Band ligation or banding is an outpatient office-based technique. The basically the physician will have a banding device attached to a short proctoscope, or they can place it on the tip of a colonoscope depending and insert it into the anorectal canal. Generally when you do banding, it's primarily for internal hemorrhoids because as I mentioned earlier, the innovation, the nerves of the internal hemorrhoids is different than external. So you could safely place a rubber band around the dilated vein for an internal hemorrhoid, and it will ultimately cut through the vein and you'll just pass it in several days as if you are having a bowel movement. And so you can literally have your hemorrhoidal internal vein destroyed by this process.
