Esophageal banding is a life-saving procedure to stop bleeding from esophageal varices. Esophageal varices are veins in the esophagus that have become wider and larger due to blockage in the flow of blood to the liver and or spleen. Varices usually form because the liver is scarred and allows little blood to flow through it. This results to increased pressure in the vessels that carry blood to the liver and eventual “backing-up” of blood flow. Often, the blood “backs up” to the veins of the lower esophagus, forming esophageal varices. Esophageal banding is done by putting little rubber bands on the varices using an upper endoscope, hence effectively tying them off to prevent further bleeding.
