1, laparoscopic appendectomy only requires three very small incisions in the abdominal wall (sometimes only two small incisions can be made), hidden in the umbilicus and lower abdomen, with cosmetic effects; 2, no need to tear the abdominal wall muscles, little damage, minor postoperative incision pain; 3, laparoscopy has a magnifying effect, wide field of vision, clear exploration, not easy to misdiagnosis and leakage, especially for patients with doubtful preoperative diagnosis is more suitable. If other lesions (ovarian cysts, intestinal tumors, gastric perforation, etc.) are found intraoperatively, they can be operated directly under the laparoscope without making another incision; 4, laparoscopy can explore all corners of the abdomen and cleanse the pus thoroughly, so there is less chance of abdominal infection, and the incision is not in direct contact with pus, so the incision infection rate is low, especially for more obese patients; 5, laparoscopic surgery has less interference with the intestine, small incision and less chance of infection, so the incidence of postoperative intestinal adhesions The incidence of postoperative intestinal adhesions is low; 6. The postoperative recovery is fast and the hospital stay is short, and the patient can be discharged in 2-3 days.
