Devices to improve colon polyp detection.

摘要

To improve polyp detection rates, various devices and methods have been used.6'7 Nonendoscopic methods such as CT colonography and mucosal enhancement techniques including chromoendoscopy and electronic mucosal enhancement (eg, narrow-band imaging and multi-band imaging) have recently been reviewed.8"10 This review describes endoscopic technologies designed to improve colon polyp detection by increasing mucosal surface area inspection, including wide-angle lens and cap-fitted colonoscopy, and a through-the-scope retrograde viewing device.
