Study Summary
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
Primary Outcome
Adenoma-level miss rates will be calculated as the number of additional adenomas detected during the second examination divided by the total number of adenomas detected during both examinations
Interventions
- PROCEDURE Water Infusion first
- PROCEDURE CO2 Insufflation First
