Comparative analysis of racing performance following surgical correction of epiglottic entrapment in standardbreds and thoroughbreds.
Abstract: Epiglottic entrapment (EE) is a common cause of poor performance in racing standardbreds (STBs) and thoroughbreds (TBs). There is limited information published on the condition in STB racehorses and limited information on factors associated with return to racing available for either breed. Unassigned: This study investigated and compared the pre surgical findings, post-surgical complications and racing performance in STBs and TBs undergoing surgery for correction of EE. Associations between signalment and pre-surgical findings, and the presence of complications and racing post-surgery were compared using logistic regression analyses. Racing performance following surgery was compared to maternal siblings using conditional logistic regression. Unassigned: There were 82 cases where epiglottic entrapment surgery was performed at least once: 33 STB cases and 49 TB cases. In total, 74% of cases raced following surgery. Cases with severe inflammation post-surgery ( < 0.001), airway complications ( < 0.001) or an epiglottic re-entrapment ( < 0.01) were at a lower odds of racing post-surgery. TB cases were 5.5 times (95% Confidence interval 1.61 to 18.73) more likely to race than their maternal siblings ( < 0.01). TB cases took 79% longer to return to racing compared to STB cases ( < 0.001). Horses that had raced prior to surgery were 4.1 times more likely to race after surgery than those that had not (95% CI 1.01-16.67). Unassigned: Horses with post operative complications were at a lower odds of racing post surgery. In the current study, TBs with EE are more likely to race compared to their maternal half siblings however take longer to return to racing compared to STBs.

This research examines the effects of surgical correction of a common horse condition called epiglottic entrapment on the racing performance of two breeds of racehorses, standardbreds and thoroughbreds. The study investigates factors associated with return to racing and complications after surgery.
Research Purpose and Methodology
- The research sought to explore and contrast the pre and post-surgical findings, complications, and racing performance in standardbreds and thoroughbreds that had undergone surgery for the correction of Epiglottic Entrapment (EE). This was done due to scarce data about the condition in standardbred racehorses and the factors that determine their return to racing after surgery.
- To make these comparisons, the researchers used logistic regression analyses. This statistical method is used to model the probability of a certain class or event such as pass/fail, win/lose, etc., and offers quantitative analysis of the associated factors.
- Moreover, the researchers compared the post-surgery racing performance to that of maternal siblings using conditional logistic regression, thereby providing relative performance insights.
Findings and Observations
- The study analyzed 82 cases where horses underwent surgery for EE. There were notably more thoroughbred cases (49) than standardbred cases (33). It was found that 74% of the horses raced following their surgeries.
- Horses with severe inflammation post-surgery, airway complications, or a re-entrapment of the epiglottis had lower chances of racing post-surgery. This shows that post-operative complications significantly affect the ability of the horse to return to racing.
- Thoroughbred cases were 5.5 times more likely to race compared to their maternal siblings, thereby suggesting a positive effect of the surgery on their likelihood to race.
- However, it was also observed that thoroughbreds took 79% longer to return to racing compared to standardbreds, indicating variability in recovery times between the horse breeds.
- Horses that had already experienced racing before surgery were 4.1 times more likely to race post-surgery compared to those who had not, indicating the potential impact of prior racing experience on the recovery prognosis.
Conclusion
- The study found that horses with post-operative complications had lower chances to return to racing. In general, thoroughbreds with EE were more likely to race compared to their maternal half-siblings, but took comparatively more time to return to racing than standardbreds.
- This research provides valuable insights into the effectiveness and implications of surgical correction of EE and its impact on the subsequent racing performance of standardbreds and thoroughbreds.
