Yield of High-Grade Dysplasia Based on Polyp Size Detected at Colonoscopy: A Series of 2295 Examinations Following a Positive Fecal Occult Blood Test in a Population-Based Study

Abstract

Because of the high rate of high-grade dysplasia among small adenomas, our results reinforce the need to remove all small adenomas detected at colonoscopy. Furthermore, the results suggest that opting for CT colonography surveillance instead of colonoscopic removal among subjects with one or 2 small polyps revealed by CT colonography would have led to missed high-grade dysplasia in 12.4% of them.
