Two-Stage Endoscopic Resection Resolves Gastric Heterotopia Symptoms in BoyEndoscopic Surgery May Resolve Symptoms of Gastric Heterotopia in Children

Gastric heterotopia is a rare congenital condition in which gastric mucosa appears outside the stomach, most often in the duodenum. A new case report describes a 12-year-old boy who presented with chronic unexplained vomiting and symptoms suggesting partial upper intestinal obstruction. Endoscopic evaluation revealed a polypoid lesion in the duodenum, later confirmed as gastric heterotopia.

The patient underwent a two-stage endoscopic resection of the lesion. Following the procedure, his symptoms completely resolved, with no recurrence reported during follow-up. The authors note that complete resection may be achieved endoscopically in selected cases, offering a less invasive alternative to surgery.

This case highlights that polypoid duodenal gastric heterotopia should be considered in the differential diagnosis for children with persistent vomiting or signs of partial upper intestinal obstruction. Early recognition and appropriate endoscopic management can lead to symptom resolution and avoid more invasive interventions.

As a single case report, the findings cannot establish causality or generalizability. The small sample size limits broader conclusions, and no safety or long-term follow-up data were provided. Clinicians should weigh these limitations when applying the results to practice.
