Delayed pathology of the appendiceal stump: a case report of stump appendicitis and review.

Abstract

A case of right lower quadrant pain in a 53-year-old postmenopausal female who underwent appendectomy 21 years previously is presented. Recurrent appendicitis with rupture was noted in the appendiceal stump on exploratory celiotomy after diagnosis by computed tomography scan. Although rare, pathology of the appendiceal stump, whether inverted or not, is a real entity that can be encountered on laparotomy. Malignancy and hemorrhage can also occur in the appendiceal remnant, but the large number of disorders that can cause acute right lower quadrant abdominal pain makes appendiceal stump pathology extremely difficult to detect preoperatively. Because of the extensive differential diagnosis, timely operative intervention for clinical peritonitis in this region should not be delayed.
