High Resolution Esophageal Manometry with Impedance

Esophageal manometry is a test used to evaluate how well the esophagus muscles work to transport liquids/food from your mouth into your stomach. Esophageal manometry is typically performed to evaluate the symptoms of gastric reflux, heartburn, difficulty swallowing, regurgitation, and functional chest pain. This test may also beĀ used in preoperative evaluation for anti-reflux surgery or to determine esophageal distance measurement needed for performing ambulatory pH/Impedance diagnostic test.

How the test is performed

The test is performed by a doctor, nurse, or technician and usually takes less than 30 minutes. The patient is placed in a comfortable, semi-reclining, or reclining position. The nose and throat may be numbed with a spray or gel. This will minimize any discomfort associated with placing the small catheter through the nose and into the stomach. During this time, the patient will be able to breathe, swallow, and talk with ease. During the test the patient will be asked to swallow a number of times. The pressures resulting from swallowing action will be detected and recorded by tiny sensors located on the catheter. The recording will then be transferred to a report for the doctor to review and interpret.
