Safety and efficacy of hot avulsion as an adjunct to endoscopic mucosal resection (with videos)

Excision of all visible neoplastic tissue is the goal of endoscopic mucosal resection (EMR) of colorectal laterally spreading tumors (LSTs). Flat and fibrotic tissue can resist snaring. Ablation of visible polyps is associated with high recurrence rates. Avulsion is a technique to continue resection when snaring fails.
