Third Eye Retroscope Randomized Clinical Evaluation (The "TERRACE" Study)

Avantis Medical Systems·interventional·Posted Jan 8, 2010·Updated Jul 25, 2017

In Brief

A clinical study evaluating Third Eye Retroscope for Colorectal Neoplasms. Completed, enrolled 448 participants across 9 sites in 5 countries.

Detailed Summary

The Third Eye® Retroscope® is a device that can be inserted through the instrument channel of a standard colonoscope to provide an additional, retrograde (or backward) view that reveals areas behind folds and flexures in the colon, and might detect additional polyps that cannot be seen with the colonoscope alone. Patients who participate as subjects in the study will undergo two complete colonoscopy procedures, a standard colonoscopy and a colonoscopy in which a Third Eye Retroscope is used along with the same colonoscope. Half of the patients will have the standard colonoscopy first followed by the Third Eye colonoscopy, and the other half will have the Third Eye procedure first. Results from the two groups will be analyzed and compared to determine the effectiveness of the Third Eye Retroscope for detecting additional adenomas and other polyps compared with the standard colonoscope alone.
