The advantages of colonoscopy include the following: (1) A bleeding lesion is localized in about 50%-70% of patients; (2) definitive treatment, such as thermoregulation, epinephrine injection therapy, clip application, or laser photocoagulation, is possible during the procedure; (3) massively bleeding lesions that have stopped hemorrhaging are identified more often with colonoscopy than with angiography.
