The major use of esophageal manometry is to measure pressure within the esophagus to assist in the diagnosis of esophageal pathology including aperistalsis, spasm, achalasia, esophagitis, esophageal congenital webs, scleroderma, hypermotility, and hypomotility. Esophageal manometry is mostly used in difficult diagnostic cases and as an adjunct to X- rays and direct via endoscopy.
24 hour esophageal pH impedance is for patients who are suspected of having gastric reflux and present with atypical symptoms or the patient's symptoms are suggestive of reflux, but conventional tests have not confirmed the presence of reflux.
High Resolution Esophageal Manometry
Esophageal manometry is a test to measure the strength and function of the esophagus (the “food pipe”). Results can help identify causes of heartburn, swallowing problems, or chest pain. The test can also help plan surgery and determine the success of previous surgery. Everyone has some reflux at various times. However, severe reflux may damage the lining of the esophagus and cause symptoms such as heartburn, regurgitation, chest pain, difficulty swallowing, hoarseness, cough and/or asthma.
Esophageal manometry is a procedure to measure the strength and function of the esophagus (the tube that goes from your mouth to your stomach). Results can help identify causes of heartburn, swallowing problems, or chest pain. A small, flexible tube will be inserted through your nose and down into the esophagus and stomach. The tube has a number of pressure sensors in it which will measure how your esophagus muscles work. Your nose and throat will be numbed
to minimize any discomfort as the tube is inserted. You will be able to breathe and swallow normally while the tube is in place. You will be asked to swallow 10-15 small amounts of salt water & jelly like substance during certain portions of the procedure. The tube will be in place for 30-40 minutes and then it will be removed. You will not be sedated during this procedure, and you will be able to return to your normal daily routine after the procedure.
Ambulatory pH procedure (24-hour) measures the amount of acidic stomach contents and gas backing up into the esophagus. This “reflux” of stomach contents can occur at different times throughout the day, so this test takes measurements constantly over a 24-hour period. A small probe (catheter) will be inserted through your nose and down into the esophagus. Your nose and throat will be numbed to minimize any discomfort as the tube is inserted. This probe will be connected to a recording device which you can wear. You will be asked to keep a diary of your activities during the 24-hour period, and will be instructed on activating a few simple buttons on the device. You will be able to breathe, eat and talk normally during the test.
Preparing for the Test
Be sure to talk to your doctor about any medications you take. Some medications can affect the test results. Also ask any questions you have about the risks of the test. These include irritation to the nose and throat. Be sure not to smoke, eat, or drink for up to 12 hours before the test.
During the Test
Manometry takes about an hour. Usually you lie down during the test. Your nose and throat are numbed. Then a soft, thin tube is placed through the nose and down the esophagus. At first you may notice a gagging feeling. You will be asked to swallow several times. There are 32 pressure channels and 16 impedance channels along the tube that measure both pressures and clearance with each swallow. We also use the most current technology to visualize the pressures. The Chicago classification uses topographic plots which correlate to the tracings that have traditionally been used for evaluating intraesophageal pressures. Both are helpful in determining the patient's esophageal motility.
After Esophageal Manometry
You’ll probably discuss the results of the test with your doctor at another appointment. This is because time is needed to review the tracings. You may have a mild sore throat for a short time. As soon as the numbness in your throat is gone, you can return to eating and your normal activities.
