Corrosive injury-induced gastric outlet obstruction: A changing spectrum of agents and treatment

Abstract

Methods: During the last 5 years, 61 children were admitted to the authors' hospital because of corrosive substance ingestion, and among them 6 patients were seen with gastric outlet obstruction. Two of them had ingested acid substances, and the other 4 had ingested alkali corrosives. The mean age was 2.9 years (range, 1.5 to 3). Their common complaint was postprandial vomiting, which had begun 3 weeks after the event (range, 1 week to 10 weeks). Endoscopic evaluation and barium contrast radiographies were performed at admission. Four patients had a pyloric stricture, 1 had an antral stricture, and another had an antropyloric stricture. Balloon dilatation of the pylorus tin 1 patient), pyloroplasty tin 3 patients), and Billroth procedures tin 2 patients) were performed. The mean follow-up period was 22 months (range, 6 weeks to 48 months). One patient, who had undergone a Billroth I procedure, underwent reoperation because of intestinal obstruction 3 months later. On follow-up they are all free of symptoms.
