The surgical removal of hemorrhoids.
Surgical procedure for tying and excising hemorrhoids.
Surgical removal of hemorrhoids, swollen or enlarged veins in the anal canal. Doctors use a number of different methods to remove painful or bleeding hemorrhoids. In a traditional hemorrhoidectomy, the veins are stretched and surgically cut at the base. This procedure is done in a hospital, and medication is given to cope with pain during the first bowel movements after the operation. It is more common, however, for hemorrhoids to be removed in outpatient procedures that may not even require anesthesia. In ligation, a flexible band is placed tightly around the base of each hemorrhoid. The lack of blood flow painlessly withers the hemorrhoid within a few days. Other options include destroying hemorrhoids with a laser; cryosurgery (destroying by freezing); sclerotherapy (shrinking the hemorrhoids by injecting chemicals); or shrinking them with electric currents.
The surgical operation for removing hemorrhoids, which are tied and then excised. Possible complications are bleeding or, later, anal stricture (narrowing). The operation is usually performed only for second or third-degree hemorrhoids.
The excision or destruction of hemorrhoids by one of several techniques, including traditional surgery, cryosurgery, laser surgery, infrared photocoagulation, latex band ligation, and sclerotherapy. The latter three modalities are used exclusively for internal hemorrhoids.
