The effect of a sitting versus supine posture on normative esophageal pressure topography metrics and Chicago Classification diagnosis of esophageal motility disorders

摘要

Background and aimsAlthough, the current protocol for high resolution manometry (HRM) using the Chicago Classification is based on the supine posture, some practitioners prefer a sitting posture. Our aims were to establish normative esophageal pressure topography (EPT) data for the sitting position and to determine the effect of applying those norms to Chicago Classification diagnoses.
