Introduction: Colon polyps are proliferative and neoplastic lesions which originate from the mucosa, submucosa and protrude into the lumen. With this study, we aimed to reveal the demographic data, histopathological features, malignant potential and characteristics of patients with colonic polyp in our region by evaluating the results of 4-year colononoscopic polypectomy in our tertiary university clinic. Methods: The records of patients over 18 years of age with polyps detected during colonoscopy and removed by polypectomy between 2014 and 2019 in our hospital were retrospectively analyzed. The demographic characteristics of the patients, localization, size, number and histopathological features of the polyps, and control colonoscopy results were evaluated. Results: During this period, data of 240 polyps of 180 patients who underwent polypectomy in our clinic were analyzed. 125 (69%) of the patients were male and 55 (31%) were female. The average age of men was 59.2±14.4, and the mean age of women was 57.2±11.3. One hundred and thirty-seven people had a single polyp, 43 people had multiple polyps. When polyps are examined according to their localization; 27% was in the sigmoid colon, 24% in the rectum and 15% in the ascending colon. 82% of polyps were adenomatous polyp, 10% hyperplastic polyps, 3% adenocarcinoma, 3% inflammatory polyp. 67% of adenomatous polyps were tubular adenoma, 27% tubulovillous adenoma, 0.5% villous adenoma. 71% of adenomatous polyps had low grade dysplasia, 23% had high grade dysplasia. Adenocarcinoma was detected in 8 of the cases and intramucosal carcinoma was detected in 6% of the patients with adenomatous polyp. Colonoscopy controls were performed periodically in the cases, and recurrent polyps were detected in 52% and adenocarcinoma development in 2 patients. Conclusion: The colon polyps were observed in our study were more frequently in the 5th and 6th decades, and more frequently in men, as single or multiple neoplastic formations. It is most commonly located in the left colon and were found to be malign at a rate of 9%. Detection of cancer precursor polyps and their removal by polypectomy show the importance of colon cancer screening programs and colonoscopy.
