“Introduction: Helicobacter pylori is a bacterium that lives in the gastric epithelium and can cause gastritis, peptic ulcer and gastric cancer. It is considered the most prevalent chronic infection worldwide. It can persist throughout life and be responsible for multiple digestive and extradigestive diseases. Objective: The main objective of the study was to evaluate the utility of the gastric mucosal surface pattern for the detection of Helicobacter pylori. Methods: An observational, analytical, cross-sectional, diagnostic test study was carried out in 232 patients in a third level public hospital in Peru. An OLYMPUS GIF HQ-190 endoscope was used to assess the gastric mucosal surface pattern. In each patient in the study, biopsies of the gastric antrum and body were obtained for anatomopathological study in search of Helicobacter pylori. Results: 232 patients were evaluated, 153 of them had H. pylori and 79 did not present the infection. Most of the patients were female. The sensitivity, specificity, positive predictive value and negative predictive value to detect Helicobacter pylori using the gastric mucosa surface pattern was 92.81%, 40.51%, 75.13%, 74.42% respectively. The positive and negative likelihood ratio values were 1.56 and 0.18. Conclusions: The gastric mucosa surface pattern is not useful to detect Helicobacter pylori“
