Short term results of endoscopic submucosal dissection in superficial esophageal squamous cell neoplasms

Figure 1 Typical example case of ESD for esophageal neoplasm. A: Chromoendoscopy with iodine staining to demarcate the lesion from the non-neoplastic area; B: Marking placement around the lesion; C: Initial mucosal incision after submucosal injection at the distal margin of the lesions; D: Mucosal incision after submucosal injection at the proximal margin of the lesion and subsequent submucosal dissection from the proximal end; E: Mucosal defect after ESD; F: Resected specimen.
