ABSTRACT
The goal of this study was to determine whether high-definition white light endoscopy with random biopsies (HD-WLR) or chromoendoscopy (HDCE) yielded a higher dysplasia detection rate in ulcerative colitis patients. Ulcerative colitis (UC) patients have a 2.4-fold increased future risk of developing colorectal cancer compared to the general population and require careful dysplasia screening modalities. Both HD-WLR and HDCE are regularly used, and recent guidelines do not suggest a preference. UC patients who underwent dysplasia surveillance at our site between January 2019 and 2021 were retrospectively reviewed. We calculated the dysplasia detection rate of both techniques at the first CRC screening colonoscopy. Eighteen dysplastic lesions were detected in total, 3 by HD-WLR and fifteen by HDCE. Dysplasia was detected in 4% (3/75) and 20% (15/75) of UC patients by HD-WLR and HDCE respectively, with significantly fewer biopsies (4.44â

13.0) required using the former. HD-WLR detected 2 polypoid and one non-polypoid lesion, while HDCE detected eleven polypoid and 4 non-polypoid lesions. No invisible dysplasia or colorectal cancer was detected. Screening was performed at 10.8â
