Advances in the colonoscopic imaging and endoluminal treatment of early colorectal cancer

In the 40 years since its introduction, colonoscopy has revolutionized the detection of colorectal cancer and its precursors. Recent advances in colonoscopic technique have had an important effect on histopathology, (e.g. type of colorectal specimen derived, new interpretative information produced by endoscopists). The authors are endoscopists who use these new techniques to provide histopathologists with relevant information: the Paris classification of endoscopically visualised lesions, the Kudos classification of pit pattern, the technique of endoscopic mucosal resection, and the management implications of the different classifications.
