THD uses a doppler to locate the terminating branches of the hemorrhoidal arteries. Once the artery is located the surgeon uses an absorbable suture to ligate or "tie-off" the arterial blood flow. The venous "out flow" remains to "shrink" the cushion. This is done without excision of tissue. If necessary the surgeon will perform a hemorrhoidopexy to repair the prolapse. Again, this is done with suture and no excision of tissue. This repair restores and "lifts" the tissue back to its anatomical position. The entire procedure is performed above the dentate line so that there is minimal discomfort. The procedure takes about 20 minutes and is offered as an out-patient surgery.
