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.
