Abstract
Although colonoscopy is effective at detecting and removing polyps, which can prevent colorectal cancer (CCR), there is room for improvement. Accurate characterization is necessary to predict histology and to select the most appropriate treatment method; these range from cold-snare polypectomy to surgery through mucosal resection techniques or submucosal dissection. Improvements in CCD captors, optical and numerical zoom functions of colonoscopes, together with virtual chromoendoscopy, can enhance analysis of morphology, pit pattern, and vascular pattern. However, polyp size measurement is problematic, despite it being the basis of all recommendations on polyp resection and monitoring [1] [2] [3].
