Infrared coagulation is the use of infrared radiation, which occurs under the influence of coagulation of the inner legs of the haemorrhoid. This infrared radiation in the form of a focused beam is applied to the site directly through the fiber.
An infra-red photocoagulation of using a special device - an infrared coagulator. It consists of a main unit, a manual applicator and a quartz fiber with a tip from a special heat-resistant polymer.
A beam of infrared light is fed through a quartz optical fiber to the leg of the haemorrhoid. Thermal energy causes coagulation of tissue - as if they are "welded". As a result of a hemorrhoidal node stops the blood flow, and it is gradually dying out.
Usually a single session of infrared photocoagulation can only handle a single node. Between treatments should be a gap in 10-14 days. In addition to infrared radiation, for coagulation can be used as a laser or electric current, but at present these techniques are used less frequently.
When shown the infrared photocoagulation
Infrared coagulation is indicated for the treatment of internal hemorrhoids, especially complicated by bleeding, first to the second stage. In addition, infrared photocoagulation performed and small bleeding internal hemorrhoids, which may remain after the ligation of latex rings or classical hemorrhoidectomy.
How is the procedure of infrared photocoagulation
When you perform this procedure, the patient is usually on the operating table or in a special chair with legs given to the abdomen, located on the stands. In the anal canal with an anoscope patient entered a special lamp. Anoscope is introduced into the anal canal so that the hemorrhoid was placed in its lumen. Tip coalescer is introduced into the lumen Once this is pressed and the vascular pedicle to the hemorrhoid. After that, she starts coagulation. With the help of a tip coagulation is carried out in 3 - 4 foot node points.
If you want to spend the whole procedure of infrared coagulation in a single step, as you can coagulate up to three piles. A second infrared coagulation is carried out 12-14 days after the first procedure. For large hemorrhoids 3-4 points further coagulate the surface of the site. During the procedure, patients often point increase in body temperature in the area of manipulation and, rarely, feeling like a needle stick. These events are usually held for one hour after the procedure.
At the later stage of hemorrhoids, when there may be also loss of nodes, you can use a combination of treatment methods, such as ligation of latex rings of large drop-down units and simultaneous coagulation of two smaller piles.
The results of infrared coagulation
Depending on what stage of hemorrhoids is the patient and the severity of his symptoms, require from one to six stages of coagulation. Maximum at a time you can spend an infrared coagulation of the three sites.
Usually after the procedure, the patient can coagulate in a few hours to celebrate a sense of discomfort. In some cases, during the first days after coagulation may be some pain, which is likely due to the coagulation of tissue in the sensitive zone of the dentate line.
After 7 - 10 days after the procedure, infrared coagulation, there may be bleeding, due to the falling away of necrotic hemorrhoid.
To reduce the risk of bleeding should avoid taking drugs such as aspirin and other nonsteroidal anti-inflammatory drugs for 4-5 days before and after the treatment of coagulation.
In addition, we recommend use of laxatives and drugs of plant fiber to avoid constipation. Constipation can be a cause of recurrence of hemorrhoids.
Possible complications of infrared coagulation
After infrared coagulation may develop the following complications:
thrombosis of the haemorrhoid,
necrosis of the mucous membrane of the haemorrhoid,
Pain after coagulation is usually associated with exposure to infrared radiation in the sensitive zone of the anal canal, which is located below the pectinate line. For relief of pain are commonly used analgesics, which can be combined with anti-rectal suppositories.
The risk of thrombosis of internal hemorrhoids after coagulation is associated with a greater area of plots of coagulation, which leads to the development of inflammation in the node. These phenomena can be cut short appointment of anti-inflammatory drugs.
