Improvement in the visibility of colorectal polyps by using blue laser imaging

Abstract

Results: The mean visibility scores of the BLI bright mode were significantly higher than those of WL for both experts and nonexperts (experts, 3.10 0.95 vs 2.90 1.09; P Z .00013; nonexperts, 3.04 0.94 vs 2.78 1.03; P! .0001). For all nonexperts, the visibility scores of the BLI bright mode were significantly higher than those of WL; however, these scores were significantly higher in only 2 experts. For experts, the mean visibility scores of the BLI bright mode was significantly higher than those of WL for flat polyps, neoplastic polyps, and polyps located on the left side of the colon and the rectum. Limitations: Small sample size and review of videos. Conclusions: Our study showed that polyps were more easily visible with the BLI bright mode compared with WL.
