How much time do the bands last after esophageal varices surgery. do you have to have them replaced?

Esophageal banding: Esophageal banding essentially puts a "rubber band" like device around an enlarged blood vessel in the esophagus that is bleeding or at risk for bleeding. This banding essentially cuts off the blood supply. After this is performed the band will eventually fall off in a few days to a week. You might see the band pass in your stool. If you had banding done you may need again sometime in the future.
