An operation to cut away your haemorrhoids is called a haemorrhoidectomy. Your doctor may recommend this operation if you have third or fourth degree haemorrhoids. For a description of the categories of haemorrhoids, see What are haemorrhoids?
If you have a haemorrhoidectomy, you'll probably only need to stay in hospital for a few hours.
Your surgeon will cut away your haemorrhoids with a scalpel or surgical scissors.
They will then either close your wound with stitches or leave it to heal naturally.
If you have stitches, it's called a closed haemorrhoidectomy. If the wound is left to heal by itself, it's called an open haemorrhoidectomy.
It doesn't seem to make much difference whether you have stitches or not. Both operations seem to work about as well as each other. Your wound might heal slightly more quickly if you have stitches, but it won't affect how long you'll need to stay in hospital.
The research shows that an operation to get rid of your haemorrhoids works well. In one study, all the people who had an operation were still free of haemorrhoids one year later. Another study found that about 8 in 10 people still had no haemorrhoids a year after their operation.
There's also a newer operation that uses staples to reduce the blood supply to your haemorrhoids and shrink them.
