ShalyaTantra has wide scope in the management of Bhagandara(fistula-in-ano). Most recognized therapy for the management of Bhagandara is KsharaSutratherapy.AcharyaSushruta  has mentioned in NidanaSthana.According to modern science a fistula is a abnormal passage way between two organs of the body or between an organ and the exterior of the body. But we are concern here Bhagandara  means fistula in ano.

Fistula in ano is a condition which has been recognized as difficult surgical disease in all the ancient and modern medical sciences of the world. It is the recurrent nature of this disease which makes it more and  more difficult for treatment. It has been categories as a surgical condition and almost all the surgeons from Sushruta and also down to the modern reputed surgeons of present times have realized that difficult course which this disease offer for its surgical /medical /medico surgical methods of treatment. But a multi dimensional or divergent approach to the treatment for a single disease is only suggestive of the fact that none of these methods is complete and satisfactory. Even AcharyaSushruta have been realized the necessity of para-surgical approach. To overcome these recurrent nature of Bhagandara needs more and more comparative study. The present study is undertaken as mentioned in Chakradutta5^th chapter “Arshachikitsaadhyaya”&46^th chapter “Bhagandarachikitsaadhyaya”&Bhaisajyaratnavali 50^thchapter“Nadivranachikitsaadhyaya”. Fistula in ano is an infective disease of anal canal usually caused by cryptoglandular infection  of anal crypts. In fistula in ano there is an abnormal communication between two epithelial surface and the track  is lined by unhealthy granulation tissue. Intercepion Of Fistulous Tract With Application Kshar sutra [IFTAK] technique with kshar sutra proved to be very effective and conduct interception of fistlous tract with application of kshar sutra.

interception of fistulous tract with application of kshar sutra (IFTAK) is being practiced for treating complex and recurrent fistula in ano. In this technique proximal part of fistulas track is intercepted at the level of external sphincter along with the application of kshar sutra from site of interception to the infected crypt in anal canal .This is aimed at to eradicate the infected anal crypt with minimal damage to anal sphincter by using ksharsutra (medicated seton).Use of ksharsutra cause extensive fibrosis and favour  proper healing which reduce the chance of reccurence.
