Researchers say postpolypectomy colonoscopy intervals can be extended beyond the traditional five-year mark for patients with nonadvanced adenomas, according to a study published in the Journal of Clinical Gastroenterology.
For the study, researchers identified 399 patients with and without adenomas who returned for a follow-up colonoscopy 5-10 years later. Results showed patients with nonadvanced adenomas had a comparable risk of advanced adenoma at their follow-up colonoscopy at five years compared to 6-10 years (5 percent and 6.2 percent, respectively).
However, the risk of advanced adenoma at five years and 6-10 years in patients with a negative index colonoscopy was 7 percent and 3.6 percent, respectively. Researchers concluded a rescreening interval of 5-10 years for this patient population is appropriate. Additionally, patients with an advanced adenoma at index colonoscopy had the highest rate of advanced adenoma detection at the five-year mark, suggesting this patient population should have a repeat colonoscopy before the five-year mark.
