| [ Summary ] | We performed a prospective multicenter randomized controlled trial to compare between panchromoendoscopy and pancolonic narrow band imaging (NBI) observation as tools for surveillance colonoscopy in patients presenting with ulcerative colitis. This Navigator Study revealed that pancolonic NBI observation was not inferior to panchromoendoscopy for the detection of neoplastic lesions. The quality of a surveillance colonoscopy can be improved by the detection of suspected lesions and following characterization, it can help in demarcating a lesion and its depth and establishing the differential diagnoses for ulcerative colitis-associated vs. sporadic neoplasia. The detection rate of pancolonic NBI observation used for surveillance colonoscopy is not inferior to that observed with panchromoendoscopy or that observed in previous reports. | |
