In brief
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.
Written by the GCMD Library team from the article.
Purpose
To document the prevalence and variable appearance of gastric heterotopic pancreas (HP) in children undergoing upper gastrointestinal (GI) endoscopy.
Methods
A prospective 4-year study of children undergoing flexible upper GI endoscopy in a single institution.
Results
A total of 607 upper GI endoscopies were performed in 478 pediatric patients during the 4-year period. Eleven children (6 girls, 5 boys) aged 2.9 to 16.9 years had endoscopic features typical of gastric HP. All but one lesion was located in the gastric antrum and most appeared as an umbilicated submucosal nodule measuring 1–2 cm in diameter. Five of 13 children with repaired esophageal atresia (EA) and two of nine children with trisomy 21 had gastric HP. The prevalence of endoscopically visualized gastric HP in children without a history of EA or trisomy 21 was 1.1%.
Conclusions
Gastric HP is present in about 1% of pediatric upper GI endoscopies. It is significantly more common in patients with EA and may also be associated with trisomy 21. Gastric HP typically appears as a single 1–2 cm antral submucosal nodule, usually with a central pit. Recognition of this lesion is important to avoid misdiagnosis and inappropriate treatment.
Level of Evidence
Level II (diagnostic).
