Advice For GPs

The THD method, Transanal Haemorrhoidal De-Arterialisation (THD) is a minimally invasive surgical procedure used to treat Haemorrhoids

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

The THD procedure is 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.

General Information

The THD procedure doesn’t involve any cutting of tissue or open wounds. The patient can be discharged from hospital a few hours after the procedure without dressing or post operative care requirements.

The success rate is over 90% and the procedure can be performed again if required, with no detrimental effect to normal tissue anatomy or function.

Benefits of THD to the Patient:

– No open wound
– No need for any dressing
– Very little discomfort and no actual pain
– Quick return to normal activities and daily life

The National Institute for Health and Clinical Excellence (NICE) has issued full guidance to the NHS in England, Wales, Scotland and Northern Ireland on Haemorrhoidal artery ligation. NICE have recommended THD as an effective alternative to a traditional haemorrhoidectomy.

Please find below, the summary of the published interventional procedure on Haemorrhoidal artery ligation. The information on this page links to the published guidance and key documents from NICE.

The Interventional Procedure by NICE states: “Current evidence on haemorrhoidal artery ligation shows that this procedure is an efficacious alternative to conventional haemorrhoidectomy or stapled haemorrhoidopexy in the short and medium term, and that there are no major safety concerns”.

Therefore this procedure may be used provided that normal arrangements are in place for clinical governance, consent and audit.
