively. Intraoperatively, the stone should be removed as much as possible, if the conditions do not allow, the rubber T-tube can also be left in the bile duct, and postoperative cholangioscopy or choledochoscopy should be performed to check and remove the stone. 2. Bile-intestinal anastomosis: the commonly used anastomosis is bile duct jejunum Roux-Y anastomosis. The indications are: the obstruction caused by inflammatory stenosis of the distal common bile duct can not be relieved, dilatation of the common bile duct; bile and pancreatic ducts are abnormal at the confluence part, pancreatic fluid flows into the bile duct directly; the bile duct can not be anastomosed again due to the partial resection of the lesion. 3. Endoscopic retrograde cholangiopancreatography and lithotripsy: It can be applied to most patients with common bile duct stones. The doctor will determine the specific procedure according to the condition, physical condition, and so on. If you suffer from choledochal stone, you should follow the doctor’s instructions to standardize the treatment.
