After abscess formation, an anal fistula is a common consequence, with crypto-glandular infection being the most commonly accepted causative cause. The goal of this study was to see how well closure of the inter-sphincteric fistula tract affects the outcome of trans-sphincteric fistula surgery. Patients with perianal trans-sphincteric fistulas who underwent ligation were studied prospectively. All patients had the identical anesthetic approach, followed by the operation with two years' follow-up.

The surgical treatment was achieved through identification of the fistula by injecting hydrogen peroxide (H2O2) through the external opening. Probing of the fistulous tract by a metallic probe for proper identification of the fistula in the inter-sphincteric plane. Perpendicular skin incision (about 1 cm) was done at inter-sphinctric zone, perpendicular to the fistulous tract. Dissection between the internal and external sphincters and identification of the fistula. Finally, Ligation and transection of the tract in inter-sphinctric space followed by excision of a segment and transferred for histopathology examination. Trans-fixation suture was applied near to the internal mucosal opening of the divided tract to confirm closure using polyglactin suture 2/0. Insertion of a probe to check the closure of the tract segments. The remaining part of the tract was curetted till external opening and left for spontaneous healing.
