AimTo present application of Chicago classification criteria of esophageal motility disorders defined in high resolution manometry in clinical practice.Materials And MethodsHigh-resolution manometry is the most exact hi-tech diagnostic method for esophageal motor function disorders according to Chicago classification v3.0. Uniqueness of the method consists in capacity to define integrated quantitative and qualitative metrics of esophageal contractile function and to establish their specific disorders e.g.: change of intrabolus pressure at disorders of esophagogastric junction (EGj) outflow, hypercontractile esophagus, fragmented contractions and weak or failed peristalsis, distal esophageal spasm. Assessment of the type of achalasia subtypes has significant impact on the patients' treatment choice. According to anatomical location of the lower esophageal sphincter and crural diaphragm several morphological types of gastro-esophageal junction are defined that determine severity of gastroesophageal reflux disease. Multiple rapid swallow responses during esophageal high-resolution manometry reflect esophageal body peristaltic reserve and is a predictor of postoperative complications. Differential diagnosis of belching type became possible at combined application of high-resolution manometry and impedance measurement.ResultsConclusionHigh-resolution manometry is a fundamental diagnostic test of esophageal motor function disorders. Clinical application of this method significantly expands diagnostic potential and allows to carry out personalized treatment that increases treatment quality.
