Minimally Invasive Haemorrhoid Surgery

Transanal Haemorrhoidal Dearterialisation (THD) is a minimally invasive surgical procedure used to treat haemorrhoids.

THD is an operation to reduce the blood flow to the haemorrhoids. It is carried out under general anaesthesia and involves inserting a small ultrasound probe into the anus to locate the blood supply of the haemorrhoid which is then stitched.


The National Institute of Health and Care Excellence (NICE) recommends haemorrhoidal artery ligation surgery as a safe and effective procedure.


The procedure :

  • Causes less pain
  • Lower bleeding risk
  • Quicker recovery time
  • Patients often resume activities within 24 - 48 hours

Open Haemorrhoidectomy

This is the traditional operation to remove haemorrhoids.

Open haemorrhoidectomy is now used selectively for very large haemorrhoids.


The surgery is carried out under general anaesthesia but patients usually go home the same day or the next day. Most people need one or two weeks off work afterwards, depending on the extent of the surgery. Pain relief medication can help with the discomfort while your body heals.


There is a high success rate, with a 1 in 20 chance of haemorrhoids returning, which is lower than with non-surgical treatments.
