Summary
# Editorial Summary: Standing Laparoscopic Peritoneal Flap Hernioplasty for Stallion Inguinal Hernias Acquired strangulating inguinal hernia represents a significant surgical emergency in stallions, and recurrence remains a persistent clinical challenge when attempting to preserve breeding function. Wilderjans and colleagues assessed a standing laparoscopic approach using peritoneal flap hernioplasty (PFH) to reinforce the vaginal ring in 30 stallions with prior inguinal herniation, employing three laparoscopic portals to create an inverted U-shaped peritoneal flap that was reflected caudally over the vaginal ring and secured with laparoscopic staples. A critical finding emerged from their experience: whilst incomplete ring closure (covering only the cranial and middle third) resulted in recurrence in 4 of 11 stallions, complete coverage of the entire vaginal ring, crucially including the caudal aspect, prevented recurrence entirely in the subsequent 19 cases. The technique offered additional benefits of minimal morbidity, excellent cosmetic outcomes, and preserved breeding soundness in all stallions, with no apparent impact on subsequent fertility. For practitioners managing stallions with recurrent or high-risk inguinal herniation, this technique represents a valuable standing surgical option, provided the surgical strategy prioritises complete three-dimensional obliteration of the vaginal ring rather than partial reconstruction.

Practical Takeaways
- •Complete closure of the entire vaginal ring, particularly the caudal aspect, is essential—incomplete coverage resulted in 36% recurrence rate
- •Standing laparoscopic approach allows stallions to avoid castration and maintain breeding soundness while effectively preventing hernia recurrence
- •This technique should be considered for stallions with previous inguinal hernia as it offers superior cosmetic outcomes and lower recurrence than traditional approaches
Key Findings
- •SIH recurrence occurred in 4 of 11 stallions (36%) with incomplete vaginal ring closure versus 0 of 19 stallions (0%) with complete closure
- •Standing laparoscopic peritoneal flap hernioplasty is technically feasible with excellent cosmetic outcomes and no major complications
- •Complete coverage of the entire vaginal ring including the caudal aspect is critical to prevent recurrence
- •Breeding function was preserved in all stallions post-operatively with no apparent effect on fertility
