Minimally invasive surgery for gallstones mainly refers to laparoscopic surgery. More and more people are willing to undergo this surgery, which currently has the advantages of quick recovery and minimal trauma. The operation time usually ranges from 1-5 hours. The procedure is performed under general anesthesia and requires preoperative preparations such as infusion of carbon dioxide gas into the abdominal cavity, which is an integral part of the laparoscopic procedure. In fact, if the operation goes smoothly, the time taken for the operation is not long. 1. For stones present in the gallbladder alone, the operation is completed after complete removal of the gallbladder and a few stitches after closing a very small wound. This can be done in less than an hour by many skilled surgeons. 2. In some people, the gallstone disease is more complicated and the bile duct is filled with many stones. Therefore, during the operation, not only the diseased gallbladder has to be removed completely, but also the bile duct has to be cut open, the stones have to be removed, and finally a drainage tube has to be placed in the bile duct and fixed properly. This makes the laparoscopic operation quite difficult and takes longer. 3, unlike open surgery, which requires direct vision, laparoscopic surgery requires observation of the operating site through a TV screen, with a clearer view, while the laparoscope can magnify the operating field and rotate the laparoscope position at will, with a clearer view. During surgery, there are few unexpected biliary tract or other tissue injuries or bleeding problems. However, laparoscopic surgery is performed with instruments. For patients with recurrent cholecystitis or a history of previous abdominal surgery, there are upper abdominal adhesions, and it takes some time to separate the adhesions during the operation, and the operation time for these patients should be increased appropriately. Laparoscopy is a mature surgery and is favored by the majority of patients, but the surgery needs to master the indications to avoid some surgical side injuries.
