    IntroductionThe diagnosis of atrophic gastritis (AG) and intestinal metaplasia (IM) is a crucial screening and surveillance strategy for gastric adenocarcinoma.ObjectivesThe main objective was to assess the performance of endoscopic diagnosis of gastric precancerous conditions in a real‑life scenario.Patients And MethodsA total of 2099 gastroscopies with biopsy to evaluate gastritis performed in 3 endoscopic centers from March 2018 to October 2019 were retrospectively analyzed. Endoscopic data regarding gastritis, atrophy, and intestinal metaplasia were compared with histopathological reports.ResultsThe endoscopic diagnosis sensitivity was 69.5% for AG and 19.4% for IM. The specificity of endoscopic detection of AG was 69.5% and of IM, 97.9%. The endoscopic detection of gastritis was a risk factor for AG and IM diagnosis (odds ratio [OR], 5.1; 95% CI, 1.9-14.1 and OR, 14.5; 95% CI, 5.9-35.8, respectively) and the patient's age was a risk factor for AG, IM, dysplasia, and advanced stage of AG (ASAG) diagnosis (OR, 1.05; 95% CI, 1.04-1.06; OR, 1.035; 95% CI, 1.03-1.04; OR, 1.04; 95% CI, 1.02-1.06; and OR, 1.05; 95% CI, 1.02-1.09, respectively). The age threshold of 45 or 40 years with endoscopically diagnosed gastritis for obtaining biopsy would result in 96.3% and 95% ASAG or dysplasia diagnosis sensitivity, and in the reduction of the number of biopsies by 20.2% and 20.5%, respectively.ConclusionsThe application of the age threshold with or without an endoscopic diagnosis of gastritis could reduce the number of mapping biopsies to detect advanced stages of atrophic gastritis or dysplasia with high sensitivity.
