Medical Treatment

Some people require the following medical treatments for chronic or severe hemorrhoids:
Rubber band ligation: elastic bands are applied onto an internal hemorrhoid to cut off its blood supply. Within several days, the withered hemorrhoid is sloughed off during normal bowel movement.
Hemorrhoidolysis/Galvanic Electrotherapy: desiccation of the hemorrhoid by electrical current.
Sclerotherapy (injection therapy): sclerosant or hardening agent is injected into hemorrhoids. This causes the vein walls to collapse and the hemorrhoids to shrivel up.
Cryosurgery: a frozen tip of a cryoprobe is used to destroy hemorrhoidal tissues. Rarely used anymore because of side effects
Laser, infrared or BICAP coagulation: laser, infrared beam, or electricity is used to cauterize the affected tissues. Lasers are now much less popular.
Hemorrhoidectomy: a true surgical procedure to excise and remove hemorrhoids.
Stapled Hemorrhoidectomy: Also called the procedure for prolapse and hemorrhoids, it is designed to resect soft tissue proximal to the dentate line, which disrupts the blood flow to the hemorrhoids. It is generally less painful than complete removal of hemorrhoids and also allows for faster recovery times. It's meant for hemorrhoids that fall out or bleed and is not helpful for painful outside conditions.
Enema: This Practice is only used to clean the rectum in some cases and should only be done by a doctor. Water is injected into the rectum and then flushed out cleaning the area.
Doppler Guided Hemorrhoidal Artery Ligation : The only evidence based surgery for all grades of hemorrhoids. It does not involve cutting tissues or even a stay at the hospital; patients are usually back to work on the same day. Best treatment for bleeding piles, as the bleeding stops immediately.
