Perforation of the appendix should be promptly followed by the option of surgery for dissection. Patients with perforated appendix will have obvious symptoms of abdominal distension, abdominal pain, nausea and vomiting, and fever may be present. On physical examination, there is a typical manifestation of peritonitis, with pressure pain, rebound pain and muscle tension in the right lower abdomen, and even diffuse peritonitis in some cases. At this time, surgical dissection should be chosen immediately to remove the necrotic appendix of the patient, and special attention should be paid to the thorough removal of exudate or purulent fluid from the abdominal and pelvic cavities during the operation to avoid the formation of abscesses after the operation. Patients should be actively treated with anti-infection therapy, usually penicillin combined with metronidazole intravenously, and adequate fluid supplementation and nutritional support should be provided. Patients should be advised to get out of bed early to promote the recovery of intestinal peristaltic function, and to perform regular incisional dressing changes and stitch removal.
