Gallstones falling into the bile ducts usually require surgical treatment in order to get cured, otherwise it may cause obstruction of the bile ducts, obstructive jaundice, and in serious cases, it may even cause acute obstructive septic cholangitis and infectious shock, which may jeopardize the patient’s life. For gallstones falling into the bile duct can be performed in two surgical ways, as follows: 1. This surgical method is the most accurate and reliable, that is, through the combination of two scopes, that is, in the laparoscopic cholecystectomy at the same time, laparoscopic choledochotomy to remove the stone, T-tube drainage, so as to obtain a cure. Generally, after the operation, it is necessary to perform cholangioscopy again in 6-8 weeks to confirm that there is no stone residue before removing the T-tube. 2. Mainly in the case of advanced age and inability to tolerate general anesthesia, or acute obstructive septic cholangitis, the risk of anesthesia for the operation is relatively high, you can consider using ESG surgery, ERCP surgery, which means that through the gastroscope, the endoscope will be inserted into the duodenum, the common opening of the pancreatic and bile ducts, and under the endoscopy, the endoscope will be inserted into the duodenum, pancreatic and bile ducts. The endoscope is inserted through the gastroscope into the common opening of the duodenum, pancreatic duct and bile duct, and the stones in the bile duct are removed endoscopically, thus relieving the symptoms of bile duct obstruction and avoiding the triggering of severe acute obstructive septic cholangitis.
