The procedure is performed by inserting a special catheter into the abdominal cavity, injecting about 2-5 liters of carbon dioxide, and then making 3-4 small 0.5-1 cm holes in the patient’s abdomen after reaching a certain pressure, and then removing the gallbladder by careful operation under television surveillance connected to the laparoscope. The operation 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 it will require a longer operation or be converted to a traditional cesarean cholecystectomy. Complications after surgery: Generally speaking, complications after surgery 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, urinary tract infections and phlebitis are rare due to laparoscopic cholecystectomy, which generally does not require the insertion of a catheter, shortened operative time and small wounds. The common surgical complications include: (1) bile leakage; (2) bile duct obstruction; (3) residual common bile duct stones; (4) wound infection; (5) shoulder pain; (6) peritoneal fluid; and (7) abdominal bleeding. The chance of complications is not high, 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 restrictions. 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), which may disappear in 1 to 2 days. The patient can be discharged within 3 days after surgery if there is no special condition. 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. Patients should avoid fried foods (French fries, fried meat, etc.), sweets (cakes, chocolate, cream, etc.), high cholesterol foods (eggs, liver, shrimp, etc.) and green vegetables (lettuce, bean pods, etc.) for at least 15 days after surgery. Afterwards, patients can gradually return to their previous diet, but it is recommended that their daily diet be based on soft foods, reducing calories and fine carbohydrates, and consuming more dietary fiber while reducing fat and cholesterol intake. A low-fat, low-cholesterol diet with sufficient high-quality protein, vitamins and micronutrients is recommended in the early postoperative period and should be maintained for at least 2 weeks. Postoperative fat intake should not exceed 30 g per day, cholesterol intake should not exceed 300 mg per day, and daily energy intake should be 20-25 kcal/kg. Dietary fiber should be soluble fiber from pectin, algae gum and soy gum, and ensure sufficient water intake. It is also important to avoid frying and deep-frying. It is also important to avoid frying and deep-frying. In the first month after surgery, eat as little raw, cold, hard and spicy food as possible. In most patients, the original gallbladder function can be basically replaced by the liver within 3-6 months. Discharge instructions: Keep the wound clean and clear without rubbing other medications. If there is a drainage tube and drainage bag in the abdomen, please record the drainage flow and color every day. The normal color is light yellow and the amount is less than 50ml per day, if the color changes or the drainage volume increases greatly, please go to the hospital at any time.
