 The number of ulcerative colitis(UC)and UC-associated neoplasia(UCAN)patients is increasing, and sporadic neoplasia(SN)can develop within the UC-affected mucosa. Even with precise histologic and immunohistochemical analyses, UCAN and SN are difficult to distinguish. Moreover, chromoendoscopy and magnifying endoscopy with narrow-band imaging can detect UCAN, but it is difficult to determine the extent of invasion depth. Several studies have reported the safety and feasibility of endoscopic resection(ER)for UCAN and SN. Although ER can control well-verified neoplastic lesions, long-term outcome of the procedure is a future challenge.
