Whether some colorectal polyps can be resected and discarded without pathologic assessment is the subject of much debate. To examine this issue further, investigators tested whether a strategy based on endoscopic and clinical findings could accurately replicate surveillance recommendations based on pathologic evidence.
Under this strategy, polyps would be submitted for pathology if they were >5 mm in size or diminutive (≤5 mm) but with appearance suggestive of cancer; if ≥3 polyps <10 mm were present; or if 1 or 2 diminutive polyps were present, but the patient had no history of colorectal cancer or adenoma.
