Anal Fistula Surgery: Clarifying a Possible Seton Plan

If your surgeon has mentioned a possible “seton,” ask what that would mean for your operation and the days afterward. It is reasonable to want more than an unfamiliar word on a consent form, especially when you are trying to plan work, transport and help at home.

The operation may clarify the route

Guy’s and St Thomas’ June 2023 surgery information explains that the fistula’s relationship to the sphincter muscles is not always clear before surgery. Cutting those muscles can affect bowel control. A surgeon may use a seton for the section involving muscle and treat another section differently.¹

Ask what the team already knows about your fistula and what may become clearer during the operation. Request an explanation of the possibilities covered by your consent, including how the surgeon will decide among them.

You could say: “If you find that a seton is appropriate, please explain what you expect it to achieve and what happens after that.” Ask how the operation findings will be shared with you once you are ready to take in the information.

Plan for the findings you actually have afterward

The hospital describes the possibility of leaving surgery with both a wound and a seton. A seton can remain in place for several months to allow drainage; your own team should explain the intended duration and next step.¹

Before discharge, ask the team to identify what has been done and give you the written instructions that match it. Record whom to contact about the seton, whether another visit is planned and how you will hear about any further treatment.

If the explanation feels rushed, ask to go through it again with the person helping you at home, if you want them involved. Make sure the contact number and review arrangements are in the same place as the discharge instructions.

Home instructions should cover drainage and comfort

The recovery information notes that mucus drainage can occur with a seton and may irritate surrounding skin. The nursing team explains wound care. Ask for the cleaning and dressing instructions for your own procedure.²

Ask which supplies you need, how to use them and what changes should prompt a call. Have the team explain your prescribed medicines, toilet-care instructions and return to work or activity. Follow the instructions you receive rather than copying another person’s recovery routine.

Tell the team about practical concerns before discharge: difficulty reaching the area, limited help at home or uncertainty about managing the instructions. Ask who can assist if you cannot carry out the recommended care yourself.

Know when to seek help

Guy’s and St Thomas’ advises contacting the treating team for continuing wound bleeding and seeking urgent care for feeling generally unwell or developing a fever after surgery. Confirm your daytime and out-of-hours contacts before leaving.²

If a problem develops, describe what has changed and when it started. Keep the operation details available so the clinician knows which procedure you had and whether a seton was placed.
