A serious conundrum for surgeons: Stump appendicitis.

Stump appendicitis is an acute inflammation of remnant appendix, a rare complication of incomplete appendectomy. It may present as acute abdomen with history of appendectomy, which may cause delay in diagnosis. Therefore, incomplete appendectomy should be considered as a differential diagnosis of acute abdomen in patients with medical history of appendectomy. The present case is one of stump appendicitis 6 months after appendectomy. Stump appendectomy was performed and the patient was discharged 7 days after the operation without any complication.
