The Value of High-Resolution Manometry in Measurement of EGJ Competency and Manometric Outcomes of Antireflux Surgery

Abstract

The esophagogastric junction (EGJ) barrier plays an integral role in the prevention of gastroesophageal reflux; however, not much attention has been paid to competency parameters, especially in the era of high-resolution manometry (HRM). HRM provides a unique spatiotemporal pressure profile and measurements of the EGJ. Herein, we discuss the evidence for objective measures of EGJ competency, which should guide the clinical management of gastroesophageal reflux disease. Additionally, we will briefly discuss expected normal values after antireflux surgery.
