Transanal haemorrhoidal dearterialisation (THD/HALO)

An innovative, minimally invasive surgical procedure approved by NICE called Transanal haemorrhoidal dearterialisation (THD) - also called haemorrhoid ligation, haemorrhoidal artery ligature, or doppler guided ligature - involves blocking the flow of blood into a pile. With it, you can cure haemorrhoid's in a gentle manner and achieve excellent long-term results.

There is no cutting or removing of haemorrhoidal tissue, so postoperative complications are reduced.

In THD, your surgeon will use an ultrasound Doppler probe mounted on a specially designed proctoscope to locate the haemorrhoid's feeding arteries (which are located in the rectum). Through a proctoscope window, the surgeon will suture (close up with stitches) each of these arteries.

You won't feel any stitches during or after the procedure since it is performed in an area without sensory nerves. The THD treatment can also reposition prolapsed tissue (piles hanging down from your bottom).
