Three-Dimensional High-Resolution Esophageal Manometry Study of the Esophagogastric Junction in Patients with Achalasia

A novel three-dimensional high-resolution esophageal manometry provides a dynamic 360° representation of the pressure at the esophagogastric junction. To describe the three-dimensional high-resolution esophageal manometry patterns of achalasia. We retrospectively included all consecutive patients who underwent three-dimensional high-resolution esophageal manometry before and after treatment (pneumatic dilatation or per-oral endoscopic myotomy)...
