Abstract

BackgroundAfter 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. MethodsPatients with perianal trans-sphincteric fistulas who underwent ligation of inter-sphincteric fistula tract (LIFT) were studied prospectively in this cohort study. All patients had the identical anesthetic approach, followed by LIFT with two years’ follow-up. Resultslength of the fistulous tract had a substantial effect on the result. The presence of piles with fistula among the studied patients has no effect on the outcome. Mean operative time was 36.2 min and post operative pain was mild in most patients and concomitant anal fissure or piles has no effect on final result of LIFT procedure The mean time for wound healing was four weeks. Three patients had hidradenitis suppurativa and no any unusual histopathology results shown in the excised parts. ConclusionLIFT was an effective and straightforward sphincter-preserving technique in treating simple trans-sphincteric anal fistulas with excellent long-term control of trans-sphincteric fistula. More similar studies with a large number of patients are still needed to assess this surgical technique for trans-sphincteric fistula.
