Abstract

There are some surgical indications for early colorectal neoplasms in which lymphadenectomy is not necessary. Staging techniques such as EUS are insufficiently reliable to distinguish subtle submucosal invasion in superficial colorectal neoplasms. There is room for a combined diagnostic and potentially therapeutic endoscopic intervention in these superficial lesions, providing optimal histological T staging is obtained. Endoscopic submucosal dissection (ESD) may be used in this setting.
