Reasons for Procedure
This is done to treat esophageal varices. These are abnormal blood vessels in the esophagus. They have thin walls and the blood pressure within them is very high. A burst blood vessel can be deadly.
Problems are rare, but all procedures have some risk. The doctor will go over some problems that could happen, such as:
- Excess bleeding
- Painful or difficult swallowing
- Damage to the esophagus
- Lung injury
Alcohol use disorder may raise the risk of problems.
What to Expect
Prior to Procedure
The surgical team may meet with you to talk about:
- Anesthesia options
- Any allergies you may have
- Current medicines, herbs, and supplements that you take and whether you need to stop taking them before the procedure
- Fasting before the procedure
- Whether you need a ride to and from the procedure
The doctor may give:
- Local anesthesia—the throat will be numbed
- IV medicines to help you relax
- General anesthesia—you will be asleep
Description of the Procedure
You will lie on your left side. A mouthpiece will be placed to help keep the mouth open. A scope with a small light and camera will be placed in the mouth and passed into the esophagus. Images will display on a monitor. Air will be passed through the scope to help view the esophagus better. 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. The tools and scope will be removed.
How Long Will It Take?
About 1 hour
Will It Hurt?
A sore throat is common in the first few days. It may be painful to swallow.
At the Care Center
The staff will give you medicine to ease pain. You will also be monitored for signs of problems, such as blood loss.
Recovery takes about a week. The tissue that was banded will be shed. You will have a smaller risk of bleeding from the blood vessels.
Call Your Doctor
Call your doctor if you are not getting better or you have:
- Signs of infection, such as fever and chills
- Pain that is not eased by medicine
- Bleeding from the mouth
- Nausea and vomiting
- Bloody vomit
- Problems swallowing
- Coughing, shortness of breath, or chest pain
- Bloody or dark black stools
- Severe belly pain
If you think you have an emergency, call for medical help right away.
