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.

In esophageal manometry studies, the pressure difference at lower esophageal sphincter (LES) was found to be 13,4 cm [H.sub.2]O in Group 1, 31.8 cm [H.sub.2]O in Group 2 and 4.3 cm[H.sub.2]O in Group 3.

Esophageal manometry,which evaluates motor function, may show nonspecific esophageal dysmotility in a few patients.
Esophageal manometry showed normal lower- and upper-esophageal sphincter pressure, but the wave patterns in the body of the esophagus were both peristaltic and non-peristaltic, with amplitudes at or above the upper limits of normal.
Study Design: Thirty-two consecutive Rett patients with a mean (range) age of 6.2 (2.3-14) years with prior history of feeding problems underwent esophageal manometry. Lower esophageal sphincter (LES) pressure and percent relaxation, mean peak esophageal body contractions, and percent of swallows with abnormal peristalsis were quantified.
Clinical symptoms in esophageal achalasia are nonspecific; definitive diagnosis requires assessment with barium swallow exam and, in some cases, esophageal manometry. In barium swallow, the esophagus appears markedly dilated, the lower esophageal sphincter opens sporadically and, therefore, the barium contrast moves very slowly into the stomach.
[] Esophageal manometry may be indicated prior to antireflux surgery.
Method of assessment/ Distance from follow-up pylorus/bougie size 1 Esophageal manometry 5 cm/36F preoperatively and at median interval of 7 months 2 High-resolution NR/NR impedance manometry Sleeve volume and diameter with CT scan Median follow-up at 11 months (1-50) 3 Clinically validated 6 cm/36F questionnaire, upper endoscopy, esophageal manometry, and 24-hour pH monitoring before and 24 months after LSG.
