Upright Integrated Relaxation Pressure Predicts Symptom Outcome for Esophagogastric Junction Outflow Obstruction

Esophagogastric junction outflow obstruction (EGJOO) is characterized by elevated integrated relaxation pressure (IRP) and preserved esophageal peristalsis. The clinical significance of EGJOO is uncertain. This study aim to describe the clinical characteristics of these patients and to find out potential parameters to predict patients' symptom outcome.Consecutive patients who received high-resolution manometry examination in our hospital in...
