Evaluation of Modified Surgical Technique in Repair of Third-Grade Perineal Lacerations in Mare

Objective- introduce and evaluate modified surgical technique in repair of third grade perinea lacerations in mares. Design- descriptive study. Animals- ten mares. Procedures- The tissue between rectal and vagina mucosa was incised in the way that the lower rectal mucosa was entirely separated from upper vaginal mucosa and a flap was consequently induced in both sides. The septum between rectum and vagina was sutured by a six bite pattern at the same time with simple interrupted suturing of rectal mucosa using ۰ vicryl. The skin of the perineal body was closed with ۱ or ۲ absorbable or nonabsorbabale suture material in a horizontal mattress pattern. Results- The observations of surgical region during a month after surgery demonstrated that there were no signs of complete dehiscence, partial dehiscence and rectovestibular fistula. and primary healing had effectively occurred. Conclusion and Clinical Relevance- As the lesion recovered completely and there were no signs of fistula, rectal stenosis and reversion to pneumovagina, it is advisable to use this modified method for laceration.
