NCT03814369

Brief Summary

Colonoscopy screening is proven to reduce mortality rates for colorectal cancer, which relies on early detection and removal of colonic polyps. AmplifEYE is a FDA-approved device with a row of flexible detection arms attached to the tip of colonoscope which can separate colonic folds during scope withdrawal and is believed to improve polyp detection. Real-life clinical data on this relatively new device is lacking and this study aims to compare the adenoma and polyp detection rates in AmplifEYE-assisted colonoscopy versus standard colonoscopy.
