Esophageal Dilation: Before Your Procedure

What is esophageal dilation?

Esophageal dilation is a procedure that can open up narrow areas of the esophagus. The esophagus is the tube that carries food to your stomach. When this tube is too narrow, it is hard for food and liquids to pass through. This makes it hard to swallow.

During the procedure, the doctor guides a balloon or plastic dilator down your throat and into your esophagus. Then the device expands, like a balloon filling with air. It widens any narrow parts of your esophagus. To guide the balloon or plastic dilator, the doctor may use a thin, lighted tube that bends. (It is called an endoscope, or a scope.) Or he or she may use a thin wire as a guide.

You may get medicine to numb the back of your throat and help you relax during the procedure. You will not feel pain. You may go home after your doctor or nurse checks to make sure that you are not having any problems.

How do you prepare for the procedure?

Procedures can be stressful. This information will help you understand what you can expect. And it will help you safely prepare for your procedure.

Preparing for the procedure

	Be sure you have someone to take you home. Anesthesia and pain medicine will make it unsafe for you to drive or get home on your own.
	Understand exactly what procedure is planned, along with the risks, benefits, and other options.
	If you take a medicine that prevents blood clots, your doctor may tell you to stop taking it before your procedure. Or your doctor may tell you to keep taking it. (These medicines include aspirin and other blood thinners.) Make sure that you understand exactly what your doctor wants you to do.
	Tell your doctor ALL the medicines, vitamins, supplements, and herbal remedies you take. Some may increase the risk of problems during your procedure. Your doctor will tell you if you should stop taking any of them before the procedure and how soon to do it.
	Make sure your doctor and the hospital have a copy of your advance directive. If you don't have one, you may want to prepare one. It lets others know your health care wishes. It's a good thing to have before any type of surgery or procedure.

What happens on the day of the procedure?

Follow the instructions exactly about when to stop eating and drinking. If you don't, your surgery may be canceled. If your doctor told you to take your medicines on the day of surgery, take them with only a sip of water.

Follow your doctor's instructions about when to bathe or shower before your surgery. Do not apply lotions, perfumes, deodorants, or nail polish.

Take off all jewelry and piercings. And take out contact lenses, if you wear them.

At the hospital or surgery center

	Bring a picture ID.
	The procedure will take about 15 to 30 minutes.
	The doctor may spray medicine on the back of your throat to numb it. You also will get medicine to prevent pain and to relax you.
	You will stay at the hospital or surgery center for 1 to 2 hours until the medicine you were given wears off.
