High Resolution Esophageal and Pharyngeal Manometry High Resolution Esophageal Manometry: Manometry is an in-office test to evaluate how the swallowing muscles in the esophagus and throat are working when food gets "stuck" or there is a bothersome "lump" in the throat. The test takes a few minutes with the patient wide awake. Some "numbing spray" is used and a very thin tube is swallowed. Some people may gag a bit, but most everyone tolerates the procedure well. Several swallows of liquid are completed to measure the swallow function. The test is completed in a few minutes. How Manometry Helps: Your physician may order high-resolution manometry to assess the muscle function of the esophagus for several purposes: to provide preoperative evaluation for corrective reflux surgery; to offer postoperative evaluation of swallowing in patients after corrective reflux surgery or after treatment of esophageal movement disorders; information prior to 24 Hr Esophageal pH monitoring to assess the correct location for proper positioning of the sensors; or evaluation of esophageal movement problems associated with systemic diseases.
