A new era in esophageal diagnostics: the image-based paradigm of high-resolution manometry.

Background: The development of high-resolution (HRM) catheters and software displays of manometric recordings in color-coded pressure plots has changed the diagnostic assessment of esophageal disease. HRM may offer advantages over conventional methods, including improved identification of motility disorders, hiatal hernia, and outflow obstruction, and ease interpretation.

Study Design: HRM studies were obtained in 50 healthy volunteers and 106 patients.
