Introduction: Treatment of anal fistula is surgical. Seton has been in use for fistula treatment for many years. In this study we have used cutting Seton along with partial excision of the fistula tract for treatment of high type fistula. Material and Methods: 30 cases of trans-sphincteric high type anal fistula were treated by partial excision of fistula tract and use of cutting Seton. Patients were followed up for 6 months after treatment. Population characteristics, treatment received and follow-up data was analyzed. Discussion and Conclusion: Most patients were male. Posterior fistula was more common than the anterior one. Postoperative complications were minor and managed conservatively. No case of recurrence or fecal incontinence was seen on follow-up. Treatment by partial excision of fistula tract and cutting Seton produces satisfactory results.
