Summary
# Editorial Summary: Recent Advances in Equine Abdominal Surgery Equine abdominal surgery carries significant post-operative risk, with adhesion formation and complications such as ileus and endotoxaemia substantially affecting survival rates and long-term performance. Smith, Dowling and Dart's 2005 review synthesises contemporary surgical and medical management innovations, examining laparoscopic techniques (including ovariectomy, cryptorchidectomy and adhesiolysis), intraoperative stapling for intestinal anastomoses, and pharmacological strategies for post-operative support. Key advances include the use of carboxymethylcellulose and bioresorbable patches to minimise adhesions, indwelling peritoneal drains for lavage, prokinetic agents targeting multiple pathways (local anaesthetics, macrolides, cholinergic agonists and dopamine antagonists), and polymyxin B for managing endotoxaemia by reducing circulating endotoxin half-life. For practitioners managing post-surgical patients, these findings underscore the importance of tailored post-operative protocols: careful attention to incision closure technique (suture pattern, bite size and exercise management), judicious use of selective COX-2 inhibitors for analgesia with fewer gastrointestinal side effects, and appropriate antimicrobial and prokinetic selection according to the individual case presentation. Collectively, these technical and medical refinements meaningfully reduce morbidity and mortality in horses recovering from abdominal surgery, making their integration into practice protocols essential for optimising outcomes.

Practical Takeaways
- •Minimally invasive laparoscopic approaches can be offered as alternatives to traditional open surgery for various abdominal conditions, reducing recovery time and complications.
- •Post-operative management significantly impacts outcomes; consider using prokinetic agents for ileus prevention, polymyxin B for endotoxaemia, and adhesion-prevention strategies such as peritoneal lavage with indwelling drains.
- •Modern surgical materials and techniques including stapling devices and selective COX-2 inhibitors can improve safety and reduce complications in abdominal surgery cases.
Key Findings
- •Laparoscopy is effective for diagnostic, therapeutic and prognostic applications in equine abdominal surgery including ovariectomy, cryptorchidectomy, and adhesiolysis.
- •Stapling equipment in gastrointestinal surgery reduces operative time and contamination risk compared to traditional techniques.
- •Carboxymethylcellulose and bioresorbable patches along with indwelling abdominal drains effectively reduce post-operative adhesion formation.
- •Polymyxin B is an effective and affordable treatment for post-operative endotoxaemia by binding circulating endotoxin and reducing inflammation.
- •Selective cyclooxygenase-2 inhibitors provide comparable anti-inflammatory and analgesic effects to non-selective NSAIDs with potentially fewer side effects.
