Abstract:
New diagnostic technologies can visualize colon polyps, but not remove them. There is clear consensus that polyps 10 mm or larger need to be removed. There is still controversy surrounding the appropriate reporting and management of small 1 to 5 mm and 6 to 9 mm polyps. The author recommends that patients whose largest polyp is 6 mm or larger should be offered colonoscopy. If the largest polyp is less than 6 mm in size, and imaged with high reliability, the author recommends reporting the finding, and individualizing the decision to pursue colonoscopy versus repeat imaging.
