Minimally invasive haemorrhoid treatment [THD]

Haemorrhoids, commonly known as ‘piles’, are swellings that appear in and around the rectum and anus, due to enlarged blood vessels.

What causes haemorrhoids?

They’re often seen in people who are prone to constipation and more likely to strain to pass bowel movements, and are also more common in people who are overweight and spend a lot of time sitting down. Pregnancy can also cause haemorrhoids, due to the increased pressure on blood vessels in the pelvic area.


They don’t always cause symptoms but can cause bleeding during bowel movements, as well as itching and discomfort. More severe cases can be painful and result in significant discomfort while going to the toilet or sitting, for instance.


If haemorrhoids are causing you any ongoing pain and problems and conservative treatments, such as creams and suppositories, haven’t helped, or your haemorrhoids have become severe, the expert team at Hadley Wood Hospital offer a range of treatment options. Many of these have good long-term results too, limiting the likelihood of your haemorrhoids returning in the future.

Transanal Haemorrhoidal Dearterialisation (THD) is a minimally invasive surgical procedure, during which your surgeon will use a very fine doppler ultrasound probe to carefully identify and locate the arteries supplying blood to the haemorrhoid. The arteries are then very gently sutured (stitched up), cutting off the blood supply to the haemorrhoid. THD is generally associated with very good long-term results, as well as a range of other benefits. It can usually be carried out as an outpatient procedure and post-surgery discomfort is generally minimal. You should be able to return to work and regular daily activities after a day or two.
