Polyps Clinical Trial
Official title:
Evaluation of the Effect of Position Change During the Withdrawal Phase of Colonoscopy on Adenoma Detection Rate
The hypothesis to be tested is that position changes during the withdrawal phase of
colonoscopy leads to a higher adenoma (polyp) detection rate because of better distension of
the colon. Since adenomas are precancerous lesions the enhanced adenoma detection will
increase the success of colorectal cancer screening programmes. This study will provide
evidence for the value of position changes and encourage endoscopist to adopt position
change as a routine in their practice.
May 2007: protocol amendment to include additional prospective analysis using High
Definition TV (HDTV).
