A medicated seton, also known as ksharasutra, is a surgical thread that is used to treat anal fistulas:
How it works
A surgeon inserts the seton into the fistula, where it remains for several weeks to keep it open and allow it to drain and heal.
Benefits
Ksharasutra therapy is a minimally invasive procedure that is safe and effective, with low complication rates. It is ideal for patients who are elderly, have respiratory or cardiovascular diseases, or are unfit for surgery.
Results
In one study, all wounds healed well, and there was no incontinence or recurrence over a follow-up of 6 months to 2 1/2 years.
Complications
Local induration developed in 18 patients, and four had an abscess.
A seton can be made from a variety of materials, including silk, linen, rubber band, braided polyester, vascular loop, polypropylene, nylon, and cable tie.
Medicated setons, also known as ksharsootra, are generally safe and effective treatments for anal fistulas with low complication rates. However, some complications can occur, including:
Local induration: This can develop in some patients.
Abscess: This can occur in some patients.
Mucus leakage: It's common for mucus to leak from the wound after a seton stitch is inserted. This can make the area sore and itchy, so you might want to wear a pad and bathe more often.
Infection: All surgeries carry some risk of infection, including the fistulectomy procedure. If the infection isn't completely treated, it can continue inside the healing fistula. Antibiotics can usually treat a recurring infection.
Other complications that can occur after anal fistula surgery include:
Urinary retention
Heavy bleeding or discharge
Clot formation inside an existing hemorrhoid
Fecal impaction
Anal stenosis
Recurrence of the fistula
Bowel incontinence
Delayed wound healing
