Rubber band ligation (RBL)[1] is an outpatient treatment procedure for internal hemorrhoids of any grade.
The hemorrhoid will shrink and fibrose within a few days with shriveled hemorrhoidal tissue and band falling off during normal bowel movements - likely without the patient noticing.
[3] 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).
When done with the CRH O’Regan System, it is also associated with a recurrence rate of 5% at 2 years.
[5] 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).
