Sessile serrated adenomas are characterized by their flat shape and the presence of a yellow mucus cap overlying the lesion. These morphological features may account for their diagnostic difficulty during colonoscopy. Missed proximal sessile serrated adenomas are regarded as an important cause for interval cancers in the right colon and emphasize the importance of developing quality measures intended to enhance their detection. There is only one single-center retrospective cohort study on the impact of carbon dioxide insufflation on the detection of serrated polyps during colonoscopy. The investigators designed a randomized, controlled trial to compare the effect of carbon dioxide insufflation vs. room air insufflation on serrated polyp detection rate.
