    Excerpt

    BACKGROUND:: Although colonoscopy is currently the optimal method for detecting colorectal polyps, some are missed. The Third Eye Retroscope provides an additional retrograde view that may detect polyps behind folds. OBJECTIVE:: To determine whether the addition of the Third Eye Retroscope to colonoscopy improves the adenoma detection rate. DESIGN:: Prospective, multicenter, randomized, controlled trial. SETTING:: Nine European and U.S. centers. PATIENTS:: Of 448 enrolled subjects, 395 had data for 2 procedures. INTERVENTIONS:: Subjects underwent same-day tandem examinations with standard colonoscopy (SC) and Third Eye colonoscopy (TEC). Subjects were randomized to SC followed by TEC or TEC followed by SC. MAIN OUTCOME MEASUREMENTS:: Detection rates for all polyps and adenomas with each method. RESULTS:: In the per-protocol population, 173 subjects underwent SC and then TEC, and TEC yielded 78 additional polyps (48.8%), including 49 adenomas (45.8%). In 176 subjects undergoing TEC and then SC, SC yielded 31 additional polyps (19.0%), including 26 adenomas (22.6%). Net additional detection rates with TEC were 29.8% for polyps and 23.2% for adenomas. The relative risk of missing with SC compared with TEC was 2.56 for polyps (P < .001) and 1.92 for adenomas (P = .029). Mean withdrawal times for SC and TEC were 7.58 and 9.52 minutes, respectively (P < .001). The median difference in withdrawal times was 1 minute (P < .001). The mean total procedure times for SC and TEC were 16.97 and 20.87 minutes, respectively (P < .001). LIMITATIONS:: Despite randomization and a large cohort, there was disparity in polyp prevalence between the 2 groups of subjects. CONCLUSION:: The Third Eye Retroscope increases adenoma detection rate by visualizing areas behind folds. (Clinical trial registration number: NCT01044732.).
