Colorectal Cancer, Colorectal Polyps
Does Inspection During Insertion Improve Adenoma Yields During Colonoscopy?
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.
