The overall ADR in the right colon was significantly higher in the WLI\u2010NBI group than that in the repeat\u2010WLI group (27.1% vs. 17.9%; <jats:italic>p<\/jats:italic>\u2009=\u20090.022). The number of adenomas per colonoscopy in the right colon was also significantly higher in the WLI\u2010NBI group than in the repeat\u2010WLI group (mean number of adenomas, 0.36 vs. 0.24; <jats:italic>p<\/jats:italic>\u2009=\u20090.042). However, there were no significant differences in the detection rates of advanced adenomas and sessile serrated lesions between the WLI\u2010NBI and repeat\u2010WLI groups (advanced adenoma, 4.7% vs. 2.9%; sessile serrated lesion, 2.5% vs. 3.3%).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>A second forward examination of the right colon using NBI increased ADRs in
