The effectiveness of the ligation of intersphincteric fistula tract technique in the treatment of simple trans-sphincteric anal fistula

Authors

Abstract

Background
The best cure for anal fistula, while maintaining the anal sphincter complex and complete continence, should remove inflammation and facilitate healing of the tract. The primary cure for anal fistula is surgery. There have been several surgical techniques mentioned. Intersphincteric fistula tract [ligation of the intersphincteric fistula tract (LIFT)] ligation, with the benefit of reducing anal incontinence, is a novel surgical technique. The low probability of an impaired sphincter function is one of the key benefits of the procedure.
Aim
To analyze the success rate of LIFT for patients with anal fistulas.
Patients and methods
From December 2017 to June 2019, 20 patients were added to this longitudinal study. Patients were treated with intersphincteric fistula (LIFT) technique, and effects were observed and reported, including recurrence rate, incontinence rate, and other postoperative complications. A follow-up cycle of up to 12 months has been completed.
Results
A total of 20 patients have been examined. The mean operation time was 39 min (range, 25–55 min), and there were no intraoperative complications. The average full healing rate was 90% and the recurrence rate was 10%. No patients have experienced incontinence.
Conclusions
LIFT technique is an effective method in the treatment of anal fistula with reduced risk of recurrence and anal incontinence.
