Duodenal intussusception secondary to hamartomatous polyps of the duodenum and a review of the literature

Abstract

Background: Hamartomas of the duodenum are benign duodenal tumors comprising approximately 5-10% of duodenal tumors. The incidence is < 0.01%. Typically asymptomatic, they may manifest as intestinal obstruction, gastrointestinal hemorrhage, biliary obstruction or intussusception. Intussusception as a manifestation of duodenal hamartoma is rare in itself with less than 200 cases reported in the literature. We present the first case report of duodenal intussusception presenting with a partial mid-gut volvulus and biliary obstruction. In addition, a review of current literature have been performed.
