Cohort study of fistulotomy with external tract fistulectomy and primary sphincter reconstruction in high trans-sphincteric fistula-in-ano.

Aim: Treatment of complex fistula-in-ano is challenging and there is no consensus on the optimal treatment that can provide complete healing and preserve sphincter function. The aim of this study was to evaluate fistulotomy with external tract fistulectomy and primary sphincter reconstruction (FFSR) in the treatment of high trans-sphincteric fistula.

Method: This is a prospective single-centre study including patients with a high trans-sphincteric fistula who underwent FFSR from June 2017 to June 2018.
