This information will help you prepare for your esophageal manometry procedure at Memorial Sloan Kettering (MSK).
Esophageal manometry measures the pressure in the esophagus (food pipe). This procedure is done to find out why you have symptoms such as difficulty or pain when you swallow or chest pain. It is also done before anti-reflux surgery. It does not require anesthesia (medication to make you fall asleep).
A Week Before Your Procedure
You may need to stop taking some of your medication before your procedure. We have included some common examples below. If you take medication to thin your blood, such as to treat blood clots or to prevent a heart attack or stroke, ask the doctor who prescribes it for you when to stop taking it. Some examples are aspirin, warfarin (Coumadin®), dalteparin (Fragmin®), heparin, tinzaparin (Innohep®), enoxaparin (Lovenox®), clopidogrel (Plavix®), and cilostazol (Pletal®).Back to top

When it’s time for your procedure, you will be brought into the room where it will be performed. Your doctor will pass a thin tube through your mouth or nose and into your stomach. When the tube is in place, you will be asked to swallow small sips of water. The pressure of the muscle contractions will be measured along several sections of the tube.
