Laparoscopic cholecystectomy is currently the treatment of choice for gallbladder stones and gallbladder polyps. Compared with traditional open surgery, it has the advantages of small incision, low injury, mild postoperative pain and light postoperative adhesions, which enable patients to leave bed early and resume work, and save hospitalization costs. The procedure is performed by making 3-4 small incisions of 5-10mm in diameter in the abdomen under general anesthesia, injecting CO2 into the abdominal cavity, inserting a laparoscope and operating instruments, and then performing cholecystectomy under the supervision of a TV screen. Please cooperate with the surgeon one day before the operation to complete the preoperative preparation, especially to pay attention to the cleanliness of the umbilicus and to abstain from food and water in the morning of the operation. The doctor will inform you of the details of the operation and sign the interview one day before the operation. After the operation, we will take care of you according to the general anesthesia care routine. After the recovery of anesthesia and waking up, you can gradually sit up and change to semi-recumbent position (usually 4-6 hours), while you can turn over. Most patients can resume anal venting on the first postoperative day and eat an appropriate liquid diet, and then gradually transition to a semi-liquid diet. Common postoperative discomforts include: 1. Incisional pain is generally mild, and most patients do not need pain medication. Sometimes there may be mild shoulder and back pain in the short-term postoperative period, which is related to the stimulation of the phrenic nerve by CO2 during pneumoperitoneum. 2, nausea and vomiting are usually caused by the reaction of anesthetic agents, and the symptoms can be gradually relieved as the anesthetic drugs are metabolized. 3, Laryngeal discomfort and increased sputum may be due to tracheal insertion stimulating the tracheal mucosa to produce secretions, which must be coughed up to prevent pulmonary complications. If the recovery is smooth, most patients can be discharged on the next day or the next day after surgery. The specific time and process of discharge procedures can be discussed with the bedside doctors and nurses. Before discharge, we will change your wound dressing. After discharge, please pay attention to the following points: 1. Surgical incision: We routinely apply absorbable sutures to close the wound, and there is no need to remove the sutures and change the medication again after discharge, but please pay attention to keep the incision clean and dry, and avoid a sharp increase in negative pressure (such as violent cough or constipation) in the near future to avoid pain and cracking of the incision. If there is redness, swelling and exudation of the incision, please contact the doctor in time for follow-up. 2.Post-operative diet: The recovery of digestive tract function varies from person to person, some patients will have indigestion, anorexia, diarrhea and other symptoms after surgery, most of which can be gradually reduced. In terms of dietary regularity: regular and quantitative, small and frequent meals, chew and swallow slowly, not too full, avoid overeating. In terms of diet structure: low fat, low cholesterol, high vitamin, high fiber, high quality protein; eat more vegetables and fruits, light and easy to digest diet; avoid spicy, wine and other stimulating food. 3.Post-operative activities: generally, light physical activities can be carried out one week after surgery. 4.Post-operative review: If there is no special discomfort, the abdominal ultrasound can be reviewed in the outpatient clinic one month after surgery. If symptoms such as epigastric pain, bloating after eating, fever, yellow sclera of skin, etc. occur repeatedly or continuously after surgery, please contact the doctor and seek medical consultation in time.
