The gallbladder, common hepatic duct and common bile duct together form the biliary system of the body to perform the functions of transporting, storing, concentrating and excreting bile. If the structure of the biliary system or the composition of the bile changes, solid crystals may form anywhere in the biliary system, which are known as gallstones. If the gallstones are very small, the patient usually does not feel it obviously; if the gallstones are larger, the patient will have fever, chills, nausea, vomiting, abdominal pain and other symptoms, and it can also cause jaundice, cholangitis and pancreatitis and even gallbladder cancer, therefore, the gallstones should be treated as early as possible. At present, the main surgical methods for the treatment of gallbladder stones are laparoscopic cholecystectomy and laparoscopic combined with choledochoscopic cholecystectomy. Among them, there has been a debate among clinicians about the treatment of cholecystectomy, because after cholecystectomy, the gallbladder still has abnormal cholesterol metabolism, resulting in a high recurrence rate of stones after surgery. Laparoscopic cholecystectomy has become the gold standard for the surgical treatment of gallbladder stones at home and abroad because of its precise efficacy and minimal trauma, and is now the preferred treatment for gallbladder stones in all major hospitals. There is little significance in preserving the diseased gallbladder The impact of gallbladder removal on human health is minimal. Because bile is secreted by the liver and the gallbladder only plays a storage and concentration function, there is no significant change in the original bile secretion after removal of the gallbladder. There is a view that gallbladder resection is prone to disadvantages such as biliary dysfunction, postoperative intestinal obstruction, colon cancer, postoperative diarrhea, reflux gastritis and reflux esophagitis. However, it is found in the clinic that except for less than 5% of patients who are prone to increased stool frequency after eating a high-fat diet after surgery, the rest of the manifestations are very rare, and generally after 1 year, most patients’ diarrhea can disappear through self-regulation. In fact, after having gallbladder stones, a large proportion of patients have no concentrated gallbladder function. Stones are prone to recurrence after gallbladder preservation If the gallbladder has been removed, it is impossible to have gallbladder stones again, and the recurrence rate of stones 2 years after gallbladder preservation is reported to be high both at home and abroad, and most patients will be forced to undergo a 2nd operation, which will be more difficult and dangerous because of the adhesions that occurred after the first operation. This shows that there is little need for patients with gallbladder stones to insist on choosing gallbladder preservation surgery. If the patient insists on preserving the gallbladder, generally speaking, the following 4 conditions should be met, otherwise the recurrence rate of stones is high: 1. mild symptoms or no obvious symptoms; 2. ultrasound examination indicates no significant thickening of the gallbladder wall and normal gallbladder contraction function; 3. good gallbladder visualization by oral method cholecystography and normal gallbladder contraction function; 4. the stones are solitary.
