Information for the public

This procedure can only be done as part of a research study. This is because there is not enough evidence to be sure how well it works and how safe it is.

Haemorrhoids (piles) are enlarged blood vessels inside or around the anal canal (back passage). In this procedure, a catheter (thin tube) is used to place small metal coils or plastic particles into blood vessels supplying the area. This blocks them and reduces blood supply to the haemorrhoids. The aim is to shrink them, so relieving symptoms such as pain and bleeding.

NHS Choices may be a good place to find out more. NICE’s information on interventional procedures guidance has more about what a procedure is and how we assess them.

Is this procedure right for me?

If you’ve been offered this procedure, your healthcare professionals should discuss with you what is involved, and explain the research study, and tell you about the risks and benefits. They should talk with you about your options, and listen carefully to your views and concerns. Your family can be involved too, if you wish. All of this should happen before you agree (consent) to have the procedure and to be in the study. You should also be told how to find more information about the procedure.
