COmparison of White Light and Linked COlor Imaging for Detection of RIght COlon Polyps: A Multi Center Prospective Randomized Tandem Colonoscopy Study

All patients consecutively admitted for routine colonoscopy will be included in this prospective randomized crossover study. After randomization, a first exploration of the right colon will be performed in linked color imaging (LCI) or white light imaging (WLI) depending of the randomization. Every polyp will be resected as soon it will be detected. After this first examination, colon will be explored a second time with a light system different from the one used for the first exploration. If a polyp will be detected during the second exploration, it will be counted as a polyp missed by the first exploration method.
