Diminutive colorectal lesions are polyps and flat lesions 1 to 5 mm in size, and small are 6 to 9 mm in size. The best resection method is the cold snare. Cold forceps are acceptable for 1- to 3-mm lesions, but should not be used to piecemeal polyps. Cold snaring has few complications and is more effective than cold forceps for 4- to 5-mm polyps and as effective and more efficient than hot snaring for 6- to 9-mm polyps.
微小的结直肠病变是指大小为1至5毫米的息肉和扁平病变，小病变是指大小为6至9毫米的病变。最佳切除方法是冷圈套器。对于1至3毫米的病变，冷活检钳是可以接受的，但不应将息肉逐块切除。冷圈套切除并发症少，对于4至5毫米的息肉比冷活检钳更有效，对于6至9毫米的息肉与热圈套切除效果相同且效率更高。
