Esophageal Varices are abnormal, enlarged veins in the tube that connects the throat and stomach (esophagus). This condition occurs most often in people with serious liver diseases. Variceal banding is one method of treatment for esophageal varices that are at risk for rupturing. A lighted endoscope is used and an elastic band is placed around the bleeding esophageal vein. Banding the vein will cut off blood flow through the vein.
