Widespread use of colonoscopy has achieved a modicum of success, as evidenced by a slight decrease in CRC rates. However, a recent National Institutes of Health consensus panel noted that screening rates are still suboptimal, and thus colorectal malignant neoplasms remain the second leading cause of cancer deaths.1 Moreover, performing colonoscopy on the entire average-risk population (approximately 100 million Americans 50 years or older) is remarkably inefficient, with a low yield of clinically significant neoplasia (approximately 5%-6%).2 Thus, from a cancer prevention perspective, most screening colonoscopies are unproductive.
