Dissection-enabled scaffold-assisted resection (DeSCAR): a novel technique for resection of residual or non-lifting GI neoplasia of the colon (with video)

Due to previous manipulation or submucosal invasion, GI lesions referred for endoscopic mucosal resection (EMR) frequently have flat areas of visible tissue that cannot be snared. Current methods for treating residual tissue may lead to incomplete eradication or not allow complete tissue sampling for histologic evaluation. Our aim is to describe dissection-enabled scaffold-assisted resection (DeSCAR), a new technique combining circumferential ESD with EMR for removal of superficial non-lifting or residual "islands" with suspected submucosal involvement/fibrosis.
