Case. A 3 year-old boy was admitted with non-bilious vomiting and abdominal distention. Abdominal X-ray showed gastric air-fluid level and ultrasonography showed 5 cm intussusception at right upper quadrant. Upper gastrointestinal study showed gastric outlet obstruction. Multiple polyps at stomach and pylorus were detected in endoscopy. The explorative laparotomy revealed polyps originating from pylorus passing to duodenum and causing PDI. The polyps were excised to reduce the intussusception via duodenotomy.

Conclusion. PDI and pyloric polyps should be kept in mind in cases with radiological examinations revealing gastric outlet obstruction. Keywords : intussusceptions, pylorus, gastric outlet obstruction, polyps
