Treatment Overview
Infrared photocoagulation (also called coagulation therapy) is a
medical procedure used to treat small- and medium-sized hemorrhoids. During the
procedure, the doctor uses a device that creates an intense beam of infrared
light. Heat created by the infrared light causes scar tissue, which cuts off the blood supply to the
hemorrhoid. The hemorrhoid dies, and a scar forms on the wall of the anal
canal. The scar tissue holds nearby veins in place so they don't bulge into the
anal canal.
Only one hemorrhoid can be treated at a time. Other hemorrhoids may
be treated at 10- to 14-day intervals.
This medical procedure may be performed with other devices, such as
a
laser or electrical current, that also cut off a
hemorrhoid's blood supply.
Infrared photocoagulation is done in a doctor's office. You may
feel heat and some pain during the procedure. Afterward, you may have a
sensation of fullness in the lower abdomen, or you may feel as if you need to
have a bowel movement.
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.
- You may use mild pain relievers and sit in a
shallow tub of warm water (sitz bath) for 15 minutes at a time to relieve
discomfort.
- To reduce the risk of bleeding, avoid taking non-steroidal anti-inflammatory drugs (NSAIDs) for 4 to 5 days both before and after infrared coagulation.
- Health professionals recommend that you take stool
softeners containing fibre to ensure smooth bowel movements. If you strain
during bowel movements, hemorrhoids can recur.
Why It Is Done
Doctors recommend coagulation therapy in cases where small internal hemorrhoids continue to cause
symptoms after home treatment.
How Well It Works
The choice of treatment depends on the size of the hemorrhoid. The
success of the treatment depends on a variety of factors, including which
treatment is used and whether contributing factors (such as constipation) can
be changed.
- Small internal hemorrhoids are often
successfully treated with coagulation therapy. Large hemorrhoids are more
likely to be treated with rubber band ligation.
- One large study
comparing infrared photocoagulation therapy, rubber band ligation, and
injection sclerotherapy showed that infrared photocoagulation caused fewer and
less serious complications.1
Risks
Risks of coagulation therapy include:
- Considerable pain during the
procedure.
- Bleeding from the anus.
- Infection in the
anal area.
- Temporary inability to urinate.
What To Think About
The success of coagulation therapy depends largely on the doctor's
expertise and your ability to make changes in daily bowel habits that will make
passing stools easier.
Coagulation therapy is expensive, but it is less expensive than
surgery that requires a hospital stay and time away from work.
Not all doctors have the experience or the necessary equipment to
do coagulation therapy. This may help you decide which procedure to choose. Ask
your doctor which procedure he or she has done the most, how many times he or
she has done the procedure, and how satisfied people have been with the
outcomes.
Lasers have not been proven to be more effective than other forms
of treatment. Procedures using lasers are much more expensive, take longer, and
may damage surrounding tissue and cause more scarring.
