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 .

Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:
Some factors that may increase the risk of complications include:
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 heartbeat. 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.
Typically, less than 1 hour
You will usually feel some pressure and discomfort, but not pain, during the procedure. After the procedure, your throat may feel irritated and sore.
