Anal Fistula — Living with a Seton
Hygiene, activity, and patience while the seton bridges to safer closure
A seton may stay for weeks to months. The aim is to dry out infection and make a second procedure safer. Most people adapt to work and daily life; early discomfort is expected. A seton is usually a temporary bridge — not a plan to live with thread forever — though selected Crohn’s cases may use long-term control.

Figure summary
This educational figure shows: Living with a seton.
Key points
Hygiene
Warm shower or sitz bath daily. Do not scrub hard. Pads control staining. Report a slipped or excessively tight thread.
Activity
Walking is fine. Heavy sport and cycling may be limited early. Sexual activity depends on comfort — ask your surgeon.
How long does it stay?
It depends on the plan. When discharge settles, LIFT, flap, laser, or another second stage may be discussed. Some patients keep a loose seton longer for control.

Warning signs and visit prep
Mild discharge with a seton is common. Sudden swelling, high fever, foul heavy pus, severe pain, or a seton that falls out or buries into skin needs early review. Bring notes on discharge amount, medicines, and daily limits — timing of the next stage often depends on that.
- Fever or new swelling
- Thread slipping or excessive tension
- More discharge or smell change
Frequently asked questions
Is discharge normal with a seton?
A small amount of serous or purulent drainage is expected — keeping drainage open is part of the point. Rising discharge with fever or new swelling needs review.
Can I shower and use the toilet?
Yes. Gentle warm water cleaning is fine; do not scrub. Rinse after stooling and use a clean pad for comfort.
What if the seton breaks or falls out?
Do not try to replace it yourself. Contact your surgical team the same day, especially if pain or swelling appears.
