Does Inspection During Insertion Improve Adenoma Yields During Colonoscopy?

Completed · Not applicable

Conditions studied: Colorectal Cancer, Colorectal Polyps

In brief

Colonoscopy is not a perfect test. It misses a substantial number of neoplastic lesions and has some risk of missing cancer. Nearly all work on detection during colonoscopy has focused on the withdrawal phase of the examination. This randomized, controlled trial will compare the additional effect on the rate of adenoma detection of mucosal inspection during colonoscope insertion, with inspection during instrument withdrawal, in patients undergoing colonoscopy for colorectal cancer screening or surveillance.
