Aims Colonoscopy is considered the gold standard for colorectal cancer screening but lesions can be missed, resulting in interval cancers in a significant number of patients. Polyps hidden behind haustral folds or in tight flexures are particularly difficult to visualize with current forward-viewing instruments. This prospective study evaluated lesion detection rate and performance of a novel colonoscope with 230-degree (partially retrograde) extra-wide field of view compared to the standard 170-degree colonoscope in a colon model.
