Core Tip

Core tip: One of the major reasons for colonoscopy is detection of colon polyps, such as adenomas. Early diagnosis and endoscopic removal of adenomatous polyps is one of the main objectives for screening and prevention of colorectal cancer (CRC). Given that, only few studies are available in the national literature regarding the assessment of colorectal polyps, but none has explicitly noted the rate of polyp detection. Nevertheless, our study provides comprehensive information about clinical and epidemiological features of colorectal polyps. Therefore, the results of this study can provide a good infrastructure for the next preventive program and have clinical implications for CRC screening.
