Gastric Antral Mucosal Changes in Children With Intestinal Metaplasia

Academic Article


  • Objectives: The gastric mucosal change accompanying gastric antral intestinal metaplasia (IM) in the pediatric population and its clinical implications remain unclear. Methods: We retrieved all patients younger than 18¬†years who had upper GI endoscopy with a pathology diagnosis of antral IM between 2009 and 2020. Each biopsy was evaluated for the presence of dysplasia, Helicobacter pylori, gastritis, and other pathologic changes. Results: A total of 134 patients with antral IM were identified; 72 (53.7%) with coexisting pathology including chronic gastritis (n = 22), reactive gastropathy (n = 16), focal mild chronic inflammation (n = 13), gastric eosinophilia (n = 9), chronic active gastritis associated with (n = 2) and without Helicobacter infection (n = 3), and others (n = 7). The remaining 62 (46.3%) showed isolated IM. Gastric IM increased with age, and was often accompanied by other pathologic changes, especially in female children. Twenty-seven patients had follow up biopsies; 11 of the 27 patients (40.7%) showed persistent IM in at least one repeat biopsies. None demonstrated dysplasia. Conclusions: In children, antral IM increases with age and often coexists with other pathologic changes. Gastric IM could persist for at least months to years in a significant subset of patients with chronic gastritis and gastric eosinophilia.
