Infrared photocoagulation (also called coagulation therapy) is a medical procedure used to treat small- and medium-sized hemorrhoids. This treatment is only for internal hemorrhoids.
During the procedure, a device is used 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.
Infrared photocoagulation is done as a OPD procedure. The patient may feel heat and some pain during the procedure. Afterward, there may be a sensation of fullness in the lower abdomen. Or feeling as if the patient may 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.
- 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 aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) for 4 to 5 days both before and after infrared coagulation.
- Take stool softeners that contain fiber to ensure smooth bowel movements. If you strain during bowel movements, hemorrhoids can come back.
Why It Is Done?
Doctors recommend coagulation therapy in cases where small internal hemorrhoids continue to cause symptoms after home treatment.
How Well does It Work ?
Infrared photocoagulation works for about 7 to 10 out of 10 people who have it. But improvements may not last. And 2 out of 10 people may need surgery.
Is there any risk associated with procedure?
Risks of coagulation therapy include:
- Considerable pain during the procedure.
- Bleeding from the anus.
- Infection in the anal area.
- Temporary inability to urinate.
