In the Clinic “LEKAR” the entire Arsenal of the modern methods of treatment of proctological diseases and it’s complications is used. To ensure the high quality treatment and achieve a positive result is widely used minimal invasive outpatient techniques at early stages of the disease and modern methods of surgical operations in advanced and complicated pathological processes.
Transanal hemorrhoidal dearterialization (operation of THD)
Transanal hemorrhoidal dearterialization – a modern low-invasive method of hemorrhoid treatment developed by Italian scientists. The procedure is performed with virtually no blood loss, pain and discomfort for the patient, because it focuses on the area of the rectum where there are no pain receptors. Thanks to low-invasiveness, after the THD, a patient quickly recovers, and the symptoms of hemorrhoids disappear immediately after the operation.
The procedure of THD is as follows: the doctor with the help of special disposable Doppler sensor (A) determines the location of the ends of hemorrhoidal arteries bringing the blood to the hemorrhoidal nodes. (Fig. 1, Fig. 2). Then the found arteries are sewn through the window in the tool (B). Totally up to six sutures can be put on. After sewing of the branches of hemorrhoidal arteries, the blood supply of hemorrhoids reduces, they collapse immediately after the surgery and over time become overgrown.
Transanal hemorrhoidal dearterialization is universal – effective in 2nd, 3rd and 4th stages of chronic hemorrhoids. In case of Hemorrhoids of stage 4 not only the branches of the upper rectal artery is getting tied up (Fig. 1, Fig. 2), but also by a special surgical technique (pexy) hemorrhoidal tissue is fixed in the anal canal and the nodes then do not fall out of the rectum (Fig.4).
If we talk about the contraindications to the procedure, they are:
Any acute infection.
In the presence of chronic diseases, the possibility of applying the method will set the doctor.
The advantages of the THD are:
High efficiency. Transanal hemorrhoidal dearterialization minimizes the blood supply of changed hemorrhoids and gives an opportunity to achieve the disappearance of the main symptoms of hemorrhoids in 95% of cases.
Simultaneity. If, during the ligation of latex rings hemorrhoids, laser treatment of hemorrhoids 3-4 sessions of treatment is required, in case of transanal hemorrhoidal dearterialization one procedure is sufficient to tie up all the branches of the hemorrhoidal arteries. If the patient has a concomitant pathology – chronic hemorrhoids and anal fissure, is possible to simultaneously conduct two operations – the operation of excision of anal fissure and procedure of THD.
Low injury rate. After performing the THD there is no developing of necrosis of the mucosa, as in other minimally invasive methods of treatment. The wound surface is absent, which significantly improves the quality of life of the patient in the postoperative period and reduces the time of rehabilitation. In case of compliance of recommendations of the attending physician, the patient can be able to work in 2 days after the THD procedure.
