Fig 1 View of the dissecting endoscope in the distal extent of the submucosal tunnel using a retroflexed pediatric endoscope in the stomach. The 3-cm distance of the tunnel beyond the gastroesophageal junction is nicely verified.

Fig 4 Upper endoscopy after peroral endoscopic myotomy (n = 22) showed esophagitis in 55% of patients. The esophagitis was LA grade A (n = 3) or B (n = 8) in most patients. The single patient with LA grade D esophagitis had a concomitant hiatal hernia.
