Gallstone surgery encompasses a variety of situations, and whether the surgery is big or not depends on the specific analysis of the situation. If it is a simple gallstone surgery, there are mainly open cholecystectomy, laparoscopic cholecystectomy and laparoscopic biliary stone retrieval surgery, which itself belongs to 2-3 level surgery and is generally not big; however, if gallstones are combined with severe acute infection, it is an emergency surgery and is relatively big. If it is just a simple gallstone surgery usually the operation is not difficult, as long as the adhesions between the gallbladder and liver are separated, then the gallbladder duct gallbladder artery is ligated and cut, or the bottom of the gallbladder is opened and the stones are removed from the gallbladder, and then the extraction port is sutured, the surgery is completed. If minimally invasive treatment is used, the surgery is less invasive and the patient recovers faster after surgery. Thus, the surgery for gallstones in this case is not considered major. If the gallstones are combined with acute infection or bile leakage due to gallbladder gangrene perforation, the gallbladder wall will be congested and edematous, which will easily lead to bleeding and unclear separation, resulting in serious complications and related organ and bile duct damage. In addition, if the patient undergoing gallstone surgery is too old, has poor physical condition, poor cardiopulmonary function or has had previous abdominal surgery, or has obvious abdominal adhesions, the difficulty of surgery is also relatively higher. In addition, after gallstone surgery, patients need to abstain from water as prescribed by the doctor, and after exhaustion, they can eat light, easy-to-digest liquid food, such as white porridge, vegetable porridge, etc. Avoid cold and stimulating, spicy and greasy food, such as fried chicken, chili, etc. Also pay attention to postoperative wound care, avoid infection, ensure sufficient sleep, etc.
