We present an endoscopic submucosal dissection (ESD) of a 50 mm sessile polyp, Paris Is, 2 cm from the anal margin.

It was used the ERBE VIO3 electrosurgery unit and hybrid-knife T. The procedure begun with the injection of glycerol, indigo carmine and adrenalin. Subsequently, it was made an incision on the mucosa and then performed the submucosal dissection. Pathology confirmed clear vertical and lateral margins.

The narrow lumen, the risk of hemorrhage and nerve fiber injury are some of the challenges when performing ESD near the dentate line. Nonetheless, ESD is safe and effective treating large lesions involving the dentate line.
