With the improvement of living standard, the change of diet structure and the popularity of medical examination, more and more gallbladder stones or gallbladder polyps are found, and a large number of gallbladders are removed every year. The laparoscopic cholecystectomy, which was gradually promoted twenty years ago, has become so mature that even small hospitals can complete it. More and more gallbladders are being cut out. In fact, there are quite a few gallbladders that do not need to be removed. Especially in young people, those with good gallbladder function, single stones and single non-wide-based polyps or cholesterol polyps, it is completely possible to consider the bailout technique to preserve the gallbladder, or for those with a functional gallbladder and no symptoms of stones, there is no need to deal with them at all. Those who need to be treated: those with recurrent acute attacks of cholelithiasis affecting their working life, those with gallbladder atrophy or filled stones, those with multiple stone attacks over jaundice or pancreatitis, or those with cholecystitis gallstone with diabetes over 65 years old; those with gallbladder polyps larger than 1 cm in diameter, and those whose gallbladder polyps cannot exclude malignancy. Due to the increased incidence of intra-biliary stones after gallbladder resection, long-term observation reveals that intra-biliary stones are far more troublesome to deal with than gallbladder stones, and furthermore, in early when the gallbladder is resected, bile discharge into the intestine loses its regularity and the incidence of intestinal cancer increases. Therefore, for young patients, removing the gallbladder at every turn is an irresponsible practice, considering only their own convenience without considering the long-term consequences for the patient.
