Gastric heterotopic pancreas in children: A prospective endoscopic study

Prospective study of 607 pediatric upper GI endoscopies found gastric heterotopic pancreas in 1.1% of children, with significantly higher prevalence in esophageal atresia patients (38%) and possible association with trisomy 21. Recognition of the characteristic 1-2cm umbilicated antral nodule is essential to prevent misdiagnosis and unnecessary intervention.
