the measurement of pressure by means of a manometer.
esophageal manometry a diagnostic study to assess the competence of the lower esophageal sphincter. A catheter sheathed with a water-filled balloon is inserted nasally and advanced into the esophagus; a series of measurements reflecting esophageal resting pressures are taken as the catheters are moved.
measurement of intraesophageal pressures at one or more sites by intraluminal pressure-sensitive instruments.
A test in which a thin tube is passed into the esophagus to measure the degree of pressure exerted by the muscles of the esophageal wall.

a method of recording pressures within the esophagus, particularly during the passage of a food bolus.
