Objective: To explore the detection rate of gastric polyp (GP) in Shanghai and analyze its clinical characteristics. Methods: A total of 36 857 subjects undergone gastroscopy during December 2012 to May 2019 were enrolled, and the detection rate of GP and related pathologic data were analyzed. Results: It revealed that 3 858 patients had GP, with a detection rate of 10.47%. In patients over 60 years old, 1 534 patients were diagnosed as having GP, with a detection rate of 14.75%. Compared with patients in other age groups (<30, 30-39, 40-49, 50-59 years), the constituent ratio of patients with GP diameter ≥2.0 was higher(1.8%)(P<0.05), so was with adenomatous polyps (1.9%) and with intraepithelial neoplasia (2.9%)(P<0.05). The only three cases with high-grade intraepithelial neoplasia were all ≥60 years old. Besides, the constituent ratio of patients ≥60 years old with atrophic gastritis and with intestinal metaplasia were 22.4% and 34.0%, respectively,which were higher than those of patients <60 years old. In contrast, GP patients ≥60 years old had a lower constituent ratio of Helicobacter pylori infection (15.1%), lower than that of patients under 60 years old (P<0.01). Conclusions: In comparison with the population <60 years old, population ≥60 had a higher detection rate of GP. GP patients of ≥60 years old had higher proportion of polyps diameter greater than 2 cm, adenomatous polyps, intraepithelial neoplasia, atrophic gastritis, and intestinal metaplasia. Therefore, more attention should be paid to the detection and pathology examination of GP in elderly patients.
