Rubber band ligation (RBL) is an outpatient treatment for internal hemorrhoids of any grade. There are several different devices a physician may use to perform the procedure, including the traditional metal devices, endoscopic banding, and the CRH O'Regan System. With rubber band ligation, a small band is applied to the base of the hemorrhoid, stopping the blood supply to the hemorrhoidal mass. The hemorrhoid will shrink and die within a few days with shriveled hemorrhoidal tissue and band will falling off during normal bowel movements - likely without the patient noticing. Rubber band ligation is a popular procedure for the treatment of hemorrhoids, as it involves a much lower risk of pain than surgical treatments of hemorrhoids, as well as a shorter recovery period (if any at all). It is a very effective procedure and there are multiple methods available. When done with the CRH O’Regan System, it is also associated with a recurrence rate of 5% at 2 years. The procedure is typically performed by gastroenterologists, colorectal surgeons, and general surgeons. ==History== Ligation of hemorrhoids was first recorded by Hippocrates in 460 BC, who wrote about using thread to tie off hemorrhoids. In modern history, ligation using rubber band was introduced in 1958 by Blaisdell and refined in 1963 by Barron, who introduced a mechanical, metal device called the Barron ligator (similar to the McGivney). Dr. Patrick J. O’Regan, a laparoscopic surgeon, invented the disposable CRH O’Regan System. In 1997, the ligator was approved by the FDA for the treatment of hemorrhoids.〔(【引用サイトリンク】url=http://investors.crhsystem.com/about-us/ )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Rubber band ligation」の詳細全文を読む スポンサード リンク
