Hysteresis of the Lower Esophageal Sphincter: Relevance to the Pathogenesis of Esophageal Achalasia and its Phenotypes
{{output}}
Background & Aims: Hysteresis is a change in strain for a given repeated stress; it is a material property of the viscoelastic tissues. We aimed to determine hysteresis of the esophagogastric junction (EGJ) in patients with esophageal achalasia and differences... ...
