Herein, we demonstrate the application of various techniques including multiband mucosectomy for Barrett neoplasia (Figure 82.1); endoscopic submucosal dissection for Barrett neoplasia (Figure 82.2), squamous neoplasia (Figure 82.3), and early gastric cancer (Figure 82.4); submucosal tunneling endoscopic resection (Figure 82.5) and endoscopic full‐thickness resection (Figure 82.6) for esophageal and gastric subepithelial lesions; endoscopic mucosal resection for duodenal laterally spreading lesions (Figure 82.7); and endoscopic papillectomy for ampullary lesions (Figure 82.8).
