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 or how safe it is.
An anal fistula is a narrow tunnel that forms between the end of the bowel and the skin near the anus. It may cause pain or discomfort and leak blood or pus. In this procedure, collagen paste is injected into the fistula. The paste fills the fistula, sealing it. The aim is to encourage healing.
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.
