Upright Integrated Relaxation Pressure Facilitates Characterization of Esophagogastric Junction Outflow Obstruction

Under the Chicago Classification of esophageal motility disorders, esophagogastric junction outflow obstruction (EGJOO) includes a varied clinical spectrum that results in diagnostic and management difficulties. We aimed to demonstrate that including upright swallows during high-resolution manometry (HRM) helps identify patients with clinically significant EGJOO.
