THD treatment for haemorrhoids

Transanal Haemorrhoidal De-Arterialisation (THD) is a minimally invasive surgical procedure used to treat haemorrhoids (piles). It can also be called Haemorrhoid Ligation, Haemorrhoidal Artery Ligation or Doppler guided Ligation.

The THD procedure is an innovative surgical treatment for haemorrhoids, approved by the National Institute for Clinical Excellence (NICE) and designed to cure haemorrhoids in a gentle way while focusing on excellent long term results.

The THD procedure

The THD procedure does not cut or remove any haemorrhoidal tissue, ensuring a minimum level of invasiveness and stress for patients.

The procedure is carried out under general anaesthesia, using an ultrasound Doppler to accurately identify the area of swelling and focuses on tying off the swollen artery, then lifting the prolapsed haemorrhoids while pulling the haemorrhoidal cushions back to their natural position.

It is a day surgery procedure.

During the THD procedure, the haemorrhoid's feeding arteries are precisely located via a Doppler ultrasound probe, mounted on a specially designed proctoscope.

Each of these arteries is then sutured through a small operating window of the same proctoscope, making this technique minimally invasive.

The procedure is carried out in the area above the dentate line, (an area without sensory nerves); the patient doesn't feel any stitches during or after the intervention.

The THD procedure can also re-position prolapsed tissue, restoring normal anatomy and physiology.

After the procedure

THD does not cut or remove any haemorrhoidal tissue; hence pain and post-operative complications are significantly reduced, with long term positive outcome.  

In most cases, patients resume their normal activities within 24 - 48 hours.

After the intervention, some patients might feel a slight discomfort in the rectal area which usually disappears within a few days.
