Abstract

Intussusception is the leading cause for intestinal obstruction in children. However, it accounts for only 5% of bowel obstructions in adults. Heterotopic gastric mucosa (HGM) can occur anywhere in the gastrointestinal tract; nevertheless, its occurrence in the small intestine is rare unless associated with remnants of vitelline duct (Meckel's diverticulum). Herein, we describe a case of a 33-year-old male who presented with symptoms and signs of intestinal obstruction caused by ileo-colic intussusception, in which polypoid HGM acted as the organic lead point for intussusception. Several cases of intussusception caused by HGM have been reported in pediatric age group; however, this event is exceedingly rare in adults.
