Official title
Detection and Classification of Colon Polyps: A Comparison of High Definition White Light and Narrow Band Imaging (Endoscopic Trimodal Imaging; ETMI)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Colon cancer is the third most common cancer in western society. To prevent colon cancer it is recommended for people to undergo a screening colonoscopy at the age of fifty. The purpose of the colonoscopy is to remove polyps, since some of these lesions are precancerous. Precancerous polyps are called adenomas. This method of prevention is effective, but the standard colonoscopy currently used does not detect all polyps. Studies have reported a polyp miss rate of about 24%. Furthermore, we are unable to distinguish precancerous polyps from benign polyps, also known as hyperplastic polyps, with standard colonoscopy. This results in all polyps being removed at time of colonoscopy, even the benign polyps. To help improve the detection of colon polyps new endoscopic technologies have been developed. These technologies include high definition white light (HDWL)and high definition narrow band imaging (HDNBI). HDWL improves the overall resolution of the images seen during colonoscopy. HDNBI can help us better classify polyps by enhancing their tissue appearance as well as seeing small blood vessels and capillaries. The goal of this study to determine if HDNBI imaging shows an increased polyp detection rate when compared to the current standard colonoscopy. In addition to develop a classification system to help better differentiate between precancerous polyps and their benign counterparts using HDWL and HDNBI.
