Acute appendicitis is relatively common in clinical practice with severe symptoms. Compared to chronic appendicitis, acute appendicitis can cause the appendix tube to become purulent and perforate, leading to a widespread peritonitis. Severe peritonitis can cause multi-organ failure and even shock. Chronic appendicitis, on the other hand, mainly manifests as chronic abdominal pain and seldom shows signs of appendix perforation. It primarily leads to an abscess around the appendix, encapsulating the appendix and causing repetitive chronic pain, which is difficult to heal. Both acute and chronic appendicitis should be treated surgically by removing the appendix to achieve a complete cure.
