Banding is a medical procedure which uses elastic bands for constriction. Banding may be used to tie off blood vessels in order to stop bleeding, as in the treatment of bleeding esophageal varices.[1] The band restricts blood flow to the ligated tissue, so that it eventually dies and sloughs away from the supporting tissue. This same principle underlies banding as treatment for hemorrhoids.[2]
Banding may also be used to restrict the function of an organ without killing it. In gastric banding to treat obesity,[3] the size of the stomach is reduced so that digestion is slowed and the patient feels full more quickly.
