Removing a polyp during colonoscopy is usually done with a snare polypectomy. In this approach, a thin wire loop (the snare) is placed around the base of the polyp and tightened, then the polyp is cut off, often with a small amount of electric current to cauterize the tissue and reduce bleeding. This method is the go-to technique for many polyps because it can remove the lesion cleanly in one piece and provides tissue for pathology.

Endoscopic Mucosal Resection is typically used for larger or more complex lesions where a bigger piece of tissue needs to be removed and may involve lifting the lesion with injection and then snaring. Biopsy, on the other hand, pulls tissue for sampling and does not usually remove the entire polyp. Cold snare polypectomy is a variation that removes polyps with a non-energized snare, mainly for very small polyps, but the standard approach described here for removing a polyp is snare polypectomy with cautery.
