Fig. 3. The esophageal high-resolution manometry (HRM) and esophagography results of patient whose diagnosis was changed from ineffective esophageal motility by Chicago classification version 3.0 (CC v3.0) to achalasia by CC v4.0. (A) Marked dilation of the distal esophagus with food stasis is observed on esophagogastroduodenoscopy. (B) Esophagography shows esophagogastric junction narrowing with upstream esophageal dilatation and contrast media stasis. (C) The rapid drink challenge (RDC) test of HRM shows pan-esophageal pressurization supporting the diagnosis of achalasia (RDC integrated rapid pressure; 16 mmHg).
