914 Dissection-Enabled Scaffold-Assisted Resection (DeSCAR): A Novel Technique for Resection of Residual or Non-Lifting GI Neoplasia of the Colon, Expanded Experience and Follow-Up

INTRODUCTION: Colonic lesions referred for endoscopic mucosal resection (EMR) may not be amenable to conventional snare resection due to previous manipulation or submucosal invasion or because of flat lesions unable to be snared. In 2018, we initially described Dissection-enabled Scaffold Assisted Resection (DeSCAR)—a combination of circumferential endoscopic submucosal dissection (ESD) with EMR—to be safe for the endoscopic resection for...
