Bubbles are frequently encountered during colonoscopy and can interfere with adequate visualization. Through-the-scope simethicone is often used to eliminate the bubbles, but this practice has raised concerns about transmission of infections via contaminated endoscopes.
In a randomized, controlled trial, investigators compared colonoscopy quality metrics and the need to use through-the-scope simethicone in 268 patients who received a standard split polyethylene glycol prep with or without oral simethicone.
