A, Transverse mucosal incision in the esophagus proximal to the subepithelial lesion (SEL) for establishing a submucosal tunnel. B, A mucosal incision is made immediately distal to the SEL to allow access in the retroflexed position. C, Dissection in retrograde fashion through the second mucosal incision facilitated scope stabilization and completion of the resection. D, Mucosal incisions were adequately closed with through-the-scope clips. E, Final resected specimen, measuring 60 × 30 mm.
