Infrared coagulation is a procedure that applies a special type of energy, called infrared, to the base of an internal hemorrhoid. The energy causes scarring within the hemorrhoid, reducing the blood flow in the hemorrhoid and shrinking it. Most people feel a warm or slight burning sensation during the treatment, which lasts only a few minutes. People with extensive hemorrhoids may require more than one treatment. Compared to older techniques such as injection of a chemical solution, feezing, and band ligation, infrared coagulation is an effective treatment for internal hemorrhoid with fewer complications. Dr. Steven Shu performs this procedure in the Crystal office.
