Inside-Out Continuous Suturing Technique for the Repair of Third-Degree Perineal Laceration in Mares

Seven mares with third-degree perineal laceration were treated by a two-stage surgical technique. The rectovestibular shelf was corrected with two layers of inside-out continuous suture technique distributed along the longitudinal axis of the vestibule, vagina, and rectum simultaneously obliterating perivestibular and perirectal space with poly-p-dioxanone. Perineal body was reconstructed in the second stage with simple continuous pattern and the skin using a horizontal mattress suture pattern. All mares completed the two-stage surgery, and healing occurred in all of them. Three mares had foaled once without any subsequent injury, one mare was in foal, and others were in regular heat. The results of the present study indicate that the inside-out continuous suturing technique appeared to be effective for repair of third-degree perineal laceration.
