A patient is diagnosed with Serrated Polyposis Syndrome (SPS) based on specific criteria related to the number, size, and location of serrated polyps, and family history.
SPS Diagnostic Criteria
The diagnostic criteria for SPS, according to the provided reference, include the following:
- Criterion 1: At least five serrated polyps proximal to the sigmoid colon, with two or more being greater than 10 mm in diameter.
- Criterion 2: Any number of serrated polyps occurring proximal to the sigmoid colon in an individual who has a first-degree relative with SPS.
In simpler terms, a diagnosis of SPS is made if either of these conditions are met:
-
Multiple Large Polyps: The patient has at least five serrated polyps located before the sigmoid colon, and at least two of those polyps are larger than 10 millimeters in diameter.
-
Family History and Polyps: The patient has any number of serrated polyps before the sigmoid colon and also has a parent, sibling, or child diagnosed with SPS.
