The evolution of more sophisticated diagnostic imaging (eg, angiography, bleeding scanning, flexible fiberoptic colonoscopy) offers the promise of precise localization of the bleeding site. These advances also provide nonoperative and less invasive control of bleeding using angiographic techniques or colonoscopy. Pharmacologic discoveries are also improving patient care and outcome. Therefore, the therapeutic armamentaria have expanded greatly in the last several decades.
