Scientists from the University of Aberdeen and NHS Highland leading a study into methods of treating severe haemorrhoids are seeking volunteers.
A further 200 people are required to take part in the trial that will assess two techniques to treat the painful condition that affects around 50% of people in the UK at some point in their lives.
The study, funded by the National Institute for Health Research Health Technology Assessment (NIHR HTA) Programme, will compare the clinical effectiveness, cost effectiveness and patient acceptability of the methods.
One involves surgical excision. The other is a new technique where excess tissue is removed from haemorrhoids using a disposal stapling device.
Professor John Norrie, Director of the University of Aberdeen’s Centre for Healthcare Randomised Trials (CHaRT) said: “More than 20,000 haemorrhoidal procedures were performed in the UK in 2004/5 resulting in significant demands on health service resources.
“Our trial is the largest to date which seeks to understand the optimum technique to treat the condition.
“Our aim is to establish the method which is the least painful, and reduces complications and recurrence of the condition, which is beneficial from both a patient and clinical perspective.
Volunteers are being sought from across 31 UK hospitals including Raigmore, and Aberdeen.
Those wishing to take part should contact the research nurse at Raigmore Hospital, Kathleen MacLeod on: 01463 255836, kathleen.macleod3@nhs.net or the research nurse at Aberdeen Royal Infirmary, Louise Henderson on 01224 552206, louisehenderson2@nhs.net for further information.
