Heterotopic gastric mucosa leading to chronic jejunal obstruction

Abstract

Heterotopic gastric mucosa (HGM) has histologic features of gastric mucosa located outside of the stomach. The congenital form is a rare clinical entity that can present with GI bleeding, intussusception from a polypoid mass or intermittent obstruction. Ultrasound and upper GI series are typically used for diagnosis. We report a case of a young male with heterotopic gastric tissue presenting as numerous polyps causing intestinal obstruction.
