High-resolution Manometry can Characterize Esophagogastric Junction Morphology and Predict Esophageal Reflux Burden
Background:
High-resolution manometry (HRM) allows characterization of esophagogastric junction (EGJ) morphology and identification of hiatus hernia using novel software tools.
Aim:
The main purpose of this study was to determine the impact of HRM-based EGJ and lower esophageal sphincter (LES) metrics in predicting abnormal reflux burden.
Methods:
Total, upright, and supine acid exposure times (AETs) were extracted from ambulatory reflux monitoring performed off therapy in 482 patients (54.2±0.6 y, 63.3% female patients). EGJ morphology was categorized into type 1 (superimposed LES and crural diaphragm), type 2 (
