Abstract

Corrosive ingestion may result in severe gastrointestinal injury and subsequent benign pyloric stenosis. Although endoscopic balloon dilatation is considered first-line therapy, recurrence is common because of fibrotic scar remodeling. We report a young adult with corrosive-induced pyloric stenosis who developed progressive gastric outlet obstruction and severe malnutrition. Despite multiple sessions of endoscopic balloon dilatation and temporary stent placement, recurrent stenosis occurred. The patient subsequently underwent balloon dilatation combined with intralesional triamcinolone injection. Following two sessions of steroid-augmented dilatation, sustained clinical improvement was achieved. The patient resumed oral intake, gained weight, and follow-up endoscopy demonstrated complete resolution of the stricture. Intralesional steroid injection may be an effective adjunct to balloon dilatation in selected patients with refractory benign pyloric stenosis, potentially avoiding surgical intervention.
