Abstract
BACKGROUND AND AIMS Residual neoplasia after macroscopically complete EMR of large colon polyps has been reported in 10% to 32% of resections. Often, residual polyps at the site of prior polypectomy are fibrotic and nonlifting, making additional resection challenging. METHODS This document reviews devices and methods for the endoscopic treatment of fibrotic and/or residual polyps. In addition, techniques reported to reduce the incidence of residual neoplasia after endoscopic resection are discussed. RESULTS Descriptions of technologies and available outcomes data are summarized for argon plasma coagulation ablation, snare-tip coagulation, avulsion techniques, grasp-and-snare technique, EndoRotor endoscopic resection system, endoscopic full-thickness resection device, and salvage endoscopic submucosal dissection. CONCLUSIONS Several technologies and techniques discussed in this document may aid in the prevention and/or resection of fibrotic and nonlifting polyps.

Abstract
BACKGROUND & AIMS Endoscopic submucosal dissection (ESD) was developed for en bloc resection of superficial neoplasm of the digestive tract. We evaluated feasibility and safety of ESD, as a salvage therapy of large refractory rectal polyps, in a tertiary care setting. METHODS We prospectively enrolled in the present study and treated by ESD 11 consecutive patients with rectal polyps (median diameter 3.5 cm; range 2-5 cm), who had previously undergone several attempts of endoscopic resection and not suitable for further standard endoscopic treatment. The ESD was carried out with a standard needle knife. Follow up examinations were scheduled at 3, 6, 12 and 24 months. RESULTS We achieved apparently complete resection of polyps in 10/11 patients. In one patient ESD was interrupted and the pathology of the resected fragment showed deep submucosal infiltration; this patient underwent surgery. Deep and lateral margins were shown to be free of neoplasm (radical resection) in six out of 11 patients. However all the 10 patients with apparently complete resection were free of recurrence after a mean follow up of 19.2 months (12-24). A T1 adenocarcinoma was radically resected by ESD, with no recurrence. We recorded 2 cases of subcutaneous emphysema, both treated conservatively. CONCLUSIONS Radical resection is difficult to be achieved by ESD in patients with rectal scar-embedded polyps. Nevertheless ESD may be proposed as a definitive treatment of selected patients with refractory polyps, avoiding surgery in the majority of them.
