    Abstract:
    BACKGROUND/AIMS: Several previous studies suggest that eradication of Helicobacter pylori (H. pylori) leads to the disappearance of gastric hyperplastic polyps. However, little is known about the effect of H. pylori status and eradication on the recurrence of gastric polyps after endoscopic removal. Here, we investigated the recurrence of gastric polyps according to the final H. pylori status in patients who underwent endoscopic removal of gastric hyperplastic polyps. METHODS: Between January 2011 and December 2016, patients who underwent endoscopic removal of gastric hyperplastic polyps and were followed-up for more than two months were enrolled. The success of H. pylori eradication was assessed by histology and rapid urease test or urea breath test, at least 4 weeks after the completion of eradication treatment. At follow-up, the recurrence of gastric polyp was evaluated via esophagogastroduodenoscopy. RESULTS: Seventy-nine patients were enrolled. During the mean follow-up period of 16.4 months, the recurrence rate of gastric polyp was 25.3%. Among those who received H. pylori eradication therapy, the H. pylori persistent group showed a higher recurrence of polyp than the H. pylori eradicated group; but there was no statistical significance (42.9% vs. 21.7%, p=0.269). Regarding the final H. pylori infection status, the recurrence rate of gastric polyps was significantly higher in the H. pylori positive group than in the H. pylori negative group (42.9% vs. 18.9%, p=0.031). In multivariate analysis, the final H. pylori infection status was a significant risk factor for gastric polyp recurrence after endoscopic removal. CONCLUSIONS: The final positive H. pylori infection status is significantly associated with higher recurrence of gastric hyperplastic polyps after endoscopic removal.
