Abstract:

INTRODUCTION: To contribute to the literatüre, the demographic features, frequency, histological features, size and location of polyps examined during 10 years were evaluated. METHODS: Reports of 5561 colonoscopy procedures performed between 2008 and 2018 were reviewed retrospectively. Statistical analysis was made. RESULTS: Polyps were found in 1835 (32.9%) of the 5561 whom colonoscopy performed. Of the patients with polyps, 16.1% were <40-years-old, 43.9% were between 40 and 60-years-old and 39.8% were over 60-yearsold. The mean age of patients with polyps was 57 ± 78 years, and those without polyps were 51 ± 35 years. 37.6% of those with polyps were female and 62.4% were male. In histopathological examination, 37.38% of the polyps were found hyperplastic polyps, 55.9% adenomatous, and 6.7% adenocarcinoma. Of the adenomatous polyp (1026) cases, 48.8% were tubular, 44.5% were tubulovillous, and 6.6% were villous. The number of those with a polyps >1 cm was 1491 (81.3%), the average age was 54.47, while those larger than 1 cm were 344 (18.7%) and the average age was 58 ± 12. The percentage of polyp detection in men (62.4% vs. 37.6%) and the frequency of detecting >1 cm polyp (22.09% vs. 13.18%) were higher than in women. The most common location of polyps was the rectosigmoid region (1053 patients [57.38%]). Malignancy risk and size increased with age. DISCUSSION AND CONCLUSION: In our study, the frequency of polyps increased with age in both genders. The prevalence of polyps detected was higher than the literature. This shows the importance of widespread and timely colonoscopic examination.
