Dear all

The study has now closed and the final results were published in the Lancet scientific journal on 7th October 2016.

Many thanks to all who took part and allowed us to answer this important research question. A newsletter will be sent to all participants at the beginning of the new year with further information.

Following the analysis of the 2-year results, we will no longer be completing 5-year follow-up. However we would like to take this opportunity to thank everyone who received and completed this questionnaire.  

eTHoS - the question

Is stapled haemorrhoidopexy (SH) more effective and cost-effective compared with traditional excisional haemorrhoidectomy (TH)? 


Haemorrhoids are swellings around the back passage which can cause bleeding, pain and itching and can protrude. When they become enlarged, surgery is often advised as it is an effective way to control symptoms. There are two major surgical treatments for haemorrhoids:

- Stapled surgery (SH) involves cutting away a ring or 'donut' of tissue above the swellings and special staples are used to join the tissue again.

- Traditional surgery (TH) involves removal of the swellings.
