Frequency and risk factors of gastric and duodenal ulcers or erosions in children: a prospective 1-month European multicenter study

Abstract

Although limited by the short-time duration and the heterogeneity of the patients included throughout the 19 centers, our study shows a frequency of 8.1% of ulcers and/or erosions in children, occurring mainly in the second decade of life. H. pylori infection and gastrotoxic medications were less frequently implicated than expected.
