A one-stage repair of third-degree perineal lacerations and rectovestibular fistulae in 17 mares.

The research focuses on the one-stage surgical procedure to repair third-degree perineal lacerations and rectovestibular fistulae in 17 mares, revealing it a successful operation for most, leading to future healthy pregnancies.

Overview of the Study

• The study involves the research on a one-stage surgical repair method meant to treat serious perineal lacerations and rectovestibular fistulae in mares.
• Out of 17 mares that underwent the one-stage surgical repair, 14 experienced primary recovery or complete healing.
• While, there were minor complications in three mares, with one complete dehiscence (wound separation) and two partial separations accompanied by fistula formation.

Post-Surgical Observations and Results

• Post-operation, 13 out of 17 mares were bred successfully for pregnancy, demonstrating the success of the procedure in preserving or restoring mare fertility.
• Of these 13 mares, 9 foaled successfully and two are still in the gestation period.
• However, two gave birth to underdeveloped foals, and one of the mares consistently miscarried within the first trimester following the procedure.
• In spite of these complications, four of the mares were able to give birth to several healthy foals subsequently, indicating the procedure’s long-term success in restoring healthy fertility.
• Only one mare encountered further perineal trauma during foaling, suggesting that surgery does not entirely eliminate the risk of re-injury in some cases.

Conclusion

• This one-stage surgical repair procedure proves effective for most mares in treating severe perineal lacerations and rectovestibular fistulae, with the majority showing healing and capability to achieve successful pregnancy post-operation.
• However, some minor complications and variations in post-surgical fertility outcomes highlight the need for further investigation to optimize and improve the results of this procedure.
