Snare type appears to be an important determinant of completeness of excision when removing small polyps by the cold snare technique.

There is strong evidence that chromoscopy enhances the detection of neoplasia in the colon and rectum. People with neoplastic polyps, particularly those with multiple polyps, are at increased risk of developing colorectal cancer. Such lesions, which presumably would be missed with conventional colonoscopy, could contribute to the interval cancer numbers on any surveillance programme.

In this study both polypectomy techniques were found to be safe and highly effective, but further large multicenter trials are required.Clinical trial registration at www.clinicaltrials.gov: NCT02208401.
