manometry

 [mah-nom´ĕ-trē]
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.

e·soph·a·ge·al ma·nom·e·try

measurement of intraesophageal pressures at one or more sites by intraluminal pressure-sensitive instruments.

Esophageal manometry

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.
Mentioned in: Achalasia

manometry

technique of using a manometer and interpreting the result.

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

American Gastroenterological Association technical review on the clinical use of esophageal manometry.
The clinical utility of esophageal manometry (EM) had never been formally examined, even though the test is ordered 100,000 times yearly in the United States, said Dr.
It is diagnosed on esophageal manometry by the presence of simultaneous, nonperistaltic esophageal contractions in 20% or more of wet swallows.
Pre operative evaluation should include upper gastrointestinal endoscopy, video esophageal, esophageal manometry, and 24-hour esophageal pH monitoring.

Patients were diagnosed with gastroesophageal cancer after a mean of 104 months of follow-up, which included a strict protocol including repeated esophagography, upper GI endoscopies with esophageal biopsy sampling, and esophageal manometry.
Esophageal manometry revealed that the patient had an incompetent lower esophageal sphincter (LES), based on a resting pressure of only 3 mm Hg (figure 2); normal LES resting pressure ranges between 15 and 35 iron Hg (figure 3).
Esophageal manometry revealed an LES pressure of 8 mmHg (normal: 10 to 45) with complete postswallow relaxation pressure at the gastric baseline (figure 1, B).
At our center, we believe that full esophageal manometry of the pharynx and esophageal sphincter is essential in patients with LPR to ensure accurate pH data.
Wiener et al studied 32 LPR patients with hoarseness and found that although pH monitoring was abnormal in 78%, esophageal manometry was normal in 100% and findings on esophagoscopy with biopsy were normal in 72%.
Testing for laryngopharyngeal reflux (LPR) can involve six different modalities: (1) the laryngeal examination, (2) ambulatory 24-hour double-probe (simultaneous esophageal and pharyngeal) pH monitoring, (3) esophageal manometry, (4) esophagoscopy or esophagography, (5) laryngeal sensory testing, and (6) intraluminal impedance monitoring.
