Objective To explore the trend of gastric polyps from 2012 to 2019 and its clinical and pathological characteristics.

Methods Totally, 90 643 patients of gastroscopy and pathological reports of gastroscopy in Ningxia People's Hospital from October 2012 to October 2019 were collected. Age, sex, location, size, number of polyps, complications, Helicobacter pylori (Hp) detection results, and pathological results were retrospectively analyzed. The χ² test was used for statistical analysis.

Results A total of 3 807 cases of gastric polyps were detected by gastroscopy in 90 643 cases, with a detection rate of 4.2%. 1 170 cases of gastric polyps were confirmed by biopsy. Among them, women were more common (1.7:1). The ages of patients were mostly between 30 and 60 years old. The predilection sites were mainly in the gastric body (45.8%). Among them, adenomatous polyps with the size of more than 5 mm are more common, while polyps of other pathological types with the size of less than 5 mm are more common, mostly single. Adenomatous polyps and inflammatory polyps are more common in patients with atrophic gastritis. Fundus gland polyps and proliferative polyps are more common in patients with non-atrophic gastritis. The overall infection rate of Hp is 20.0%, proliferative polyps (27.9%), and inflammatory polyps. The incidence of atypical hyperplasia was significantly higher in adenomatous polyps than in other types of polyps (32.0%). The proportion of fundic gland polyps increased to 50.2%, and the proportion of inflammatory polyps decreased from 64.5% to 10.5%.

Conclusions The pathological spectrum of gastric polyps has changed in the past seven years, and fundic gland polyps have become the most common pathological type. Whether all polyps should be resected or not needs further evaluation according to their clinical and pathological characteristics.
