Summary
# Editorial Summary: Standing Laparoscopic Herniorrhaphy in Stallions Inguinal herniation in stallions traditionally requires general anaesthesia and often castration, creating significant welfare and breeding implications. Marién and colleagues evaluated standing laparoscopic repair using cylindrical polypropylene mesh in nine stallions, achieving adequate analgesia through detomidine sedation combined with local mepivacaine infiltration at three paralumbar fossa portal sites. The mesh was secured within the inguinal canal and underwent natural adhesion formation, resulting in complete canal obliteration within 2 weeks post-operatively. This minimally invasive approach preserves testicular function whilst avoiding the systemic risks and recovery complications associated with general anaesthesia—a meaningful advancement for valuable breeding animals requiring hernia repair. Farriers and stud managers should be aware that this technique offers an alternative to castration for herniated stallions, though the procedure's accessibility remains dependent on specialist equine surgical facilities and the surgeon's laparoscopic expertise.

Practical Takeaways
- •Standing laparoscopic herniorrhaphy offers a viable minimally invasive alternative to traditional open surgery for inguinal hernias in stallions, preserving fertility
- •Adequate analgesia using sedation and local infiltration enables the procedure to be performed without general anesthesia
- •Plan for 2-week recovery period for inguinal canal obliteration; monitor for adhesion formation as part of the healing mechanism
Key Findings
- •Standing laparoscopic herniorrhaphy was successfully performed in 9 stallions using detomidine sedation and local mepivacaine infiltration
- •A cylindrical polypropylene mesh was inserted via three portal sites at the paralumbar fossa and fixated in the inguinal canal
- •Adhesion formation obliterated the inguinal canal within 2 weeks post-operatively
- •The technique allowed testis-sparing herniorrhaphy in standing horses, minimizing invasiveness compared to traditional approaches
