Helicobacter pylori–Induced Gastroduodenal Stricture in a Child

Abstract

ABSTRACT Helicobacter pylori is a known cause of peptic ulcers, but it has not been reported to cause strictures in children. We present the case of a previously healthy 12-year-old boy with sudden onset of abdominal pain and vomiting, positive stool H. pylori antigen testing, and esophagogastroduodenoscopy revealing a gastroduodenal stricture causing gastric outlet obstruction. Because of medically refractory disease, he ultimately required laparoscopic truncal vagotomy with open pyloroplasty. This is an unusually severe presentation and may warrant H. pylori being on the differential of pediatric gastrointestinal strictures as well as further discussion on other long-term implications.
