Whether gallstone preservation can preserve the gallbladder and remove the stones is more controversial. However, the mainstream academic view is against biliary stone extraction, which is a method to treat the symptoms but not the root cause, and the postoperative morbidity of biliary stone extraction is very high, while it is easy to recur. Recurrence followed by cholecystectomy adds a great deal of difficulty to the operation. In many cases, gallbladder stones such as >3cm, gallbladder atrophy, gallbladder wall calcification, recurrent cholecystitis, etc., there is no longer much point in preserving the gallbladder. Moreover, if the gallbladder is preserved, the gallbladder stones will easily irritate the gallbladder wall and induce cancer of the gallbladder. Therefore, the current mainstream doctrine generally considers gallbladder stone preservation undesirable.
