Rubber band ligation
Rubber band ligation is an outpatient treatment for second-degree internal hemorrhoids.
In this procedure, a small band is applied to the base of the hemorrhoid, stopping the blood supply to the hemorrhoidal mass. The hemorrhoid will then shrivel and die within 2 to 7 days. The shriveled hemorrhoid and band will fall off during normal bowel movements.
Rubber band ligation is a popular procedure, as it involves less pain than surgical treatments of hemorrhoids, as well as a shorter recovery period. Its success rate is between 60 and 80%.
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 device called the Barron ligator .
Rubber band ligation procedure is as follows:
- Pre-treatment diganosis and prescribed medications
- The patient is laid down on the left side, with knees drawn up and buttocks projecting over the operating table.
- Application of the band
Possible complications from rubber band ligation include:
- Band slippage or breakage
- Infection and pelvic sepsis
- Thrombosed hemorrhoids
- Anal fissure
Post-procedure instructions for patients
- Patient may experience some bleeding, especially after bowel movements. This may last for several days or more. If the patient thinks it is severe or persistent, patient should contact his/her doctor.
- Patient should not take Aspirin or anything containing Aspirin for at least 3 days.
- Acetaminophen or Ibuprofen could be taken for any discomfort the patient may feel. A warm bath for about 10 minutes, 2-3 times a day, may help.
