ERCP lithotripsy is endoscopic lithotripsy, no difference. The common clinical methods of microscopic stone extraction include ERCP stone extraction and laparoscopic choledochotomy, and the main difference is that the surgical methods are different, the advantages are different, and the disadvantages are not the same. The following is a detailed description of the differences between ERCP and laparoscopic choledochotomy methods, advantages and disadvantages: 1. ERCP lithotripsy, endoscopic choledocholithotripsy (1) Surgical method: insert the duodenoscope into the descending part of the duodenum through the mouth, find the duodenal papilla, and through a small incision in the duodenal papilla, carry out the operation of lithotripsy, stone extraction, and cleaning of extrahepatic bile duct stones. (2) Advantages: no incision, less trauma, shorter operation time, fewer complications than surgical operation, much shorter hospitalization time, low treatment risk, etc. (3) Disadvantages: ERCP surgery for bile duct stone extraction can damage the sphincter of Oddi. 2.Laparoscopic bile duct stone extraction (1) Surgical method: 3-4 small holes are made in the abdominal wall, and the gallbladder is completely cut off under laparoscopic guidance by inserting appropriate instruments, and then the bile ducts are incised and the bile duct stones are removed from the small holes in the abdominal wall. (2) Advantages: preservation of the structural integrity of the sphincter of Oddi’s, small incision, fast postoperative recovery, less likely to recur. (3) Disadvantages: as a laparotomy, the microscopic field of view is small, the operation is inconvenient, if the operation meets acute complications, there is a risk of transferring to open surgery. ERCP lithotripsy is endoscopic lithotripsy, and the difference between ERCP lithotripsy and abdominal choledochotomy is as above, they have their own advantages and disadvantages, the patient should go to a regular hospital, by the specialist to provide comprehensive assessment of the choice of surgical methods of advice.
