Combination of concurrent endoscopic submucosal dissection and modified peroral endoscopic myotomy for an achalasia patient with synchronous early esophageal neoplasms

Figure 2 Cardia was tightly closed and the resistance. A, B: Lesion at 24 cm from the incisor and Narrow-band imaging (NBI) with magnification revealed type IV intra-epithelial papillary capillary loops (IPCLs) according to Inoue’s classification; C, D: Another lesion at 32 cm, IPCLs were type V1; E, F: The third lesion in 34 cm IPCLs were type IV-V; G-I: The esophageal lumen below 30 cm was distorted and enlarged. The cardia was tightly closed; the resistance is significant.
