Recurrent duodenal diverticulitis after surgical resection of the diverticulum: a case report and literature review.

Duodenal diverticulitis has been considered a rare entity. The diagnosis with computed tomography has become a fast and noninvasive means of detection and guide to management. Cases of surgically resected duodenal diverticula reforming and reinfecting are rarer yet, often presenting with similar symptoms. Duodenal diverticulitis can present with a wide range of symptoms mimicking anything from gastritis to acute abdomen, or as in the case of our patient, as mid abdominal pain with newly developed liver abscess. According to the literature, duodenal diverticula are incidentally discovered at a rate of 5% to 10% in living adults and in up to 22% at autopsy.
