A new form of hemorrhoid surgery (hemorrhoidectomy) is called circumferential stapled hemorrhoidectomy. In this procedure, a circular stapler is used to staple the rectal lining just above the anorectal ring (border between the anus and rectum). This procedure works by pulling up the tissue that has become loose, preventing prolapse. While the hemorrhoids themselves remain, the symptoms they cause are relieved. This appears to be as effective as - and less painful than - traditional hemorrhoidectomy. However, research indicates that patients who undergo this procedure have an increased risk of hemorrhoid recurrence and prolapse.

Various minimally invasive therapies are generally preferred for most hemorrhoids. These involve the removal or shedding of hemorrhoidal tissues and the healing and scarring of the tissue left behind. The scarring causes the hemorrhoids to attach to the rectal wall. This prevents prolapse and reduces the risk of bleeding.

New surgical techniques are also being developed. These include doppler-guided hemorrhoid artery ligation. In this technique, sound waves (ultrasound) are used to identify the precise location of the artery supplying the hemorrhoid. This allows these arteries to be tied off without tying off the blood supply to the surrounding tissue. The blood supply to the hemorrhoids is cut off, destroying them. The theory of this technique is similar to that used in rubber band ligation.
