Prolapsed hyperplastic gastric polyp causing gastric outlet obstruction, hypergastrinemia, and hematemesis in an infant.
An infant presented with hematemesis and gastric outlet obstruction. Preoperative diagnosis of duodenal duplication cyst was based on a collaboration of radiological studies. At exploration the patient was found to have a gastric polyp that had intussuscepted into the duodenum leading to obstruction and hypergastrinemia secondary to gastric mucosa in the duodenal alkaline environment.
