The clinicopathological characteristics of gastric polyps and the relationship between fundic gland polyps, Helicobacter pylori infection, and proton pump inhibitors.

BACKGROUND

To explore the clinical characteristics of different types of gastric polyps and the relationship between fundic gland polyps, Helicobacter pylori (HP) infection, and proton pump inhibitor (PPI) use.

METHODS

The clinical data of 186 patients diagnosed with gastric polyps under endoscopy were selected for retrospective analysis, and the clinical data, gastroscopy, polyp histopathology, HP infection, and PPI usage of all subjects were analyzed.

RESULTS

Among the 186 patients with gastric polyps, there were significantly more women (131 cases) than men (55 cases), with a ratio of 2.38:1. PPIs were used in 78% of cases for more than 5 years. The pathological types of patients with gastric polyps in this study were fundic gland polyps, hyperplastic polyps, inflammatory fibrous polyps, and adenomatous polyps. Fundic gland polyps were mainly located in the fundus and gastric body, while hyperplastic polyps were mostly located in the gastric body (P<0.05). The positive rate of HP infection in patients with fundic gland polyps was significantly lower than that in patients with other types of polyps (P<0.05). In patients with long-term use of PPIs, the incidence of fundic gland polyps increased significantly (P<0.05).

CONCLUSIONS

There were significant differences among the different types of gastric polyps in terms of polyp position, shape, and size. The positive rate of HP infection in patients with fundic gland polyps was low. Long-term use of PPIs (>5 years) increased the incidence of fundic gland polyps to some extent. The mechanisms underlying the relationship between gastric polyps, HP infection, and the use of PPIs remain to be further studied.
