Objetive: To determine the frequency of Helicobacter pylori infection and describe the clinical characteristics of children with upper endoscopy from the service of Gastroenterology - Hospital Nacional Almanzor Aguinaga Asenjo - ESSALUD: 2007 - 2010. Materials and Methods: Retrospective, descriptive study in which the medical records and the endoscopy sheet of 93 patients younger than 18 years, were reviewed. Descriptive statistics was used. The processing of data was using Microsoft Excel 2010 and 10.0th STATA version. Results: There were 93 patients of whom 60 were women (64.52%) and 33 males (35.48%). The mean age was 12 +/- 4 years. The frequency of Helicobacter pylori infection was 68.82%. In patients with Helicobacter pylori infection the primary indication for endoscopy was "gastritis" followed by nonspecific abdominal pain. In HP positive patients, the principal indication for endoscopic was "gastritis" 50.54%, follow with Abdominal recurrent pain with 24.73%. The most frequent endoscopic diagnosis in HP patients was nodular gastritis: 31 patients (33.33%), the main histopathological finding was moderate chronic follicular gastritis: 55 patients (59.14%). Association between Nodular gastritis (p.0,044) and Chronic folicular moderate Gastritis (p< 0,001) with the presence of Helicobacter pylori, was found. Conclusions: Helicobacter pylori infection in children under 18 years was very frequent, being Nodular gastritis and Chronic follicular moderate gastritis the endoscopic and biopsy findings, more frequently found. We found an association within Helicobacter pylori infection with Nodular gastritis and Chronic moderate follicular gastritis. [ABSTRACT FROM AUTHOR]
