If that happens, it could cause the formation of anabscess.
An abscess is a collection of pus that can lead to further complications.
It is threaded through the fistula.
This keeps the fistula open so that it may drain and heal more cleanly.
Conditions Associated With Fistula
A fistula can occur because of a disease or condition.
It is performed on an outpatient basis.
Patients are put under anesthesia for the placement of a seton.
There may be a preparation procedure before surgery.
The surgeon will give you any special instructions on how to prepare.
The two openings of the fistula will be identified and the seton will be threaded through it.
The seton may be knotted or otherwise connected so that it forms a continuous loop.
Who Does It?
In certain instances, a general surgeon may place the seton.
For a seton thats placed in the rectal area, your doctor may recommend that you use anenema.
General anesthesia may be used, which will require you to have an intravenous (IV) line placed.
There may be other medications given to prevent infection.
The procedure is done on an outpatient basis.
Outcomes/Recovery
You may be prescribed astool softenerafter the procedure.
Keeping the area clean will also be part of the aftercare process.
This could include takingsitz baths(sitting in warm, shallow water) or changing dressings as needed.
You may also be given prescription pain medication for use in the days after the procedure.
This should be taken as directed.
There will be follow-up visits to check the seton placement.
Summary
A seton is a flexible tube or thread that is placed through a fistula.
The seton is a step inhealing the fistulaand in preventing further complications.
A seton may be left in place for several weeks to several months.
Regular checkups will be needed to keep an eye on the fistula and the seton.
In addition, there could be a need for more than one seton if there are multiple fistulas.
