Abstract: Objective To analyze the clinical, gastroscopic and pathological characteristics of gastric polyps (GPs) and their correlation with helicobacter pylori infection (Hp). Methods A total of 440 GPs cases confirmed by endoscope and biopsy were recruited. The differences in age, site, size and Hp status of GPs according to various pathological types and sex were analyzed. Results The incidence of GPs increased with age. Fundic gland polyps (FGPs) were more likely to be found in female. The number of FGPs, hyperplastic polyps (HPs), inflammatory polyps (IPs) and adenomatous polyps (APs) was 274, 138, 26, and 2, respectively. The number of polyps in cardia, fundus, body, antrum and pylorus was 22, 234, 106, 75 and 3, respectively. The number of polyps <1 cm, 1-1.9 cm, and ≥2 cm was 392, 40 and 8, respectively. A total of 372 GPs were checked for Hp with tissue slice dyeing. FGPs, HPs, IPs and APs cases with Hp positive was 0, 57, 9, and 1, respectively. There was difference in size of GPs according to various sites (P<0.05). There were differences in site, size and Hp status of GPs according to various pathological types (P<0.05). Conclusion The spectrum of GPs pathology changes. HPs correlates with Hp positively; however, FGPs correlates with Hp negatively. Characteristics of gastric polyps are helpful for preliminary judgment of GPs during gastroscopy, guidance of therapy and follow-up.
