Yu Bai et al. Impact of preprocedure simethicone on adenoma detection rate during colonoscopy: a multicenter, endoscopist-blinded randomized controlled trial

This randomized controlled trial involving 583 Chinese patients examined whether adding oral simethicone to bowel preparation with polyethylene glycol (PEG) could improve the adenoma detection rate. When compared with PEG alone, PEG plus simethicone improved the adenoma detection rate (21 % vs. 14 %) and mean number of adenomas detected (2.2 vs. 1.6). The benefit was maintained after adjusting for bowel preparation quality, which was better in the intervention group.
