Appendicitis is a very common surgical condition, and open appendectomy is a classic and well-established procedure for the treatment of acute appendicitis. Some people think that the surgical incision is only 4-6 cm, and the surgical trauma is light, so it seems unnecessary to perform laparoscopic surgery. In fact, laparoscopic appendectomy itself has many advantages: 1, has the dual function of diagnosis and treatment: in clinical medical work, sometimes doctors face patients with right lower abdominal pain of unknown diagnosis (especially young female patients) and are uncertain whether to take active surgical treatment. Laparoscopy is not limited by small incisions can fully explore the abdominal cavity, can find the combined lesions in the abdominal cavity, and can complete joint surgery; laparoscopic search for the appendix is easy, and intraoperative exploration under direct vision can reduce the rate of misdiagnosis and misincision of appendicitis. 2.Less complications and fast postoperative recovery: the operator’s hand operates outside the body and does not enter the body, and what enters the body is only tiny and fine surgical instruments, avoiding the pulling of open surgical instruments, reducing the damage to the plasma membrane layer of the organs in the abdominal cavity, and reducing the incidence of intestinal adhesions and intestinal obstruction. Postoperative specimens are removed by puncture sheath tubes or via specimen bags without contact with incisional tissues, avoiding contamination of the incision and reducing the common and nasty incisional infections after open appendectomy. The hospitalization time is short, generally 2 to 3 days after surgery can be discharged, a week after resuming normal life and work. 3.Aesthetic effect of abdominal wall: In traditional appendectomy, for obese patients or patients with difficulty in finding appendix, it is often necessary to extend the incision to complete the operation and leave permanent scars on the abdominal wall after the operation. Laparoscopic surgery requires only three 5-10 mm abdominal wall poke holes, which are scattered and concealed and do not affect the aesthetics after healing. The Trocar (poke hole) location is well chosen and will not be visible even if a three-pointed piercing is worn. Which patients are suitable for laparoscopic appendectomy? 1, Acute appendicitis is the main indication, including simple, purulent and gangrenous appendicitis of the head and body of the appendix. 2, Acute right lower abdominal abdomen suspected to be acute appendicitis, especially in premenopausal women, who need to exclude other diseases. 3, Patients with chronic appendicitis and chronic right lower abdominal pain.
