The area in and around anal region is some time affected with pain swelling and pus or watery discharges. This abnormal presentation may be due to anal fistula. It is characterized by a nodular swelling in or around anal region with occasional pain and watery or blood mixed pus discharge. The symptoms might be mild but as the time passes the fistulous tract may become deep and develop multiple branches with multiple openings. This makes the treatment more difficult. Therefore it is always advisable as soon as this condition is diagnosed it should be treated promptly to avoid further complications. 

Causes: The causes of anal fistula are many. The major reason is the formation of pus. Incompletely cured abscess, microbial infection, ulcers, inflammation of anus and the region around it, and complications that arise out of a surgery can cause the anal fistula. The individuals suffering with diabetes, ulcerative colitis, malignancies and also individuals undergoing chemo or radiotherapy or having some other immune compromised conditions are prone to develop anal fistula. 

Treatment: Practically it has been noticed that any amount of oral medications either from allopathy/ homeopathy or Ayurveda is not of much help. In allopathy the surgeons usually advice Fistulectomy i.e. complete excision of fistulous tract or VAAFT – Video Assisted Anal Fistula Treatment. However in both these case a fairly high incidence of recurrence has been noticed. In Ayurvedic surgery; Fistula has been categorized among eight diseases which are difficult to cure. A highly specific Ksharsutra procedure has been advised in Ayurvedic surgery to treat this problem. Subsequently, efficacy of this Ksharsutra therapy was compared with surgery in 1991. This clinical trial was conducted by Indian Council of Medical research at AIIMS New Delhi and PGI Chandigarh. They have clearly reported that Ksharsutra treatment is more convenient and more effective as compared to surgery in the patients of Anal fistula. The recent concept of Graded Ksharsutra has further improved the efficacy of this therapy. Facility of Graded KsharsutraTM is available only at Sushruta Ano rectal Institute Rohini; New Delhi. 

Ksharsutra Therapy: It is a highly specific and most effective amongst all available treatments for the patients of Anal Fistula. In this treatment; the first step consists of proper identification of fistulous tract with respect to depth, direction and branching pattern. This is usually achieved by careful probing or taking the help of MRI Fistulogram, Ultrasound etc. One the tract has been defined Ksharsutra is placed in the tract with the help of malleable probes under local anesthesia. Since there is no injury to the soft tissue hence no pain or bleeding is expected after this treatment. Patient can continue his routine activities as usual from the very first day. The Ksharsutra – medicated thread is changed at weekly interval. Usually the Fistula heals @ 0.5 to 1 cm per sitting. Therefore the anal fistula which is 4-6 cm long they usually heal in 8-10 sittings. After Ksharsutra Treatment the sphincter control remains normal and the fistula heals completely.
