Fig. 2. Examples of high-resolution manometry (HRM) findings in patients with post-peroral endoscopic myotomy (POEM) integrated relaxation pressure (IRP) > 15.0 mmHg. (A) Type II achalasia before POEM (left) with IRP 42.2 mmHg, esophagogastric junction outflow obstruction (EGJOO) (peristaltic recovery) after POEM with IRP 20.1 mmHg (right). (B) Type I achalasia before POEM (left) with IRP 54.9 mmHg, persisting type I achalasia after POEM with IRP 18.7 mmHg (right). (C) Type II achalasia before POEM (left) with IRP 53.1 mmHg, EGJOO (peristaltic recovery) after POEM with IRP 17.5 mmHg (right).
