ABSTRACT

Esophageal manometry provides a detailed evaluation of esophageal contractility and, therefore, represents the reference method for diagnosis of esophageal motility disorders. Significance and clinical relevance have been further increased by implementation of high-resolution esophageal manometry (HRM), which reveals the functional anatomy of the esophagus in a visually-intuitive manner. The current 3 rd version of the international Chicago Classification (CC v3.0) gives standardized recommendations on performance and interpretation of HRM and serves as the basis for much of this expert consensus document. However, CC v3.0 gives only limited information with regards to the function of the lower and upper esophageal sphincters, the use of adjunctive tests including solid test meals and long-term ambulatory HRM measurements. In this expert consensus, we describe how to perform and interpret HRM on the basis of the CC v3.0 with additional recommendations based on the results of recent, high-quality clinical studies concerning the use of this technology to assess the causes of esophageal symptoms in a variety of clinical scenarios.
