Perforated appendicitis does not require intestinal resection, and its treatment depends on the patient’s condition. Perforated appendicitis is often associated with diffuse peritonitis and infectious shock, so it requires anti-infective and anti-shock treatments, and the surgery requires appendicectomy, which does not require intestinal resection. When the appendix becomes septic or ischemic, it is easy to perforate the wall of the appendix. For smaller perforations, an appendiceal abscess tends to form after the greater omentum is encircled, and anti-infective therapy is given with elective appendectomy. Some patients may develop diffuse peritonitis, which may even lead to infectious shock, requiring prompt anti-infective and anti-shock treatment. At the same time when the patient carries on the anti-infection and shock treatment, it is necessary to perfect all the preoperative examinations and make good preoperative preparations, and after the patient’s condition is stabilized, appendicectomy will be given in time, because the intestinal tube does not have the relevant lesions, so it is not necessary to resect the intestinal tube. It is recommended that the patient consult a doctor in a timely manner, improve the auxiliary examination, clarify the condition, and give appropriate treatment measures by a professional physician for the patient’s condition.
