Possible Ca: Most polyps of the colon are pedunculated and if there are changes, they are in the apex of the polyp and rarely reach the stalk early on. The sessile or flat polyp is difficult to remove since there is no defined base and the lesion may have invaded mucosa requiring local resection after marking the polyp with dye. The surgeon may want to surgically remove the polyp at that time.

GA: Because if they cannot remove the polyp on the second CSPY attempt, they will immediately proceed with removing the polyp with a surgical procedure to open the colon directly.
