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.
Doctors recommend coagulation therapy in cases where small internal hemorrhoids continue to cause symptoms after home treatment.
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.
