Position Changes During Colonoscope Withdrawal and Polyp Detection

September 29, 2014 updated by: University of British Columbia

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.

  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Placebo Comparator: Control
Subject will undergo standard colonoscopy.
Procedure: Standard
Subjects will undergo standard colonoscopy without position changes during scope withdrawal.
Active Comparator: Position change
Subject will under go standard colonoscopy, but also with position changes during colonoscope withdrawal.
Procedure: Position change
Patients will be randomly assigned to two groups: Control group (those who will receive standard colonoscopy without position changes) and Position change group (those who will undergo position changes during colonoscope withdrawal during colonoscopy). Subjects in position change group will be asked to shift into three different positions during colonoscope withdrawal.
