title: Measuring mechanical properties of the esophageal wall using impedance planimetry.
abstract: The mechanical properties of the esophagogastric junction (EGJ) are of major importance for the competence of the EGJ. Although manometry reliably measures sphincter pressure, no information is provided on distensibility, a crucial determinant of flow across the EGJ. Recently, a new technique, impedance planimetry, was introduced allowing accurate measurement of compliance or distensibility. This review discusses the recent advances in this area and highlights the clinical relevance of this new technique evaluating the mechanical properties of the esophageal wall and EGJ.
