Extensive gastric heterotopia of the small intestine resulting in massive gastrointestinal bleeding, rowel perforation, and death: Report of a case and review of the literature

Gastric heterotopia of the small intestine is a rare occurrence outside of Meckel's diverticulum and intestinal duplication. The vast majority of case s of gastric heterotopia occur as polypoid or tumorous lesions in the duode num. These lesions have been associated with clinical symptoms including di arrhea, obstruction, dyspepsia, ulceration, and gastrointestinal bleeding. We present a case of gastric heterotopia that is unique because the lesions occurred as multiple, carpet-like, nonpolypoid areas throughout a large po rtion of the small intestine. A review of the literature is included.
