N2 - Purpose: The aim of this study was to determine the diagnostic yield of colonoscopy based on clinical indications. Methods: A retrospective chart review was done 872 patients undergoing initial colonoscopy from 7/92-7/95 1995.Mean age was 66.1 years (range 24-99 years). The indications and diagnostic outcome of each procedure was recorded. The clinical predictors of colon carcinoma and colon polyps were defined through univariate and multivariate analysis.

Conclusion: Age, non bleeding abdominal symptoms, and microcytic anemia are independent predictors of colon cancer. This strong correlation between non bleeding abdominal symptoms (i.e. abdominal pain, altered bowel habits) and colon cancer may warrant early colonoscopy for persistent symptoms. Age, history of polyps, melena and non- iron deficiency anemia are independent predictors of presence of polyps.
