Home Ksharsutra for Fistula

SIICP – World’s first integrated Colo-rectal care signifies the adaptability to successful procedures across AYUSH(Ayurveda, Yoga, Unani, Siddha, & Homeopathy) – Indian systems of medicine prevalent and practiced in India and some of the neighboring Asian countries.

Ksharsutra for Fistula is one of the successful Ayurveda treatment method with high success rate. Kshar Sutra (Seton) is an ayurvedic para surgical therapy for the management of anorectal disorders.

This therapy roots from Ayurveda by Charak, Sushruta and Vagbhata and its efficacy was established again by BHU’s Shalya Tantra Department. This technique is being practiced widely in India and also in some other countries.

Our chief surgeon Dr. Parameshwara C M  at SIICP treated a larger number of fistula cases using Kasharsutra procedure.

Kshar Sutra treatment is a safe method for Anal Fistulahemorrhoids and other sinus diseases. In this technique, a specially medicated thread is used.


Kshar Sutra for fistula is first prepared by coating a surgical linen thread gauge number 20 with Snuhi latex (Euphorbia nerifolia) for 11 times. Snuhi latex and Apamarga Kshara for 7 times and Snuhi latex and Haridra churna for 3 times.

The patient must be with local or spinal or general anesthesia while treatment. Then a malleable probe passes through the external opening of the fistula to the internal opening in the anal canal. And probe is gently taken outside along with a Kshar Sutra in the groove of the probe.

Later both ends of the Ksharasutra is joint together and replaces with a new one a week later. The Ksharasutra gradually cuts and heals the track. Finally, the whole fistulous tract heals after cutting.

How Ksharsutra helps in healing?

  • It helps in Cutting of the tract draining of the pus, curetting of unhealthy tissues. And healing of fistula occurs simultaneously as well.
  • Due to the caustic action, it removes the unhealthy tissue thus promotes healing
  • Controls infection by the microbicidal action.
  • Laying the tract open by cutting through the tissues.

One might experience mild post-procedural pain after the treatment. And this method requires multiple sessions.

There are various other treatments to treat fistula successfully. They are fistulectomy, fistulotomy, VAAFT ( Video Assisted Anal Fistula Treatment), LIFT and FiLAC ( laser-assisted closure).

Also, since these are minimally invasive techniques, there is absolutely no chance of sphincter damage leading to loss of bowel control. Surgeons recommend  “Kshar Sutra” for anal disorders because it is highly safe as well as highly effective.  And also  helps in quick recovery.

Diseases treated with Kshar Sutra by Dr. Parameshwara C M have the lowest recurrence rates so far.
