Recent advances in equine abdominal surgery.

The research article discusses recent advancements in the field of equine abdominal surgery, primarily focusing on the role of laparoscopy, stapling equipment, procedures to lessen adhesion formation, post-surgery treatments like administration of prokinetic agents and cyclooxygenase inhibitors, and methods improving incision healing in horses.

Laparoscopy in Equine Surgery

• The paper talks about the increasing use of laparoscopy for various surgical procedures in horses. It’s a minimally invasive method that can serve diagnostic, therapeutic, and prognostic purposes. The specific applications mentioned include ovariectomy, cryptorchidectomy, adhesiolysis, and herniorrhaphy.
• Specialized equipment is essential for effective laparoscopy. The position, whether standing or dorsally recumbent, depends on factors like surgeon preference, patient status, and the nature of the surgical procedure.

Use of Stapling Equipment

• The equipment used for stapling is emphasized as a key tool in gastrointestinal surgery in horses. Advantages mentioned include reduction in surgical time and a decreased risk of contamination.
• Stapling tools are often deployed in creating anastomoses in the large and small intestines and for vessel ligation.

Preventing Adhesion Formation

• The paper also discusses the introduction of new surgical techniques meant to minimize adhesion formation. The use of carboxymethylcellulose and bioresorbable patches have been mentioned specifically.
• Another technique noted is the use of indwelling abdominal drains for peritoneal lavage post-surgery, which also seems to lower the risk of adhesion formation.

Post-Surgery Treatments and Care

• The research stresses the importance of proper post-operative care, particularly in treating post-surgery ileus (intestinal obstruction) and endotoxaemia, a condition caused by presence of endotoxins in the horse’s blood. Enhanced post-operative care can significantly improve surgery outcomes for horses suffering from abdominal disorders.
• Various prokinetic agents such as local anaesthetics, macrolide antimicrobials, cholinergic agonists, and dopamine antagonists are cited for use in horses with ileus, despite differing opinions about their use.
• The antibiotic, polymyxin B, which binds to and decreases the half-life of the circulating endotoxin molecule, thereby lessening inflammation, has been termed an affordable and effective treatment for horses suffering from endotoxaemia post surgery.

Cyclooxygenase Inhibitors and Incision Healing

• The article refers to a new area of veterinary research focusing on the use of selective cyclooxygenase-2 inhibitors, which are thought to have similar anti-inflammatory and analgesic properties to non-selective non-steroidal anti-inflammatory drugs.
• Research also highlights the vital role of proper suture patterns, bite sizes, and appropriate post-operation exercise in the optimal healing of ventral midline incisions in horses.

Summary

• Overall, the article suggests that these innovations in surgical techniques and post-operative care could reduce the morbidity and mortality associated with abdominal surgery in horses.
