For persistently bleeding hemorrhoids, doctors recommend minimally invasive procedures, such as rubber band ligation, chemical injection and infrared, laser or bipolar coagulation, according to Mayo Clinic. For more severe cases, doctors may perform surgery, including hemorrhoidectomy or hemorrhoid stapling.
The most common procedure for dealing with bleeding hemorrhoids is band ligation, reports Harvard Medical School. In this procedure, small elastic bands are placed around the hemorrhoid, causing it to shrink and the surrounding area to scar and heal. This usually requires up to four different trips to the doctor's office about eight weeks apart from each other.
For an injection procedure, a doctor injects a chemical solution into the affected area, but this treatment is usually less effective, according to Mayo Clinic. Through laser or infrared treatment, the hemorrhoids harden and shrivel, but this also leaves a higher chance of hemorrhoid recurrence.
During a hemorrhoidectomy, a surgeon removes any tissue that may cause bleeding, states Mayo Clinic. This is often the most effective way to remove hemorrhoids. Hemorrhoid staples block the flow of blood to the infected area and cause much less pain than a complete removal; however, stapling is not as effective and leaves a greater risk that hemorrhoids recur. For those over the age of 70 or in poor health, doctors prefer to use the minimally invasive procedures before resorting to surgery, according to WebMD.
