Fig. 2. Comparison of the contractility index and the distensibility index before/after peroral endoscopic myotomy (POEM) or pneumatic dilatation (PD) among achalasia subtypes. The contractility index: PD in type II achalasia increased significantly; POEM in type III achalasia increased significantly. The distensibility index: POEM in type I, II, and III achalasia significantly increased; PD in type I and II achalasia increased significantly.
