Non-hypertrophic gastric outlet obstruction in the paediatric population: a case series with focus on management

Abstract

Background Non-hypertrophic gastric outlet obstruction (GOO) in children is rare and usually presents beyond infancy. Aetiology is variable, and management is not well established due to its rarity. Methods We aimed to conduct a descriptive study of these cases within our geographic area. It is a retrospective chart review of all children with non-hypertrophic gastric outlet obstruction presenting to three hospitals in northwest Syria during the period 2019–2023. Demographics, presentation, and management data were extracted. Results Twelve cases were identified, eight males, with age range 1–12 years and follow-up range 3–42 months. Eight patients had a history drinking battery acid and one with ingestion of high-dose ibuprofen. The other three had no clear aetiology. Five patients improved by endoscopic balloon dilatations (EBD), and seven needed surgeries. All those who had successful EBD were treated within 3 weeks of ingestion. Conclusion Non-hypertrophic GOO in children is rare and mostly related to caustic material ingestion. Treatment by endoscopic balloon dilatation is likely to be successful if done within 3 weeks from caustic ingestion. After that period, often surgery is needed.
