Comparing adenoma and polyp miss rates for total underwater colonoscopy versus standard CO2: a randomized controlled trial using a tandem colonoscopy approach

Although water exchange may improve adenoma detection when compared to CO2, it is unclear whether water is a better medium to fill the lumen during withdrawal and visualize the mucosa. Total underwater (TUC) involves the use of water exchange with the air valve off during insertion followed by the inspection of the mucosa under water. Our goal was to use a tandem colonoscopy design to compare miss rates for TUC to standard CO2 for polyps and adenomas.
