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; (1) incomplete LES relaxation( achalasia or esophagogastric junction outflow obstruction), (2) major motility disorders, (3) minor motility disorders, (4) normal esophageal motility. HRM is the gold standard for diagnosis of esophageal motility disorders.
高分辨率测压法（HRM）近来在食管动力障碍领域有着重要贡献。HRM的发展依据食管运动功能模式对各种食管动力障碍进行了分类。此外，芝加哥分类标准被广泛用于测压诊断。HRM提供食管的功能成像。HRM具有间距紧密的压力传感器，并将压力变化显示为压力地形图。在根据芝加哥分类对HRM进行分析时，在评估个体吞咽模式后对动力障碍进行分层分类。首先评估食管下括约肌（LES）功能，随后利用食管压力模式进行诊断。分层流程图有4组：（1）LES松弛不完全（贲门失弛缓症或食管胃交界部流出道梗阻），（2）主要动力障碍，（3）次要动力障碍，（4）食管动力正常。HRM是诊断食管动力障碍的金标准。
