Laser surgery for hemorrhoids seems to work and is an alternative minimally invasive option, notes WebMD. This procedure involves the use of an electrical current or a laser to remove or reduce the size of the hemorrhoids.
Laser surgery might have fewer complications and less pain, but may not be as effective as a hemorrhoidectomy, according to WebMD. The use of a laser creates a scar tissue that prevents the supply of blood to the hemorrhoid, making it shrink or die. The number of laser treatments required depends on the patient and the condition, explains Manhattan Gastroenterology. Doctors commonly use laser surgery to treat small and medium-sized hemorrhoids.
