Optimally, eradication success should be greater than 90%, but the recommended empirical reatments do not achieve these rates in real-life conditions. Objective: To determine the success rate of first-line empirical eradication treatment against H. pylori in pediatric patients treated in a tertiary hospital. Patients and Method: Retrospective descriptive study in patients with H. pylori infection detected in gastric biopsies and who had received first-line antibiotic treatment during the period 2017-2021.
