Impact of Sigmoidoscopy and Colonoscopy on Colorectal Cancer Incidence and Mortality: An Evidence-Based Review of Published Prospective and Retrospective Studies
Screening for colorectal cancer (CRC) using sigmoidoscopy or colonoscopy is now common in many developed countries. This concise, evidence-based review looks at the impact of sigmoidoscopy or colonoscopy screening on CRC incidence, CRC mortality and overall mortality.

Mounting evidence shows that colorectal screening reduces cancer incidence and mortality, but scientists still disagree about the best way to look for risky polyps. Clinicians in the US favor colonoscopy, while European health systems rely far more on flexible sigmoidoscopy–a cheaper, less invasive method that can be performed without sedation, but that also reaches only into the distal or “lef...
متن کاملUse of flexible sigmoidoscopy to screen for colorectal cancer in HIV-infected patients 50 years of age and older.
BACKGROUND Although many patients with human immunodeficiency virus (HIV) infection are now living well beyond 50 years of age, there are no data available on colorectal cancer screening in this population. The aim of this study was to determine the utility of screening flexible sigmoidoscopy in patients with HIV. METHODS Consecutive patients at average risk for colorectal cancer who were ref...
متن کاملCost-effectiveness of colonoscopy in screening for colorectal cancer.
BACKGROUND Fecal occult blood testing, flexible sigmoidoscopy, and colonoscopy are used to screen patients for colorectal cancer. OBJECTIVE To compare the cost-effectiveness of fecal occult blood testing, flexible sigmoidoscopy, and colonoscopy. DESIGN The cost-effectiveness of the three screening strategies was compared by using computer models of a Markov process. In the model, a hypothet...
متن کاملA randomized, controlled trial to assess a novel colorectal cancer screening strategy: the conversion strategy--a comparison of sequential sigmoidoscopy and colonoscopy with immediate conversion from sigmoidoscopy to colonoscopy in patients with an abnormal screening sigmoidoscopy.
OBJECTIVE Our study was a randomized, controlled trial to assess a novel strategy that provides comprehensive colorectal cancer screening in a single visit versus traditional sigmoidoscopy and, where appropriate, colonoscopy on a subsequent day. METHODS Consecutive patients referred for screening were randomized to control or so-called "conversion" groups. Patients in the control group were p...
