About

We plan to conduct a randomized trial of tandem colonoscopies comparing water infusion and air insufflation for inspection of mucosa on withdrawal. In one randomized group, water infusion will be employed as the first method for mucosal inspection while in a second group, CO2 insufflation will be used first. This study will be different than usual care since the participants will receive two successive or tandem colonoscopies versus one
