How often should patients with sessile serrated polyposis syndrome undergo surveillance colonoscopy?

1. 1 year

2. 3 years

3. 5 years

4. 10 years

The correct answer is: 1 year

Patients with sessile serrated polyposis syndrome are at an increased risk of colorectal cancer due to the presence of serrated polyps, which can demonstrate a dysplastic process that may progress to malignancy. Surveillance colonoscopy is a critical part of the management strategy for these patients to monitor for the development of new polyps, as well as changes in existing polyps. The recommendation for surveillance colonoscopy in individuals with sessile serrated polyposis syndrome is typically every 1 year. This frequency allows for early detection and removal of any polyps, which is essential in preventing colorectal cancer. Early intervention can significantly reduce the risk associated with this syndrome. Regular surveillance at this interval ensures that any changes in polyp number, size, or pathology can be promptly addressed, maintaining a proactive approach to patient care. This rigorous approach is based on the understanding of the underlying pathology of sessile serrated lesions and their potential for progression, thus emphasizing the importance of closer follow-up compared to other conditions that may have longer intervals recommended for surveillance.
