Protection by Endoscopy Against Death From Colorectal Cancer

摘要: Background: Although several clinical and epidemiologic studies suggest that timely diagnostic procedures of the large bowel may reduce mortality from colorectal cancer, evidence for this relationship is primarily circumstantial. Methods: A case-control study was conducted among hospitalized US military veterans to investigate whether were performed in period preceding diagnosis cancer less frequently patients dying than control patients. Data files a total 4411 between 1988 1992 extracted records Department Veterans Affairs, Washington, DC. four living dead without matched by age, sex, race each case patient. The two populations compared conditional logistic regression, calculating odds ratios, their 95% confidence interval. Results: Diagnostic reduced ratio being 0.41 (range, 0.33 0.50) comparison with protective effects proctosigmoidoscopy, colonoscopy, polypectomy lasted 5 years. against death colon, as well rectum. most influence associated removal tissue through biopsy, fulguration, polypectomy. Similar influences found comparing Conclusion: Removal represents effective means cancers bowel. It retains its efficacy over time (Arch Intern Med. 1995;155:1741-1748)
