It is the name given to the pretense of dilated veins in the lower half of the esophagus. An increase in the pressure going through the veins can lead to thinning and result in major hemorrhage or bleeding that can endanger the patient’s life. The majority of the cases of esophageal varices are a result of a change in the circulation of blood in the liver. The ideal method to treat varices that are actively bleeding is to apply medical grade rubber bands through endoscopy to compress the veins and stop the bleeding. It is necessary to repeat the application of rubber bands in multiple sessions until the esophageal varices have vanished. This procedure lowers the mortality risk of the patient, as well as the need for blood transfusions.
