Injection sclerotherapy is a medical procedure used to treat small internal hemorrhoids. This fixative procedure uses a chemical that scars the tissues and cuts off the hemorrhoids' blood supply.
The doctor injects the chemical into the vein within a hemorrhoid. The chemical causes the vein to harden and the hemorrhoid tissue to die. A scar forms in place of the hemorrhoid on the wall of the anal canal. The scar tissue, which is firm and thick, holds nearby tissue and veins in place so they don't bulge into the anal canal.
The procedure is done in a doctor's office.What To Expect After Treatment
Bleeding from the anus occurs 7 to 10 days after the procedure, when the hemorrhoid falls off.
Bleeding is usually slight and stops by itself.
Doctors recommend injection sclerotherapy in cases where:
For small hemorrhoids, injection sclerotherapy relieves symptoms about as well as rubber band ligation. However, sclerotherapy does not work as well as ligation for large hemorrhoids.
Hemorrhoids often recur after injection sclerotherapy. Treatments can be repeated.Risks
Rare complications include:
Injection sclerotherapy is not a routine procedure and is done less often than other fixative procedures.
The success of injection sclerotherapy depends largely on the doctor's expertise in the procedure and your ability to make changes in your daily habits that will make passing stools easier. If hemorrhoids recur, injection sclerotherapy can be repeated, or another nonsurgical treatment can be tried.
Not all doctors have the experience or the equipment to do injection sclerotherapy. This may help you decide which procedure to choose. Ask your doctor which procedure he or she has done the most and how satisfied people have been with the outcomes.
