In a Boston Globe news report, Dr. Saltzman said colonoscopy is a better way to screen for colon cancer than sigmoidoscopy because the latter modality has several disadvantages, including a limited view of the colon. While sigmoidoscopy only examines the bottom third of a patient’s colon, colonoscopy is the only modality that screens the entire colon.
Dr. Abramson disagreed, saying there is a need for more “well-performed scientific studies” that prove colonoscopy is the better screening modality. Additionally, sigmoidoscopy does not require laxatives, which can be uncomfortable for patients, and amounts to only one-tenth of the cost of a colonoscopy. Because sigmoidoscopy doesn’t require anesthesia, there is also a lowered risk of perforation of the colon, Dr. Abramson said.
