Traditional appendectomy has been performed for more than 100 years and is a classic and mature procedure for the treatment of acute appendicitis. However, laparoscopic appendectomy techniques are also becoming increasingly sophisticated and have become a safe and reliable treatment method. It is particularly indicated for obese patients and premenopausal women with undiagnosed right lower abdominal pain. Perforated appendicitis is not a contraindication to this procedure. I. Indications for surgery The indications for laparoscopic appendectomy surgery are similar to those for conventional surgery. 1. Acute appendicitis is the most important indication. This includes simple, purulent and gangrenous appendicitis of the head and body of the appendix. 2. Acute appendicitis is suspected in the right lower abdomen, especially in premenopausal women, and other diseases need to be excluded. 3, patients with chronic appendicitis and chronic right lower abdominal pain. The etiology of chronic right lower abdominal pain includes chronic appendicitis, chronic pelvic inflammatory disease, chronic adnexitis, endometriosis, Crohn’s disease, intestinal tuberculosis, etc. It is difficult to clarify the etiology of chronic right lower abdominal pain before surgery, and laparoscopic appendectomy allows a comprehensive view of the appendix, pelvis, adnexa and other organs of the abdominal cavity to prevent unnecessary appendectomy. 4. Perforated appendicitis. is not a contraindication to this procedure. Research data show that surgeons with extensive experience in traditional surgery and skilled laparoscopic techniques are fully competent for this procedure. 5. Laparoscopic appendectomy is also indicated for pediatric patients. To ensure the safety of the procedure, the involvement of a pediatric surgeon and special pediatric laparoscopic instruments are required. 6. The use of laparoscopic appendectomy in pregnant women with acute appendicitis has yet to be clinically studied. Some researchers have found that it is safe to perform the procedure in the first six months of pregnancy, after which the operation of laparoscopic surgery is affected by the enlargement of the uterus above the level of the umbilicus. Contraindications to surgery 1. A history of abdominal surgery in the last 2 years or other diseases that may lead to severe abdominal adhesions. 2, with heart and lung diseases and other important organs can not tolerate general anesthesia. 3.Patients with septal hernia. 4.Patients with coagulation disorders. 5.Women who are more than 6 months pregnant. 6.Patients with periappendiceal abscess, appendiceal mass, acute appendicitis combined with severe peritonitis and severe systemic infection.
