The patient is administered with anaesthesia. It can be local or spinal or general anaesthesia.
Following anaesthesia, a malleable probe is passed through the external opening of the fistula to the internal opening of the fistula located in the anal canal.
The probe is gently taken out through the inner anal opening to outside along with kshara sutra. The kshara sutra is fitted in the groove of the probe inserted into the tract of the fistula.
Both the ends of kshara sutra (alkali thread) i.e. one end in the external opening and the other end at the internal opening of the fistula are tied together.

The kshara sutra is left in place and the patient discharged. After one week the old kshara sutra is replaced by a new one. Change of kshara sutra enhances teh effectiveness of the treatment and the fistula will be healed in quick time.
Over a period of time (during its application), the kshara sutra gradually cuts the tract of bhagandara and eventually heals it. Finally the whole fistula gets cut and healed.
