20 A study that looked at narrow-band imaging (NBI; Olympus, Tokyo, Japan) for serrated polyp detection suggested a statistical trend toward improved detection with a mean number of serrated lesions proximal to the sigmoid of 0.51 with NBI versus 0.39 for white light (p=0.085). 21 A subsequent meta-analysis of NBI for detection of non-adenomatous (serrated) lesions suggested significantly improved detection with either first or s
