Trial Outcomes & Findings for Efficacy of the Third Eye Retroscope Auxiliary Imaging System (NCT NCT00657371)

NCT ID: NCT00657371

Last Updated: 2013-12-09

Results Overview

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.

13.2 percent of polyps

PRIMARY outcome

Timeframe: Total 30 minutes procedure time with TER use.

Population: Those polyps reported for Third Eye Retroscope were additional, located behind folds and then found with the colonscope only because they were first detected with the Third Eye Retroscope.

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.

SECONDARY outcome

Timeframe: 2 year study period to collect colonoscopy exam results

Colonoscope and TER use where during TER withdrawal forward and retrograde video images observed simultaneously on a wide-screen monitor for purpose of detecting polyps. Colonoscopy procedures completed in approximately 30 minutes total.
