Position Changes During Colonoscope Withdrawal and Polyp Detection

Position Changes During Colonoscope Withdrawal to Increase Polyp Detection: a Prospective Randomized Trial

The purpose of this study is to determine whether position changes during colonoscope withdrawal affects polyp detection rate. We hypothesize that positions change during scope withdrawal will increase polyp detection rate.
