At a glance
A seton is a thin piece of material — often a silicone loop, thread, or rubber band — that a surgeon places through a fistula tunnel. It keeps the tunnel open so it can drain rather than trapping infection inside.
Setons are commonly used when a fistula passes through a significant portion of the sphincter muscle, making a straightforward fistulotomy less suitable. Living with a seton takes some adjustment, but many people manage well once they find their routine.
This page covers what to expect day-to-day, how to manage comfort and hygiene, and when to seek care.
Why a seton is placed
Setons serve different purposes depending on the type:
- Draining seton (loose) — keeps the tunnel open and allows any infection to drain freely rather than forming a new abscess. This is the most common type.
- Cutting seton — gradually tightened over time to slowly divide the tissue. This is less commonly used today.
- Long-term seton — some people have a draining seton left in place for an extended period, particularly if other treatment options carry higher risk.
Your surgeon will explain which type you have and what the plan is going forward.
Daily life with a seton
Adjusting to a seton takes time. People commonly report:
- Awareness of the seton, especially in the first couple of weeks
- Some drainage from the fistula site, which is expected and often the whole point
- The seton becoming less noticeable over time as the body adjusts
- Being able to return to most normal activities within a few weeks
- Needing to carry spare pads or gauze for drainage management
- Occasional tugging or movement of the loop, which can be briefly uncomfortable
Hygiene and comfort
Keeping the area clean and dry is the most important daily task. People find these approaches helpful:
- Gentle cleaning after bowel movements — rinsing with warm water or using a bidet or peri bottle is often more comfortable than wiping.
- Sitz baths — soaking in warm water for 10 to 15 minutes can soothe the area and help keep things clean. Many people do this once or twice a day.
- Pads or gauze — a small pad in your underwear catches drainage and keeps clothing clean. Change it regularly.
- Loose, breathable underwear — cotton tends to be more comfortable than synthetic fabrics.
- Patting dry — after cleaning, gently patting the area dry rather than rubbing.
What tends to help
- Establishing a routine — once you have a system for cleaning and managing drainage, it becomes second nature for most people.
- Fiber and hydration — keeping stools soft reduces discomfort during bowel movements, which matters when there is a seton in place.
- Staying active — most people can walk, swim, and exercise with a seton. Start gently and see what feels comfortable for you.
- Carrying supplies — keeping a small kit with pads, wipes, and a spare pair of underwear can reduce anxiety about being away from home.
- Attending follow-up appointments — your surgeon needs to check the seton and the fistula regularly.
What tends to make things worse
- Pulling or tugging at the seton yourself
- Skipping hygiene routines and allowing the area to stay damp
- Tight clothing that causes friction against the seton site
- Ignoring new or increasing swelling near the seton
- Avoiding follow-up appointments
- Constipation and straining, which put pressure on the area
Drainage patterns
Some drainage is expected and is a sign the seton is doing its job. People commonly notice:
- More drainage in the first few weeks that gradually decreases
- Small amounts of fluid on pads — this may be clear, slightly yellow, or blood-tinged
- Occasional increases in drainage, sometimes related to activity or bowel movements
- The drainage pattern stabilising over time
A sudden increase in pain, swelling, or foul-smelling discharge is worth reporting to your doctor.
Talking to your doctor
At follow-up appointments, it helps to share:
- How the drainage has been — amount, colour, any changes
- Your comfort level day-to-day
- Whether the seton feels secure or if it has shifted
- Any new swelling, pain, or signs of infection
- How daily activities are going
- Questions about the next steps in your treatment plan
Many people live with a seton for weeks or months. It is okay to ask your surgical team about timelines and what comes next.
If you experience severe pain, heavy bleeding, fever, or symptoms that concern you, seek medical care.
