It was aimed to investigate whether the Helicobacter pylori infection is related to the frequency, localization, size and number of colorectal polyps. The data of 4561 patients who underwent esophagogastroduodenoscopy and colonoscopy were analyzed retrospectively. Patients with and without polyps at colonoscopy were grouped and the frequency of H pylori infection was compared in these patients. The relationship between the groups was evaluated with statistical methods. It was determined that the rate of H pylori infection was higher in patients with colorectal polyps than in patients without polyps (P < .005). Patients with multiple polyps, polyps larger than 1 cm, and tubulovillous and villous adenoma from polyp types had a higher rate of H pylori infection (P = .095; P .004; P .001). When the polyps were evaluated according to their localization, H pylori infection rates were not different between the groups (P = .341). It has been observed that the rate of H pylori infection is higher in large polyps, multiple polyps, tubulovillous and villous adenomas, which are known to have a higher risk of malignancy.
