Sa1436 G-EYE Advanced Colonoscopy for Increased Polyp Detection Rate- Randomized Tandem Study With Different Endoscopist -

New endoscopes and add-on devices to improve colonoscopy performance

“…With the balloon inflated during withdrawal, colonic folds and flexures are mechanically straightened revealing potential suspicious lesions located in their proximal aspect[ 62 ]. Two randomized tandem studies[ 63 , 64 ] evaluated G-EYE’s lesions miss rates compared to SFV. Both studies examined individuals undergoing colonoscopy for various reasons.…”

“…Both studies examined individuals undergoing colonoscopy for various reasons. Halpern et al[ 63 ] demonstrated a significant lower adenoma miss rate for G-EYE (7.5% vs 44.7%, P = 0.0002), while Rey et al[ 64 ] showed a lower polyp miss rate in favor of the G-EYE (7% vs 41%). In terms of ADR and adenomas per colonoscopy this device has been evaluated in three randomized parallel design studies[ 65 - 67 ].…”

UEG Week 2014 highlights: putting endoscopy into perspective

“…A significant increase in adenoma detection rate was reported with the new system (35.4 % vs. 23.5 %) as well as an increased proportion of adenomas per patient (0.63 vs. 0.36). Another report from Germany, comparing G-EYE with conventional colonoscopy and including 45 patients, reported an increase in polyp detection rate in favor of G-EYE (with a 100 % additional detection of adenomas) and a significant reduction in polyp miss rate (18.6 % for G-EYE vs. 48 % for conventional colonoscopy) [36]. One of the study's most interesting features is that although the design was a back-to-back study, the endoscopists changed after each withdrawal in order to reduce bias, which has been a criticism of previous tandem studies [37].…”
