When a patient with chronic liver disease develops abnormal blood vessels in the esophagus, called varices, they are at significant risk of life-threatening hemorrhage. Esophageal banding is done to treat and eradicate these varices in the esophagus, either to prevent future bleeding or treat current bleeding. An endoscope is used to move small bands made of rubber down the throat until the varices are reached. The bands are placed around the varices, causing them to shrink.
Esophageal banding is used to treat varices in your esophagus. Esophageal varices are swollen veins in your esophagus, caused by cirrhosis or scarring in the liver that restricts normal blood flow.
