Position Changes During Colonoscope Withdrawal and Polyp Detection
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.
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Diagnostic
|Official Title:||Position Changes During Colonoscope Withdrawal to Increase Polyp Detection: a Prospective Randomized Trial|
- Polyp detection rate [ Time Frame: 6 minutes ] [ Designated as safety issue: No ]
|Study Start Date:||July 2011|
|Estimated Study Completion Date:||December 2013|
|Primary Completion Date:||July 2012 (Final data collection date for primary outcome measure)|
Placebo Comparator: Control
Subject will undergo standard colonoscopy.
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.
