EFFICACY OF ESD IN LESIONS LOCATED IN DENTATE LINE. A PROSPECTIVE MULTICENTRIC COMPARATIVE STUDY

However, those which involve the dentate line (DL) up to 1 cm, have been traditional treated by transanal endoscopic microsurgery (TEM). Poor manoeuvrability and the presumable risk of bleeding might become ESD more difficult and unfeasible. Therefore, the lack of prospective comparative studies of ESD with this indication, makes it...
