| [ Summary ] | The clinical utility of magnifying colonoscopy in diagnosing colorectal tumors, including those with pit patterns and the use of Narrow Band Imaging diagnosis in relation to endoscopic treatment is reviewed. In order to select an adequate therapeutic method for en bloc endoscopic mucosal resection (EMR), piecemeal EMR, endoscopic submucosal dissection (ESD) and surgical resection for treatment of colorectal tumors, it is important to determine the characteristics of lesions, such as adenoma or carcinoma. Focal carcinoma in adenoma vs. de novo carcinoma and tumor invasion depth must also be determined prior to treatment. Magnifying colonoscopy, including pit pattern diagnosis and Narrow Band Imaging, is essential for precise diagnosis. | |
