Several years ago I reported on another technique used by Dr. Rudd. He also places a tiny band over the neck of the hemorrhoid, and then freezes it using nitrous oxide. The rubber band in both cases shuts off the blood supply to the hemorrhoid. Several days later the rubber band and the pile drop off. This leaves a raw area that takes two to three weeks to heal.
Most patients require one or two more visits to destroy remaining hemorrhoidal tissue.
Dr Salvati has removed 45,000 hemorrhoids this way. Prior to treatment the majority of patients complained of bleeding or protrusion. But if hemorrhoids are large, protrude and cannot be pushed back, surgery is required. The most common complication is a small blood clot occurring at the anal area. If the clot is large a small incision is made to remove it.
