Utility and standards in esophageal manometry

Abstract

Esophageal manometry is a specialized procedure used to evaluate lower and upper esophageal sphincter pressure, esophageal body contraction amplitude, and peristaltic sequence. The procedure is clinically useful in evaluation of a patient with nonstructural dysphagia, unexplained or noncardiac chest pain, a compendium of symptoms suggested because of gastroesophageal reflux disease, and in the preoperative evaluation for antireflux surgery. Manometric findings in 95 normal subjects evenly distributed across age groups were reported in 1987, and are the values still used in our and most laboratories today. The subsequent review will offer our "view" on the clinical utility of esophageal manometry, on the basis of years of experience and performance techniques that have remained constant over decades.
