Summary
# Editorial Summary: Inguinal Approach to Equine Castration Post-operative complications following equine castration carry significant clinical and economic implications, prompting investigation into refined surgical techniques. Kummer and colleagues evaluated a novel inguinal approach in 238 mature stallions castrated under general anaesthesia, where the vaginal process was incised, the spermatic cord ligated twice, and closure was achieved in layers through the vaginal tunic, fascia, subcutis and skin in simple continuous pattern. Surgical site complications were notably low: haemorrhage and scrotal haematoma occurred in 2.1% of cases (all resolving fully), whilst respiratory infection and transient post-operative colic were recorded in 2.1% and 8.8% of horses respectively, with all cases responding to conservative management. The inguinal approach appears advantageous compared with traditional scrotal methods, likely because leaving the vaginal tunic intact and avoiding extensive scrotal incision minimises soft tissue trauma and associated morbidity. For equine practitioners, this technique merits consideration as a refined castration protocol, particularly for mature stallions where minimising post-operative complications and recovery time has direct implications for return to work and client satisfaction.

Practical Takeaways
- •The inguinal castration technique offers a safer option with lower complication rates at the surgical site compared to traditional scrotal approaches
- •Expect post-operative respiratory infections and colic in approximately 2-9% of cases; monitor accordingly and have antibiotic protocols ready
- •Leaving the vaginal tunic intact appears to reduce tissue trauma, potentially contributing to the lower complication rate with this approach
Key Findings
- •Inguinal approach castration resulted in 2.1% (5/238) post-operative haemorrhage and haematoma requiring additional treatment
- •Post-operative respiratory infection occurred in 2.1% (5/238) of cases, all resolved with antibiotics
- •Transient colic signs occurred in 8.8% (16/238) of horses after surgery
- •Inguinal approach with vaginal tunic left in situ produced lower surgical site complications compared to scrotal approach methods
