Recurrent intestinal intussusception in an adult due to intestinal pseudopolyps not associated with inflammatory bowel disease: a case report

Abstract

Intestinal intussusception in adults is very rare, and only accounts for approximately 1 % of cases. Unlike in children, in whom intussusception is of an idiopathic etiology, in adults the condition is due to an organic condition in a majority of cases (more than 90 %). Small bowel intussusception is more commonly due to a benign cause, while the opposite occurs with large bowel intussusception. Giant intestinal pseudopolyps are also uncommon and are usually associated with mucosal changes in inflammatory bowel disease. The lack of association of these pseudopolyps with ulcerative colitis or Crohn's disease is exceptional. They are also an exceptional cause of recurrent intestinal intussusception, an association which has never been reported in the literature to the best of our knowledge.
