How we resect colorectal polyps <20 mm in size

We review our approach to resection of colorectal polyps <20 mm in size. Careful inspection of all lesions is appropriate to assess the type of lesion (adenoma vs serrated) and evaluate the risk of cancer, which is highly associated with lesion size. Polyp resection is in the midst of a "cold revolution," particularly for lesions <10 mm in size, but also for some larger lesions. Cold forceps are sometimes appropriate for 1- to 2-mm lesions that can be engulfed in one bite, but we use cold snaring for almost the entire set of lesions <10 mm.
