Esophageal motor function: technical aspects of manometry

Gastrointest Endosc Clin N Am. 2014 Oct;24(4):527-43. doi: 10.1016/j.giec.2014.06.003. Epub 2014 Aug 8.


High-resolution manometry (HRM) has advanced the understanding of esophageal peristaltic mechanisms and has simplified esophageal motor testing. In this article the technical aspects of HRM are addressed, focusing on test protocols, in addition to concerns and pitfalls in performing esophageal motor studies. Specifically, catheter positioning, equipment-related artifacts, basal data acquisition, adequate swallows, and provocative maneuvers are discussed.

Keywords: Clouse plot; Dysphagia; Esophageal motor function; High-resolution manometry.
