THD Method - Haemorrhoids

What is THD?

THD is designed to cure haemorrhoids in a gentle way, while focusing on excellent long-term results.

If you have been diagnosed with Grade 2, 3 or 4 haemorrhoids and your GP or consultant has recommended surgery, you may be eligible for THD, a NICE (National Institute for Clinical Excellence) approved procedure.

Transanal Haemorrhoidal De-Arterialisation (THD) is a minimally invasive surgical procedure (i.e. no tissue is cut or removed), that is carried out under a general anaesthetic.

It can also be called Haemorrhoid Ligation, Haemorrhoidal Artery Ligation or Doppler guided Ligation.

The procedure

The procedure is a minimally invasive type of surgery (i.e. no cuts are made into the tissue), and it is carried out under general anaesthetic.

During the THD procedure, the blood-supplying arteries of the haemorrhoid are precisely located with a fine, specially designed proctoscope allowing maximum precision via a Doppler ultrasound probe.

Each of these arteries is then gently sutured through a small operating window in the same proctoscope, making this technique extremely gentle and safe.

As 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.

Other information

The THD procedure differs from other surgical techniques in the following ways:

It does not cut or remove any haemorrhoidal tissue; hence post-operative complications are significantly reduced compared to a haemorrhoidectomy.

Since the blood-supplying arteries are sutured, the THD procedure has been associated with far less post-operative complications and better long-term results.

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

Due to its low recurrence rates compared to traditional types of surgery, the THD procedure has been adopted in numerous hospitals throughout Europe
