The endoscopic minimally invasive biliary stone extraction method is another new contribution of cholangioscopy technology to gallbladder stone treatment, which is a new theory, new concept and new development in gallbladder stone treatment. Since the choledochoscope can enter the gallbladder for direct visual inspection, it can really ensure whether the stones are removed from the gallbladder or not, which is very accurate. In the past, he found that the gallbladder stones were very easy to recur after the operation, and the recurrence rate was 80%-90%; he did not consider whether the gallbladder stones were really removed, and never considered whether the gallbladder function was important, so he rashly made the decision that the gallbladder must be removed for the treatment of gallbladder stones, regardless of whether the gallbladder function was important or not. The importance of gallbladder function is ignored. Preserving the gallbladder and removing it have very important effects on the human body. After cholecystectomy, the physiological balance of the body is greatly affected, reflecting the importance of the gallbladder function, which should not be removed at will but should be protected by all means.
