Experience with staged mucosal advancement anoplasty for high trans-sphincteric fistula-in-ano.

Successful eradication of a complicated, recurrent fistula-in-ano with maintenance of anal continence, requires a specialized surgical approach. Mucosal advancement anoplasty is associated with acceptably low rates of recurrence and continence and is reported in this small series of 11 patients where it followed preliminary deployment of a loose guiding and drainage seton. The technique was also supplemented by internal anal sphincter repair at the time of the advancement anoplasty. Success was achieved in nine cases without any effect on reported continence.
