Laparoscopic appendectomy is a new surgical approach that emerged with the development of laparoscopic techniques. 1983 Semm reported the first case of laparoscopic removal of a non-acutely inflamed appendix, 4 years before laparoscopic cholecystectomy. In contrast, laparoscopic appendectomy for acute appendicitis was first reported by Semm in 1987. Numerous prospective, randomized controlled studies have confirmed the superiority of laparoscopic appendectomy over conventional open appendectomy for appendicitis in terms of shorter hospital stay, fewer postoperative complications, and faster recovery. In cases where the diagnosis cannot be confirmed before surgery, intraoperative exploration has a wider field of view than open surgery, and it is more superior for finding and removing retroperitoneal and subhepatic ectopic appendixes, which is more suitable for obese patients. It is a safe and reliable minimally invasive surgical method. If the diagnosis of acute appendicitis is established, laparoscopic appendectomy can be performed on a trial basis, and if intraoperative difficulties in laparoscopic appendectomy are found, the procedure can be converted to open surgery. However, in the following cases, open surgery must be performed in a timely manner: 1. necrosis and perforation of the appendix root, the appendix stump cannot be reliably treated; 2. a mass is palpated in the right lower abdomen, the appendix is seriously adhered to the adjacent intestinal canal or other organs, and when the formation of appendiceal abscess is considered, the anatomical relationship is unclear, so surgery is not performed for the time being, active anti-infection treatment and close observation of the changes in the condition; 3. the appendix is ectopic in the peritoneum or in the wall of the cecum, and dissection is difficult; 4. 4. malignant tumor of the appendix; 5. history of lower abdominal surgery and estimated difficulties in establishing pneumoperitoneum.
