Appendicitis is divided into simple appendicitis, suppurative appendicitis and gangrenous appendicitis according to the detailed condition and type of pathology. If the appendix is septic, there is usually significant exudation on the plasma membrane surface. In this case, the examination will reveal localized signs of peritonitis, i.e., pressure pain, rebound pain and muscle tension. The patient’s blood tests will show a significant increase in the percentage of leukocytes and neutrophils, and the patient’s pain symptoms will progressively worsen. The purulent appendiceal plasma membrane surface exudate will also be further verified and confirmed during surgery. During surgery, a detailed debridement of the abdominopelvic cavity is performed to avoid residual purulent effusion complicating infection.
