Minimally invasive surgery for gallstones usually requires the operation of surgical instruments under 2-3 microscopic holes in the abdomen, which takes about 0.5-1 hour, but the specific difference depends on the situation of each individual.1. Heavy inflammation of gallstones: In this case, it is relatively more difficult to take minimally invasive surgery, and in the case of gallstones combined with acute inflammation, or some chronic inflammation is more intense, the surgical operation is more difficult at this time It is more difficult to separate. Many acute attacks, such as congestion, edema, and bleeding will also increase, and the process of separation should be done carefully so as to avoid heavy bleeding, or unexpected complications, other organ damage, and other factors, such as bile duct injury. In this case, the operation time will be extended accordingly, even 4-5 hours are possible. In addition, it may be transferred to open surgery, which will prolong more time accordingly; 2, abdominal adhesions: the operation is more difficult, although it is not some emergency surgery, but in some cases, the gallbladder has been operated in other parts, and there are certain adhesions in the abdominal cavity, but still consider to give minimally invasive treatment, minimally invasive to first separate the original adhesions, or because of some abnormal anatomical structure, abnormal individual factors during the operation The minimally invasive surgery does not take place as soon as the patient enters the operating room, but also requires preoperative waiting, preoperative anesthesia, postoperative awakening, and postoperative observation time, which can sometimes be more time-consuming. Although some surgical operations are only half an hour, the waiting and observation time before and after anesthesia may be longer, so it generally takes at least 1-2 hours after entering the operating room before being able to leave the operating room, but this does not mean that all of them belong to the surgical time. Overall, the exact time of minimally invasive gallstone surgery depends on each individual’s situation. If there is no obvious inflammation, no special or obvious underlying disease at the time of examination, or a good physical condition, the surgery can be completed in about 0.5-1 hour.
