Here we aim to test the diagnostic role of conventional NBI (C-NBI) in identifying Helicobacter pylori (HP) infection, severity of gastritis, and gastric atrophy. Methods: Initially, the endoscopic records of 300 patients were retrospectively searched for specific C-NBI gastric mucosal patterns, where five different C-NBI mucosal patterns were identified. In a second step, 20 patients with different C-NBI mucosal patterns were subjected to gastric mucosal biopsy for HP testing and histopathological assessment. Results: Five different histopathological grades of HP gastritis, in terms of grade of gastric atrophy, intestinal metaplasia, infiltration by inflammatory cells, and density of HP infection, were recognized among the different C-NBI mucosal patterns. Conclusions: C-NBI seems to be a promising method for HP infection identification and gastric cancer risk stratification of patients.
