Comparison of adenoma detection and miss rates between a novel balloon colonoscope and standard colonoscopy: a randomized tandem study.

Background And Study Aims: Although colonoscopy is the "gold standard" for colorectal cancer screening, a significant number of adenomas are still missed during standard colonoscopy, often because they are hidden behind colonic folds and flexures. The aim of this study was to assess the ability of a novel balloon colonoscope (G-EYE endoscope; Smart Medical Systems, Ra'anana, Israel) to increase adenoma detection and reduce the miss rate compared with standard colonoscopy.

Patients And Methods: This was a multicenter, randomized, prospective, controlled study in patients (age ≥ 40 years) undergoing colonoscopy for screening or diagnostic work-up (including surveillance).
