Banding is used mostly to treat 2nd degree piles, but you can also have it with 1st degree piles if medicines haven't worked for you. This procedure needs to be done using an endoscope. Your doctor will place a small elastic band just above the pile. This will cut off the blood supply to the pile, causing it to die and fall off after a few days. The area left behind will heal up naturally.
