Assessment of Colorectal Lesions Using Magnifying Colonoscopy and Mucosal Dye Spraying: Can Significant Lesions Be Distinguished?

Abstract

The combination of magnifying colonoscopy and dye spraying is helpful in determining the nature of colonic lesions as non-neoplastic, adenomas, or invasive carcinomas. Therefore it may be possible to determine, at the time of colonoscopy, which lesions require no treatment, which can be removed endoscopically, and which should be removed by surgery.
