With high definition endoscopes, narrow band imaging (NBI) and improved bowel preparation, adenoma detection rates and lesion characterisation at the time of colonoscopy have improved. Endoscopists are better equipped to not only detect polyps but predict histology using validated criteria such as the Paris (morphology) and Kudo / NICE (NBI International Colorectal Endoscopic) classifications (pit pattern). Histology of resected polyps is a major determinant of surveillance intervals. However, it is costly and not available to patients at the time of their colonoscopy. We hypothesise that in patients undergoing colonoscopy and polypectomy by an experienced “high detector” colonoscopist, that formal polyp histology seldom changes the surveillance interval (determined by the Australian surveillance guidelines) predicted at the time of colonoscopy, when optimal split preparations and enhanced imaging with application of the classification systems above are used.
