Core Tip

Core tip: This study investigated the association of gastric Helicobacter pylori (H. pylori) infection with the risk of colorectal polyps and colorectal cancer (CRC). The results indicated that patients with H. pylori infection were 2.19 and 3.05 times more likely to develop colorectal polyps and CRC, respectively, than those without H. pylori infection. The prevalence of H. pylori infection was higher in the patient group with multiple polyps and colorectal adenomas than in those with a solitary polyp and non-adenomatous polyps, respectively. Gastric H. pylori infection and H. pylori-associated atrophic gastritis or intestinal metaplasia elevated the risk of colorectal polyps and CRC. Therefore, earlier and frequent colonoscopy is necessary.
