Comparison of Adenoma Detection Miss Rates at Colonoscopy Associated With Different Withdrawal Times
Not Recruiting
Trial ID: NCT01802008
Purpose
The objective of this study is to determine the optimal withdrawal time for colonoscopy. A
6-minute withdrawal time is currently the standard of care but has only been evaluated in an
observational fashion. The investigators believe that this should be validated in a
standardized fashion. If the benefits of a 6 minute withdrawal are proven in this study (ie a
low polyp/adenoma miss rate and a high polyp/adenoma detection rate), then this will support
widespread adoption of a 6 minute withdrawal as the standard of care. This in turn may
decrease the occurence of 'interval colon cancers', which are early colon cancers arising in
subjects despite their having undergone colonoscopy. Our hypothesis is that the polyp/adenoma
detection rate will be unacceptably low and the polyp/adenoma miss rate will be unacceptably
high in the 3-minute withdrawal group when compared to the 6-minute withdrawal group.
