The procedure is performed by inserting a special catheter into the peritoneal cavity, injecting about 2-5 liters of carbon dioxide, and then making 2-3 small holes of 0.5-1 cm in the patient’s abdomen after reaching a certain pressure, and then carefully removing the gallbladder under television surveillance connected to the laparoscope. The procedure takes about 0.5 to 1.0 hours and is simple and safe. If the gallbladder is adherent to the surrounding stomach, duodenum, large intestine or large omentum due to chronic inflammation or other causes then a longer operation is required or a traditional cesarean cholecystectomy is performed instead. Post-operative complications: Broadly speaking, post-operative complications can be divided into two categories: medical and surgical. The occurrence of medical complications is not much different from that of general cesarean surgery, however, due to the shortened operative time and the small size of the wound in laparoscopic cholecystectomy, underdilation of the airway is less frequent. In addition, urinary tract infections and phlebitis are also rare. Surgical complications include: (1) bile leakage; (2) bile duct obstruction; (3) residual common bile duct stones; (4) wound infection; (5) shoulder pain; (6) peritoneal effusion; (7) abdominal bleeding. In general, the chance of these complications is low, about 0-3%, and most of them can be cured under the careful care of medical staff. Post-operative precautions: After surgery, there may be transient nausea or vomiting due to anesthesia, which can be treated with medication. If there is no vomiting 8 hours after surgery, you can drink 30-50ml of water first. If the medical staff does not inform you of any special restrictions, you can eat liquid food such as rice soup and porridge on the next day, but avoid whole milk. You can get out of bed and go to the toilet on the same day after surgery, and you can be fully active after 3-6 days without any restriction. Most of the pain in the surgical wound is not severe and oral or intramuscular pain relievers are usually given. The wound usually requires no or only one or two dressing changes. If there is any abnormal bleeding and oozing, please inform the health care provider. A small number of patients may experience mild shoulder pain after surgery, which is caused by irritation of the diaphragm during surgery and will resolve on its own within a short period of time, or a mild fever (temperature between 37-38 degrees Celsius) that will resolve within 1-2 days. The patient can be discharged within 3 days after surgery if there are no special conditions. In older patients or those with neurogenic bladder abnormalities, a catheter is usually left in the bladder and urethra after surgery and can be removed in about 1-3 days. Discharge instructions: The wound is kept clean and clear and no other medications are needed to be rubbed in. If there is a drainage tube and drainage bag in the abdomen, please record the flow and color of drainage every day. The normal color is light yellow and the amount is less than 50 ml per day. Please be careful not to eat excessively greasy food, and try to eat less raw, cold, hard and spicy food within one month after surgery. In most patients, the original gallbladder function can be basically replaced by the liver within 3-6 months.
