Guidelines for use of flexible fiberoptic colonoscopy in management of patients with colorectal neoplasia.

Flexible fiberoptic colonoscopy, to have the maximum effect upon the management of patients having, suspected of, or at risk of having colorectal neoplastic disease, must be applied in accordance with substantial guidelines. Schemes for the application of colonoscopy have been designed for the early and accurate diagnosis of benign and malignant polypoid lesions. Colonoscopy has proven effective in confirming radiographic findings and the removal of pre-malignant and superficially malignant lesions. When applied in accordance with appropriate guidelines, flexible fiberoptic colonoscopy should provide not only secure surveillance in those individuals at high risk, but also should reduce appreciably the morbidity and mortality of colorectal neoplasia.
