The danger of gallbladder stones lies not only in the mechanical stimulation of stones causing right upper abdominal pain and chronic cholecystitis, or mechanical obstruction causing right upper abdominal colic, but more importantly in the complications of gallbladder stones. When gallbladder stones obstruct the gallbladder duct, it may cause: acute cholecystitis, pus accumulation in the gallbladder, gallbladder perforation, biliary peritonitis and other complications. 2. When stones are discharged into the common bile duct through the cystic duct, it may cause secondary common bile duct stones, acute cholangitis, biliary shock, biliary pancreatitis and other complications; 4. When stones press a part of the gallbladder wall adjacent to the duodenum for a long time, it may easily lead to gallbladder duodenal fistula, and larger stones may cause gallbladder cancer by stimulating the gallbladder wall for a long time; some of these complications may endanger the patient’s life in serious cases. It can be seen that the danger of gallbladder stone complications is far more than ordinary people can imagine. Nowadays, some hospitals, under the signboard of “new technology” and “innovative minimally invasive”, are expanding the implementation of gallbladder stone “stone extraction and gallbladder preservation” (removing stones to preserve the gallbladder), which brings new pain to patients. This has caused new pain to patients. In fact, lithotripsy is not a new technology or a new concept, but has been eliminated by the surgical community because of the poor postoperative results. There are strict surgical indications for lithotripsy, which requires normal gallbladder contraction (fatty meal test of the gallbladder, requiring gallbladder contraction area of more than 30%), and very few patients are suitable for lithotripsy. Even if the surgical indications are strictly controlled, the biggest “weakness” of lithotripsy is the high recurrence rate of stones after surgery, and patients with recurrence need to undergo cholecystectomy again, in addition to leaving behind gallbladder lesions with no obvious symptom relief and high cancer rate.
