Removal of hemorrhoids with a surgical laser represents one of three basic types of hemorrhoidectomies performed by doctors, according to WebMD. Laser surgery is more expensive than traditional surgical techniques. The laser procedure takes longer and can result in deep tissue injuries.
Doppler-guided lasers helped doctors identify the ends of arteries, and minute lasers delivered pulsed shots to each of the affected blood vessels in patients studied in Italy in 2011, notes an article in Diseases of the Colon and Rectum. A total of 60 patients were analyzed following laser surgery or rubber band ligation. Six months after both procedures, 90 percent of laser surgery recipients reported symptoms were resolved versus 53 percent who had rubber band litigation. The Italian study concluded hemorrhoid laser procedures reduced post-operative pain and improved the quality of life more so than rubber band litigation.
A study of 750 patients who underwent laser surgery for hemorrhoids reported a success rate of 98 percent, says the Journal of Surgical Technique and Case Report. Doctors usually perform the outpatient procedure on patients with first-, second- or third-degree hemorrhoids. Smaller laser beams provide greater precision and accuracy as hemorrhoids are vaporized with one of two types of lasers.
