Acute appendicitis is one of the very common acute abdominal diseases in clinical practice. At present, laparoscopic minimally invasive surgery is mainly used for appendectomy, and the specific steps are as follows: I. The patient is placed in a flat position, and after satisfactory general anesthesia, a laparotomy hole is established with the abdominal wall, minimally invasive surgical operating instruments are implanted, and an artificial pneumoperitoneum is established. Second, probe the abdominal cavity for large amounts of fluid and pus accumulation, as well as the severity of the appendix. Separate the adhesions between the appendix and the lateral abdominal wall, ileum and mesentery, and fully expose the appendix and appendiceal mesentery. After freeing the appendiceal artery, the appendiceal artery is clamped with a ligature, the appendix is double clamped at the root of the appendix, and the appendix and the appendiceal mesentery are removed together. V. After removing the appendix, clean the abdominal cavity to ensure that there is no obvious bleeding from the appendiceal stump, and the operation is finished.
