(Esophageal Band Ligation)

 

Definition

Esophageal varices are abnormal blood vessels (veins) that develop in the esophagus. They have abnormally thin walls, and the blood pressure within them is very high. This combination makes esophageal varices very dangerous, because they can burst and cause life-threatening bleeding.
Endoscopic band ligation is the use of elastic bands to treat the varices. It is done as part of an upper gastrointestinal (GI) endoscopy.

What to Expect

Prior to Procedure

Anesthesia

  • Local—You may be given an anesthetic solution to gargle, or your throat may be sprayed with a numbing anesthetic.
  • You may also be given a sedative to help you relax.
  • Conscious sedation—You may be given medications through an IV. It will help you relax. Other medications will be given to treat any pain you feel during the procedure.
  • General anesthesia—If you are having the procedure due to uncontrolled bleeding you may need to have intubation and general anesthesia to inhaling blood.

Description of the Procedure

For this procedure, you will lie on your left side. If you are not intubated a mouthpiece will be placed to help keep your mouth open. An assistant will be in the room to monitor your breathing and heart beat. You may also be given oxygen through your nose. A suction tube will be used to clear the saliva and other fluids from your mouth.
A lubricated endoscope will be placed into your mouth. It will be passed down your throat and into your esophagus. The scope will have a small light and a camera. The doctor will watch the images on a video monitor. Air will be passed through the scope to help your doctor see your esophagus. The doctor will be able to locate the enlarged vein.
Instruments will be passed through the scope. The enlarged tissue will be sucked into the device’s chamber. One or more bands will be placed around the tissue to clamp off the blood supply.

How Long Will It Take?

Typically, less than one hour

Will It Hurt?

You will usually feel some pressure and discomfort, but not pain, during the procedure. After the procedure, your throat may feel irritated and sore.

Post-procedure Care

At the Care Center
You will be taken to a recovery area until the effects of your medications have worn off. In most cases, you will be observed for about an hour. If you feel well, you can then go home.
At Home
After returning home, you should do the following:
  • Follow your doctor's instructions regarding your diet.
  • Avoid driving or using heavy machinery for at least a day after your procedure. Sedatives may slow your reaction time.
  • Avoid drinking alcohol for at least a day after your procedure.
  • Get plenty of rest.
In the days or weeks after your procedure, the tissue that was banded will slough off.
Follow-up with you doctor as directed. You may need additional procedures.
