Fig. 1. Improved esophageal bolus clearance after peroral endoscopic myotomy (POEM) in a patient with esophagogastric junction outflow obstruction (EGJOO). A 50-year-old woman presented with dysphagia. (A) She was diagnosed as having EGJOO (integrated relaxation pressure, 41 mmHg) and showed abnormal liquid bolus transit (LBT; 0%). POEM was performed because no organic cause was found to explain her abnormal dysphagia. (B) After POEM, her symptoms disappeared completely, and the LBT was normalized as indicated by the purple color in the figure.
