Outcome of Modified Ligation of Intersphincteric Fistula Tract Procedure in Patients with Transsphincteric Anal Fistula.

Abstract

Introduction: Fistula in ano is a common anal disease that is problematic to both the patient and the surgeon.Various treatment modalities have been introduced to treat fistula in ano without compromising anal sphincterfunction.Aim of work: In our study we aim to assess the outcomes of modified Ligation of Intersphincteric fistula tract inpatients with transsphincteric fistula as one of the sphincter sparing modalities.Patients and methods: This is a cross sectional study that included 50 patients who were diagnosed withtranssphincteric fistula tract and treated with modified Ligation of Intersphincteric Fistula Tract. Patients withrecurrent fistula, perianal abscess, Crohn’s disease or any other perianal disease were excluded from our study.Results: The mean age of participants was 39.92 years and more than half of them were males (Males; n = 32while females; n = 18). The mean operative time was 30.30 ± 7.09 and mean healing time was 5.38 ± 1.31 weeks.No incontinence was observed throughout the follow up period (0%). Total of three patients had incomplete healingand persistent perianal discharge (6%) while four patients showed recurrence after complete healing (8%).Conclusion: The modified Ligation of Intersphincteric fistula tract technique is an effective sphincter-sparingprocedure that has shown lower incidence of recurrence without affecting anal continence.
