Background There is increasing evidence that the eradication of Helicobacter pylori leads to the regression of gastric hyperplastic polyps (GHPs). We performed a systematic review with a meta‐analysis of randomized controlled trials and observational studies that assessed the effects of eradication. Materials and Methods We searched the PubMed, Embase, and Cochrane Central Register of Controlled Trials databases for relevant studies with a combination of the terms “ Helicobacter pylori ” and “polyps.” The risk ratio was used to compare the effect of H . pylori eradication/treatment on GHP. We also calculated the pooled disappearance rate of GHP in the H . pylori eradication/treatment group and persistent infection group. Results We analyzed data from 6 studies, including 3 RCTs. A total of 58/394 patients were included in the H . pylori treatment/successful eradication group, and 57/302 patients were included in the H . pylori untreated/persistent infection group. The pooled rate of GHP elimination after H . pylori treatment/successful eradication was 59% (95% CI, 43%‐75%)/79% (95% CI, 72%‐86%). H . pylori treatment/successful eradication significantly increased the GHP elimination rate [ITT: (pooled rate: 58% vs. 0%, RR =22.24, 95% CI, 4.51– 109.78, p = 0.0001), PP: (pooled rate: 65% vs. 0%, RR =22.25, 95% CI, 4.52– 109.37, p = 0.0001)/(pooled rate: 79% vs. 9%, RR =26.87, 95% CI , 1.34–540.5, p = 0.03)]. Conclusions Our meta‐analysis showed that after the eradication of H . pylori , most GHPs are eliminated. Moreover, the treatment/successful eradication of H . pylori increased the GHP elimination rate by more than 20 times that in the control group.
