High-resolution manometry (HRM) has significant contribution in the field of esophageal motility disorders recently. The development of HRM has categorized various esophageal motility disorders focusing on patterns of esophageal motor function. Additionally, the Chicago classification criteria are widely used for manometric diagnosis. HRM provides functional imaging of the esophagus. HRM has closely spaced pressure sensors and displays pressure variations as pressure topography plots. In the analysis of HRM according to the Chicago classification, a hierarchical categorization of motility disorders is made after evaluation of the individual swallow patterns. First the lower esophageal sphincter (LES) function, and subsequently the esophageal pressure patterns are used to make a diagnosis. The hierarchical flow-chart has 4 groups;①incomplete LES relaxation (achalasia or esophagogastric junction outflow obstruction), ②major motility disorders, ③minor motility disorders, ④normal esophageal motility. HRM is the gold standard for diagnosis of esophageal motility disorders.
