WebAbstract. High-resolution manometry (HRM) with 36 pressure transducers spanning the esophagus has revolutionized the diagnosis and treatment of esophageal motility disorders, especially with respect to achalasia. The three major contributions of HRM are as follows: (a) Integrated relaxation pressure (IRP) at the esophagus gastric junction (EGJ ... Web1 de jul. de 2024 · Elevated integrated relaxation pressure (IRP) on esophageal high-resolution manometry (HRM) identifies obstructive processes at the esophagogastric junction (EGJ). Our aim was to determine whether intrabolus pressure (IBP) can identify structural EGJ processes when IRP is normal. In this observational cohort study, adult …
