What is a seton? A seton is a thin silicone string (very similar to an elastic band) which is inserted into the fistula tract. This allows the fistula to drain and heal from the inside out. This procedure is normally carried out under general anaesthetic. This means you will be asleep throughout the operation.

How painful is seton placement?

It is normal to have pain for up to 1-2 weeks. Thereafter, you may notice discomfort with prolonged sitting and certain activities. Pain should not be constant or worsening. Placement of Setons may stimulate mucus production so the volume of drainage you are having may increase at first.

How long does a seton drain stay in?

You may have gauze and bandages over the opening of your fistula, and you may have a string coming from the fistula called a seton drain. The seton drain can help relieve symptoms and mark the fistula for doctors to fix later. It may stay in place for 6 weeks or longer.
