    Author: Cannon-Albright LA, Bishop DT, Samowitz W, DiSario JA, Lee R, Burt RW.
    Journal: Am J Gastroenterol; 1994 Jun; 89(6):827-31. PubMed ID: 8198089.
    Abstract:
    OBJECTIVES: To provide a proctosigmoidoscopic review of a very large set of unselected control subjects, providing an unbiased view of colonic polyps in the general population. METHODS: Sigmoidoscopic data from 406 sequentially recruited subjects were analyzed. Participation rates were over 85%, and subjects were thus free of the usual selection bias. RESULTS: Thirty-eight percent of screened individuals were found to have distal colonic polyps. Adenomas were found in 12%, and hyperplastic polyps were found in 30% of screened individuals. Adenomas were more prevalent in males and in older individuals. Hyperplastic prevalence did not differ significantly by gender or age. Synchronous adenomatous and hyperplastic polyps occurred in 3% of screened individuals, but these lesions were not associated. CONCLUSIONS: Distal colonic adenomatous and hyperplastic polyps are very common in the general population and are not associated. The high frequency of these polyps raises questions about the feasibility of biopsy for all polyps, and suggests that further study is needed to determine the appropriate indications for subsequent colonoscopy.
