Abstract

Objective. To determine the frequency of infection by Helicobacter pylori (HP) and premalignant gastric lesions (PGL) in patients with non-studied dyspepsia, in a general hospital
in Lima. Material and methods. It was carried out a descriptive, cross-sectional, retrospective study. The study population corresponded to outpatients referred to the Hospital EsSalud Uldarico Rocca Fernandez, Villa El Salvador, Lima, with a diagnosis of non-studied dyspepsia, who underwent upper gastrointestinal endoscopy between April 2012 and March 2014. Clinical and anatomopathological characteristics were evaluated. Results. 2 790 patients were studied, average age 48,6 (SD ± 15,3) year-old, range: 14-91 year-old. We found a global frequency of HP infection in 61,3 % (95%CI: 59,5-63,1) and premalignant gastric lesions in 23,6 % (95%CI: 22-25,1). A statistically significant association was found between patients with positive HP and PGL (chi square = 14,6, p < 0,01). The HP infection was 62,5% in those who had atrophic gastritis), 64,6 % in those with complete intestinal metaplasia, 56,8 % in those with incomplete intestinal metaplasia and 32,5 % in those with dysplasia. Conclusions. The frequency of Helicobacter pylori (HP) infection and premalignant gastric lesions was high in patients with non-studied dyspepsia undergoing endoscopy in the study population; and, only a significant association was found between HP with complete intestinal metaplasia and dysplasia.
