Transendoscopic correction of epiglottic entrapment with a silicone-covered laser guide and diode laser in 29 horses.

This research paper reports on the successful use of a silicone-covered laser guide and diode laser for surgical correction of epiglottic entrapment in horses, a common condition that can affect their racing performance.

Methods of the study

• At the center of the study are Thoroughbred and Standardbred racehorses (29 in number) that had been diagnosed with epiglottic entrapment.
• The researchers introduced a silicone-covered laser guide endoscopically. The role of the guide included directing the diode laser’s cutting action while the entrapping subepiglottic membrane was being cut. In addition, the guide acted as a physical shield between the membrane and the epiglottic cartilage.
• Postoperative complications were recorded and trainer satisfaction was gathered using a follow-up questionnaire. Furthermore, race records were reviewed to examine any differences in the number of starts, wins, or earnings before and after the surgery.

Results from the study

• The entrapping membrane was successfully released in all horses involved in the study.
• The researchers observed mild postoperative complications such as surgical site swelling (in 12 horses) and coughing or mild nasal discharge (in 5 horses) during the first few days after the surgery.
• A significant percentage of trainers (96%) were satisfied with the outcome of the procedure. It is important to note that 93% of the horses were able to return to racing.

Conclusions drawn from the study

• The study established that using a laser guide to aid in the transection of the subepiglottic membrane can correct epiglottic entrapment in standing horses.
• The researchers highlighted factors such as ease of surgical technique, mild postoperative complications, and a good prognosis to return horses to racing as key reasons why this method is a suitable alternative to the traditional laser procedure.
