Study Summary
The purpose of this study is to demonstrate efficacy of the Avantis Third Eye Retroscope auxiliary imaging system. The primary objective of this study is to assess the degree to which incorporating the Third Eye Retroscope auxiliary imaging system in a screening colonoscopy setting results in the detection of additional polyps. Specifically, the primary goals are to estimate (1) the proportion of polyps detected under this protocol that would have been missed without the Third Eye Retroscope, and (2) the proportion of patients found under this protocol to have polyps who would have incorrectly been classified as polyp-free had the Third Eye Retroscope not been used.
Primary Outcome
After cecal intubation, the disposable TER was inserted through the instrument channel of the colonoscope. During withdrawal, the forward and retrograde video images were observed simultaneously on a wide-screen monitor. A 2 year study period was used to collect colonoscopy exam results.
