Common questions

What is an excision of an anal lesion?

This is the removal of a haemorrhoid (piles) or an anal fistula (a small abnormality in the anal region) by cutting it out.

Why have I been recommended to have an excision of anal lesion?

You may have been suffering from haemorrhoids (commonly known as piles), which are swollen blood vessels which develop inside and/or outside the anus. If they become infected, they can cause pain and discomfort and may need treatment. When haemorrhoids do not respond to other treatments, or if they are large, or external, or they bulge, surgical removal by excision may be the best solution.

You may have been suffering from an anal fistula, which is a small channel that develops between the end of the bowel and the skin near the anus. It’s usually caused by an infection near the anus resulting in a collection of pus (abscess) in the nearby tissue. An anal fistula can also occur after surgery to drain an anal abscess.

For some haemorrhoids, surgical excision may be the best treatment, particularly if they are large, or external, or they bulge. Haemorrhoids treated in this way, rather than by non-surgical means, are less likely to return. Anal fistulas very rarely heal by themselves, so surgical excision is the only way they can be treated.

What happens during an excision of an anal lesion?

The surgical excision of haemorrhoids (haemorrhoidectomy) involves the gentle opening of the anus so the haemorrhoids can be removed. The exact procedure to surgically remove an anal fistula will depend on the size and precise location of your fistula.

The operation will be carried out under general anaesthetic, so you’ll be unconscious and won’t feel any pain during the procedure. You may need to stay overnight at the hospital after the operation.

What should I expect after the procedure?

You'll probably need to take at least a week off work to recover. You may have some pain after the operation, perhaps for some weeks, which we’ll help alleviate with painkillers. You may have some bleeding and problems passing urine and stools.

Are there any risks from the procedure?

The operation is usually a successful treatment which most patients tolerate well with wounds that heal quickly. We’ll arrange to see you a few weeks after surgery to make sure the treatment has been fully successful
