A Prospective, Single Blinded Study for Predicting Colon Polyp Histology With Narrow Band Imaging (NBI)

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.
Verified February 2009 by Midwest Biomedical Research Foundation.

The investigators hypothesize that NBI will have a high accuracy in predicting polyp histology real time during a colonoscopy by visualization of the surface mucosal and vascular patterns. Aim#1: To determine the sensitivity, specificity and accuracy of NBI and standard white light colonoscopy for predicting polyp histology by evaluating the surface mucosal and vascular patterns during colonoscopy. Aim#2: To determine the inter-observer agreement between investigators for the recognition of various polyp patterns.
