State of Art Update: Detection and Classification of Early Colonic Neoplasia
Journal Title: Archives of Clinical Gastroenterology - Year 2017, Vol 3, Issue 1
Abstract
Colonoscopy has been shown to be effective in the detection and removal of precancerous lesions and early cancers, and as a result, colorectal screening programs are in preparation, or in place throughout the world. Screening efforts are reducing the incidence of colorectal cancer (CRC) and allow diagnosis CRCs at an earlier stage. It is increasingly evident that colonoscopic polypectomy including endoscopic mucosal resection and submucosal dissection has become a means of cancer prevention with evidence of reduced predicted incidence and mortality of colorectal malignancies. However, the risk of interval CRC relates to the skill of the performing colonoscopist, rather than any patient or polyp characteristic. Every endoscopist needs to actively look for proximal and flat or depressed lesions. For the general endoscopist, this means the ability to find and accurately assess a lesion is vital. In addition, advancing endotherapeutics means more lesions are potentially removable, and so endoscopists must be able to describe lesions in a standard fashion. This review deals with the current means of describing lesion morphology and surface characteristics, together with the significance of these. We also discuss the developing adjuncts to endoscopic imaging.
