COMPLICATED DUODENAL DIVERTICULA: INDICATIONS FOR OPERATIVE MANAGEMENT

Objectives: The duodenum is the second most common location for a diverticulum to form after the colon. These duodenal diverticula (DD) are often found incidentally and rarely require intervention. In recent years, surgical management has been restricted to patients with significant complicated sequelae, such as perforation, abscess, or fistula formation.

We present the rare case of a perforated broad-based diverticulum in the third portion of the duodenum necessitating surgical correction. The patient presented with persistent symptoms following failure of conservative management and underwent surgical resection. Due to difficulty visualizing the extent of the diverticulum, a novel intraoperative technique of bowel insufflation via nasogastric tube was used allowing for elucidation of the diverticular borders and complete resection.

Although DD are common, there exists no consensus on when operative intervention is indicated. Given that significant morbidity and mortality can be associated with symptomatic DD, a systematic way to guide management decisions is needed. We propose that the modified Hinchey classification can be used not only to categorize duodenal diverticulitis, but to guide treatment choice in cases with unclear risk benefit profiles.
