Heterotopic gastric mucosa (HGM) may be located at sites throughout the gastrointestinal tract. HGM usually occurs in the oesophagus, duodenum, Meckel's diverticulum and intestinal duplication. But they are rare beyond the small intestine except for its association with Meckel's diverticulum.HGM can cause abdominal pain, gastrointestinal bleeding, intestinal obstruction, intussusception, intestinal perforation. Complication of perforation is rare.A case of HGM in small bowel presenting with recurrent small intestine perforation is reported to improve clinicians' understanding of HGM in small bowel.
