Abstract excerpt
BACKGROUND AND AIMS: Esophagogastric junction (EGJ) integrity influences gastroesophageal reflux disease (GERD) pathophysiology, but its association with positional reflux patterns remains unclear. This study evaluated whether upright and recumbent acid exposure differs based on EGJ status on high-resolution manometry (HRM). METHODS: Retrospective study of patients undergoing HRM and 24-h pH-impedance monitoring...
