Recurrent gastrointestinal tract bleeding secondary to jejunal gastric heterotopia.

A 4-year-old Latino boy with a history of malrotation, nonobstructing annular pancreas, and a Ladd procedure during infancy presented with recurrent severe gastrointestinal tract bleeding. Investigations revealed a large mass in the proximal small bowel. At laparotomy, the proximal jejunal segment containing the mass was resected. Pathological examinations revealed a large intraluminal polyp composed of ectopic gastric mucosa. The patient presented 10 months later with recurrent bleeding, and subsequent laparotomy demonstrated a newly acquired segment of jejunal polyposis not present at the first operation. The case is presented, along with a plan of patient surveillance and a review of the pertinent literature.
