Abstract

Background & Aims Guidelines recommend a 10-year interval between screening colonoscopies with negative results for average-risk individuals. However, many patients are examined at shorter intervals. We investigated outcomes of individuals with no polyps who had repeat colonoscopy in 9 mm - a proportion similar to the prevalence in the average-risk screening population. Reasons that examinations were repeated within 1-5 years included average-risk screening (15.7%), family history of colon polyps or cancer (30.1%), bleeding (31.2%), gastrointestinal symptoms (11.8%), or a positive result from a fecal blood test (5.5%). If the baseline examination was adequate, the incidence of large polyps within 1-5 years after baseline colonoscopy was 3.1% (95% confidence interval: 2.7-3.5) and within years 5-10 years was 3.7% (95% confidence interval: 3.3-4.1). Conclusions Repeat colonoscopies within 10 years are of little benefit to patients who had adequate examinations and were found to have no polyps. Repeat colonoscopies are beneficial to patients when the baseline examination was compromised.
