Chronic appendicitis can achieve good treatment outcomes through active surgical treatment or conservative treatment, and the cases of appendicitis here are not severe. However, a very small portion of patients with chronic appendicitis, especially those with underlying diseases such as diabetes, are at risk of developing a purulent infection of the appendix, which can lead to perforation of the appendix and result in diffuse peritonitis, sepsis, septic shock, and multiple organ failure. Thus, it can be said that there are indeed a few severe cases among patients with chronic appendicitis.
