Abstract

Ulcerative colitis (UC), one of the most common forms of chronic inflammatory bowel disease, is characterized by exacerbations and remissions. Even when conventional colonoscopy suggests remission and a normal mucosal finding, microscopic or histological abnormalities may persist, and relapse may be imminent. Confocal microendoscopy allows histological diagnosis during the endoscopic examination. High-resolution video-magnifying colonoscopy with chromoscopy enables the observation of colorectal mucosal pit patterns and prediction of the probability of subsequent disease relapse in patients in remission. Endoscopic ultrasonography provides an immediate and accurate evaluation of the health status of the colonic wall without the need to wait for histological results and provides an indication of the efficacy of treatment. These novel endoscopic techniques are useful for the evaluation of disease activity and the efficacy of treatment in patients with UC and the prediction of relapse.
