Modified York Mason Procedure for the Closure of a Complex Anterior Fistula in Ano.

The York Mason procedure was initially described for the management of recto-urinary fistulae. Although this procedure may be difficult to perform, success rates and long-term outcomes are encouraging. Adopting this technique for the management of a complex non-recto-urinary fistula in ano may be reasonable. In this manuscript, the York Mason technique was modified to repair a complex type 4 anterior fistula in ano without involvement of the urinary system with good results. [ABSTRACT FROM AUTHOR]
