A recurrence of appendicitis six months after surgery is usually recommended for another surgical procedure. If there is still pain in the right lower abdomen, the examination suggests a recurrence of appendicitis. It may be that the inflammation of the appendix was so severe during the last surgery that the appendix was not completely freed, and a part of the appendix was removed, leaving the root of the appendix, which led to recurrence of appendicitis at the root. Patients with appendicitis who experience a recurrence six months after surgery are clinically referred to as appendiceal stumpitis, which is a manifestation of inflammation in the appendiceal stump. In this case, it is usually recommended to opt for another surgical procedure to remove the appendiceal stump and, if necessary, also to remove the ileocecal portion of the appendix and repair and suture the intestinal canal. If appendicitis reoccurs, the patient should go to a regular hospital in time to have the cause of the reoccurrence diagnosed by a specialized doctor, and take targeted measures.
