Clinical Trial Summary

Endovascular embolisation is already a common procedure for bleeding haemorrhoids in the acute setting, where surgical options are not possible or have been exhausted. This pilot study aims to add to the small body of evidence that transarterial embolisation of symptomatic haemorrhoids is also safe and effective in the elective setting, providing a good alternative to conventional surgical management. This is a day case procedure that is performed under local anaesthetic. For selected patients, this presents a less invasive management option with reduced potential morbidity. For a health care system under significant financial stress, this provides a potential means of cost improvement, the extent of which this study will try and quantify. A series of 20 selected patients will be recruited to undergo this procedure and then followed up for 24 months. The long-term goal of this pilot study is to form the basis of a national registry of such procedures.

• Hemorrhoids

Intervention

Procedure:
• Trans-radial embolisation of haemorrhoids
Once patients have provided informed consent to participate, an assessment of symptom severity will be obtained during the initial visit using the a standardised set of 4 validated scoring systems used in research of haemorrhoidal disease. These include the French bleeding score (FBS), Goligher classification of internal haemorrhoids (GS), quality of life score (QoL) and Visual analogue score for pain (VAS). Routine blood tests will be taken. During the procedure, routine observations will be recorded on the paper CRF. The data collected on the paper CRF will be entered onto the electronic CRF. The Transarterial fluroscopically guided superior rectal artery embolization procedure will be performed on all participants. It is a day case procedure performed under local anaesthetic.
