Aim: Polyps are one of the most common pathologic indications observed in the lower gastrointestinal system. Colonoscopic polypectomy ensures both the treatment of such lesions and identification of their histopathologic features. The purpose of this study was to evaluate the results of polypectomies performed in our clinic. Method: Colonoscopy reports produced and archived in the Endoscopy Unit of the Faculty of Medicine of Dicle University between January 2010 and December 2014 were retrospectively examined. Demographic, colonoscopic and histopathologic data of 470 patients who underwent polypectomy were recorded. Results: In five years (between January 2010 and December 2014) a total of 3514 patients underwent colonoscopy and 470 of them were found to have at least one polyp (13.3%). The patients’ mean age was 56.9±16.0 years (15-100, range) and 270 of them (61.7%) were male. A total of 980 polypectomies (polyp numbers; median=2, minimum-maximum=1-15) were performed for polyps varying between 2-40 mm in size (mean 6.24±5.0 mm). 31.3% of the patients had polyps in multiple locations, however the most frequent location of the polyps was the rectum (44.9%). The polyps were grouped according to their histopathologic features: adenomatous (53.6%), hyperplastic (31.7%), cancerous (6.6%), dysplastic (5.1%) and others (3%). The histopathologic malignancy risk was found to correlate with having polyps larger than 20 mm in diameter, having pedunculated polyps and having polyps in multiple locations (p<0.001, p<0.001, and p=0.011, respectively). In addition, a correlation was found between the histopathologic dysplasia risk and polyps located on the right side of the colon (p=0.033). Conclusion: Polyp was observed for significant portion of our patient who underwent colonoscopy. The most common of these polyps were the adenomatous type which has the potential of malignancy.
