Shan K, Lu H, Zhang Z, et al. - Since colorectal cancer on the right side of the colon has been suggested to be harder to detect by colonoscopy, researchers conducted this single-centre randomized controlled trial to determine whether a second forward-view examination of the right side of the colon could increase the adenoma detection rate (ADR) and/or polyp detection rate (PDR). Patients undergoing colonoscopy were recruited and randomly assigned to one of two groups: the second forward-view examination (SFE) group, which examined the right side of the colon twice, or the traditional colonoscopy (TC) group, which performed the colonoscopy in a standard manner. In total, 392 patients were involved in the study (SFE group 197 vs TC group 195). A second forward-view examination could modestly increase the ADR and PDR of the right colon during unsedated colonoscopies, according to this prospective controlled study. This simple, safe, and time-saving technique could be used for routine unsedated colonoscopy.
