The semirecumbent position for high-resolution esophageal manometry. Results of a feasibility study.

Objective: Normative values for high-resolution manometry (HRM) have been obtained with the patient lying supine. The aim of the study was to compare supine, semirecumbent and sitting positions during HRM in terms of variation in normative metrics, diagnostic yield, and patient's comfort.

Methods: A prospective, single-center feasibility study was planned in consecutive patients referred to the esophageal function laboratory.

Effect of Body Position on High-resolution Esophageal Manometry Variables and Final Manometric Diagnosis.

Background/aims: According to the Chicago classification version 3.0, high-resolution manometry (HRM) should be performed in the supine position. However, with the patient in the upright/sitting position, the test could more closely simulate real-life behavior and may be better tolerated.
