Treatment of Rectovaginal Fistula with Anal Sphincter Defect (Obstetrical or Cryptoglandular Cause)

This protocol addresses patients with a rectovaginal fistula arising from an obstetrical or cryptoglandular cause who also present with a concurrent anal sphincter defect — a specific anatomical context that directly determines the surgical approach to repair.

Repair in this setting relies on a transperineal surgical technique that addresses both the fistula and the associated sphincter anatomy. The precise extent of the procedure and the structures involved are outlined in the full structured protocol.

The clinical goal is healing of the rectovaginal fistula.
