Esophagogastric junction outflow obstruction: Where are we now in diagnosis and management?

Figure 1 High-resolution manometry image. Panel A represents a normal high-resolution manometry (HRM) image of the esophagus with normal integrated relaxation pressure of 6 mmHg. Panel B represents an HRM image of esophagogastric junction outflow obstruction with IRP of 20 mmHg and reserved peristalsis.

Figure 2 A proposed algorithm for the management of esophagogastric junction outflow obstruction. HRM: High resolution manometry; TBE: Time barium swallow; LES: Lower esophageal sphincter; EGJOO: Esophagogastric junction outflow obstruction; DCI: Distal contractile integral; IRP: Integrated relaxation pressure; PPI: Proton pump inhibitor.
