Short-term survival after surgery for epiploic foramen entrapment compared with other strangulating diseases of the small intestine in horses.

The research article describes a study conducted to compare the post-operative survival rates of horses suffering from Epiploic Foramen Entrapment (EFE), a common cause of colic, and other strangulating small intestinal conditions. The study concludes that horses with EFE have a better short-term survival prospect after surgical intervention as compared to horses with other strangulating intestinal diseases.

Methodology

• The study was based on the surgical records of 157 horses that underwent surgery for strangulating lesions of the small intestine at the University of Illinois between 1994 and 2003.
• The horses were categorized into three groups for comparison: those with EFE, strangulation caused by lipoma, and miscellaneous strangulating lesions.
• Multiple statistical models including logistic regression and Monte Carlo tests were applied to analyse the survival rates post-surgery, while measurements of length and viability indices were analysed using one-way analysis of variance.
• The study also included the use of Tukey’s HSD test and the exact Kruskal-Wallis test to analyse viability scores.

Findings

• The research revealed that horses operated for EFE had significantly higher survival rates (95%) after surgery than those with the other conditions, indicating a good prognosis for EFE.
• The study also noticed a greater proportion of ileal (part of the small intestine) involvement in horses with EFE as compared to the other two groups. However, this did not influence the outcome of the surgery.
• The distributions of the viability grades post-surgery for horses with EFE and lipoma differed significantly.

Conclusion

• In conclusion, the research shows that the post-operative prognosis for horses with EFE is better than those with other strangulating conditions of the small intestine.
• However, the high proportion of ileal involvement in horses with EFE requires careful consideration from surgeons, ultimately suggesting improvements in surgical techniques like jejunocaecostomy and critical decision-making about the viability of the bowel to avoid unnecessary procedures.
