Heterotopic pancreas as a cause of intussusception: first case reported in Peru

Abstract

The heterotopic pancreas (HP) is a rare condition in the pediatric population. HP cases involving an ileal intussusception are rare in children and very rarely reported, usually presenting with symptoms of intestinal obstruction. We report the case of a one year old male patient with a chronic history of anorexia, irritability, abdominal pain, accompanied by intermittent episodes of "currant jelly" stools that evolved to rectal bleeding. The patient presented a concomitant diagnosis of allergic colitis, which prolonged the effective surgical treatment at an external health center. In the abdominal CT scan, the classic "target" sign was found. In the exploratory laparotomy an ileoileal intussusception was confirmed, a mass was found that the histopathology laboratory confirmed as HP. To our knowledge, it is the first case of pediatric intussusception by HP reported in Peru.
