- Abstract
- Background and Aim: There is controversy about the surveillance interval after colonoscopy when 5-10 adenomas have been found on index colonoscopy. This study aimed to investigate the risk of colorectal neoplasm (CRN) according to the number of adenomas at index colonoscopy. Methods: A retrospective, multicenter study was conducted at 10 university hospitals in Korea. We included 1394 patients with >= 3 adenomas at index colonoscopy. The risk of advanced CRN was compared according to the number of adenomas (intermediate risk group, 3-4 small adenomas or at least one >= 10 mm, and high risk group, >= 5 small adenomas or >= 3 at least one >= 10 mm). Results: Overall, 164 (11.8%) developed an advanced CRN after a mean of 4.0 years from baseline colonoscopy. The 3-year and 5-year risk of advanced CRN was 2.1% (95% CI 2.09-2.11) and 14.4% (95% CI 14.36-14.44) in intermediate risk group and 3.2% (95% CI 3.19-3.21) and 23.3% (95% CI 19.15-19.25) in high risk group (P = 0.01). Having = 5 adenomas (OR = 1.57, 95% CI 1.11-2.23, P = 0.01) detected at index colonoscopy was a significant risk factor for developing advanced CRN. Conclusions: Although risk of advanced CRN in patients with 5-10 adenomas was significantly higher than that in patients with 3-4 adenomas, the cumulative risk at 3 years was low at 3.2%. Thus, we suggest that a 3-year surveillance interval might be appropriate for the patients with 5-10 adenomas, and further prospective studies are needed to investigate whether more intensive surveillance is needed in this group.
