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 of treating the symptoms but not the root cause, and the postoperative complications of biliary stone extraction are very high and 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.
