The biggest difference between laparoscopic surgery and open surgery is that carbon dioxide needs to be injected during the operation to make pneumoperitoneum easy to operate, so carbon dioxide gas is easy to remain in the abdominal cavity after the operation. Therefore, the intake of vegetables and high-fiber fruits should be increased in the diet after laparoscopic surgery, and gas-producing foods such as sweet potatoes, beans and onions should be added. It should be avoided to reduce the discomfort caused by postoperative abdominal distension. As for large laparoscopic surgery, such as hysterectomy, intestinal adhesion reduction, radical operation of cervical cancer, etc., it is more appropriate to eat after 24 hours because of the long anesthesia time and long operation time, more gas is absorbed by the gastrointestinal tract, and abdominal distension is more likely to occur. For patients who are prone to nausea and vomiting after surgery and patients with specific physique, it is not necessary to force themselves to eat, and they can eat after anesthesia is completely relieved.
