Fistula in Ano
Fistula in Ano are classified as High and low fistula in Ano. The conventional method of management is surgical excision of the fistulous tract, but surgical management leads to lot of scarring and also recurrence is common.
The other unconventional methods are use of fibrin glue, fibrin plug, nectacryl ( cynaoacrylate glue) etc., but even with these the recurrence is common as it does not lead to satisfactory management of the primary pathology that is the diseased anal gland which led to the formation of the fistula in Ano.
This had led to resurgence in the interest in use of medicated seton (Kshara sutura) for use in the management of the Fistula in Ano. It leads to less scarring and does not require admission of the patient to the hospital. The treatment is done on OPD basis.
