EMR with an over-the-scope clip for superficial nonampullary duodenal epithelial tumor with fibrosis Tomoaki Tashima, MD, Kouichi Nonaka, MD, PhD, Shomei Ryozawa, MD, PhD VideoGIE Volume 3, Issue 3, Pages 83-84 (March 2018) DOI: 10.1016/j.vgie.2017.11.010 Copyright © 2018 American Society for Gastrointestinal Endoscopy Terms and Conditions

Figure 1 Strategy for EMR with use of an over-the-scope clip (OTSC) (EMRO). A, Chromoendoscopic image with indigo carmine dye. B, Marking of the border of the target lesion with the tip of an electrosurgical snare. C, Successful deployment of the OTSC outside marking (yellow arrows). Pseudoprotruding polyps above the OTSC. D, Deployment of endoscopic clip with dental floss near the marking. E, Resection with an electrosurgical snare above the OTSC. F, Post-EMRO defect without perforation or overt bleeding. G, Resected specimen. The lateral margin is free from tumor cells. H, Histopathologic examination revealing the tumor as a high-grade intraepithelial neoplasia with negative resection margins (H&E, orig. mag. ×100).
