THD (Transanal Haemorrhoidal Dearterialisation)

THD (Transanal Haemorrhoidal Dearterialisation) is the least invasive new method for treatment of hemorrhoid. There is painless technique, which doesn’t require the excision of hemorrhoidal tissue and in the same moment eliminates symptoms of hemorrhoid.

This method comprise the ligation of hemorrhoidal arteries. The legation is applied in that area of rectum where sensory fibers are minimal, that is why patient does not feel pain and discomfort.


Transanal Haemorrhoidal Dearterialisation

THD can be applied also for fourth-degree hemorrhoid (in this case, other non invasive procedures are not effective).

If there is fourth-degree hemorrhoid, we ligate branches of superior rectal artery and after this we fix hemorrhoidal tissue in anal canal (it eliminates prolapse of hemorrhoid). There is advantages of THD comparing with other less invasive methods of treatment of hemorrhoid (sclerotherapy, rubber band ligation, infrared photocoagulation)

1. Radicalism

Transanal Haemorrhoidal Dearterialisation (THD) is based on reducing of arterial flow to the hemorrhoids and is high-effective in 95% of cases (elimination the symptoms of hemorrhoid). The radicalism of this technique is so high that it is even comparable with traditional operations.

2. One phase- technique 

All hemorrhoidal arteries are ligated at once in this case. Instead, other less invasive methods require 3-4 phase ( 1 phase – 1hemorrhoidal piles).

3. Less traumatic

THD doesn’t cause necrosis of hemorrhoidal tissue or wound. This method requires only ligation of hemorrhoidal arteries, that’s why discomfort and duration of rehabilitation after this procedure is minimal. After this operation patient can go home next day and can go to his normal activity in 3-4 days. In our department, we with our Italian colleagues performed THD firstly in Ukraine (at this moment we already accomplish 150 this operations). We have as well results as our foreign colleagues.

The THD is equipped with a Doppler transducer (A) to locate the terminal branches (up to six) of the superior rectal artery, which are then ligated, through an apposite slit (B) in the instrument, 2-3cm above the dentate line. Therefore, the arterial flow to the hemorrhoids is reduced and they shrink.
