Manometric Esophageal Length to Height (MELH) Ratio Predicts Hiatal Hernia Recurrence

Introduction: The shortened esophagus is poorly defined and is determined intraoperatively, as there exists no objective test to identify a shortened esophagus before surgical hiatal hernia repair. We devised a unique manometric esophageal length to height (MELH) ratio to define the presence of a shortened esophagus and examined the role of esophageal length in hiatal hernia recurrence. Patients and Methods: A retrospective review identified 254...
