title: Induction of gastroduodenal prolapse by antral heterotopic pancreas.
abstract: Ectopic pancreas is the most common congenital anomaly in the gastric antrum. In some patients, there is a distinct tendency for this lesion to produce intermittent crampy abdominal pain by provoking gastroduodenal prolapse. This condition should be considered after a more distal prolapse from intussusception is excluded. An upper gastrointestinal series performed during an episode of symptoms may be diagnostic of this entity.
