What is the most appropriate interval for follow-up colonoscopy after a hyperplastic polyp?

The recommended interval for follow-up colonoscopy after the detection of a hyperplastic polyp is typically 10 years. Hyperplastic polyps are generally considered low-risk lesions that do not have significant malignant potential, especially when they are smaller than 1 cm. Therefore, patients with a history of hyperplastic polyps can usually safely undergo surveillance colonoscopy at longer intervals compared to more advanced types of polyps, which may present a higher risk for colorectal cancer.

In clinical practice guidelines, the finding of a hyperplastic polyp, particularly in the context of average-risk screening, often allows for extended screening intervals, as the likelihood of progression from these types of polyps to cancer is very low. This is based on studies that indicate the stability of such polyps over time and the absence of significant findings necessitating more frequent surveillance. Thus, following up in a decade is considered an appropriate and evidence-based approach.
