Accuracy of the newly introduced FUSE-system for assessment of disease activity in inflammatory bowel diseases (IBD) compared to high-definition endoscopy

Introduction: In 2013, full-spectrum-endoscopy (FUSE) was introduced as a novel colonoscopy platform. In contrast to other endoscopy systems illumination is achieved by LEDs and not by a xenon light source. In addition, the FUSE-system does not provide high-definition imaging yet. In patients with IBD, precise assessment of disease activity (i.e. mucosal healing) is of paramount importance to predict disease outcome and to guide therapy. Aims: To determine whether FUSE has the potential to assess disease activity in patients with IBD in comparison to a matched cohort of patients undergoing high-definition white-…
