Repeat forward\u2010view (RF) examination of the right\u2010sided colon has been suggested to increase the adenoma detection rate (ADR). However, studies investigating the efficacy of RF examination are lacking. Thus, the aim of this study was to determine whether RF examination in the right\u2010sided colon enhances right\u2010sided ADR.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We performed a prospective, randomized controlled trial, including asymptomatic subjects who underwent screening colonoscopy. Subjects were randomized to the RF group, in which the right\u2010sided colon was examined twice in the forward view, or to the standard forward\u2010view (SF) group, in which the right\u2010sided colon was examined once in the forward view. The primary outcome was the right\u2010sided ADR on RF examination of the right\u2010sided colon.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 640 subjects completed the study protocol (RF group, <jats:italic>n<\/jats:italic>\u00a0=\u00a0320; SF group, <jats:italic>n<\/jats:italic>\u00a0=\u00a0320). The right\u2010sided ADR in the RF group was significantly higher than that in the SF group (17.5% <jats:italic>vs<\/jats:italic> 11.9%, respectively; <jats:italic>P<\/jats:italic>\u00a0=\u00a00.044). In the RF group, an additional 31 adenomas were found, resulting in an increased detection rate of adenomas of 38.3% compared with the first forward view. The ADR of the whole colon was similar between the groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>In our prospective randomized controlled trial, RF examination of the right\u2010sided colon, which can be easily performed in clinical practice, was associated with an increased rate of detection of right\u2010sided
