Su1017 POEM FOR ESOPHAGOGASTRIC JUNCTION OUTFLOW TRACT OBSTRUCTION: AN INTERIM MULTICENTER STUDY

Esophagogastric junction outflow obstruction (EGJOO) is a rare but increasingly recognized, newly described disorder typically presenting with dysphagia and chest pain. On manometry it is characterized by failure of the lower esophageal sphincter (LES) to relax with wet swallow reflected by an elevated integrated relaxation pressure (IRP), yet with some preserved esophageal peristalsis, thus not fulfilling the diagnostic criteria for achalasia. At present there is no well-defined management algorithm thus pharmacotherapy, botulinum toxin injection, pneumatic dilation, and surgical myotomy are all used in everyday care with mixed results.
