Chronic appendicitis does not usually require emergency surgery. Chronic appendicitis is the result of recurrent episodes of acute appendicitis that have improved with conservative treatment. Chronic appendicitis can be temporarily treated with anti-infective symptomatology and can be continued with conservative treatment after the symptoms have subsided. If chronic appendicitis has repeated attacks and affects work, study and other life, surgery is recommended. The surgical procedure can be either open or minimally invasive. In addition, chronic appendicitis needs to be examined before diagnosis, and the examination is mainly a CT examination of the lower abdomen. Colonoscopy of the intestine is also performed to detect other diseases of the intestine.
