Esophageal Manometry

Manometry is the recording of muscle pressures within an organ.  Therefore, esophageal manometry measures the pressure within the esophagus.  It can evaluate the action of the stripping muscle waves in the main portion of the esophagus as well as the muscle valve at the end of it.  The equipment for manometry consists of thin tubing with openings at various locations.  When this tube is positioned in the esophagus, these openings sense the pressure in various parts of the esophagus.  As the esophagus squeezes on the tube, these pressures are transmitted to a computer analyzer that records the pressures on moving graph paper.  It is much like an electrocardiogram.  The physician can evaluate these wave patterns to determine if they are normal or abnormal.
