Evaluation of enterolithiasis in equids: 900 cases (1973-1996).

The study investigates the impact of enterolithiasis, a condition characterized by the formation of stone-like structures in the gut, in equids such as horses over a 23-year period. The authors identify the demographics of equids susceptible to the condition, along with the common symptoms, treatment outcomes, and recurrence rate of enterolithiasis.

Research Methodology

• The study was retrospective in nature, analyzing medical records of 900 equids diagnosed with enterolithiasis between 1973 and 1996.
• The information collected from these records included demographic details (breed, age, sex), symptoms, physical examination findings, surgical reports, and outcomes after treatment.
• The researchers also conducted telephone interviews with the equids’ owners to gather more information.
• The prevalence of enterolithiasis among different breeds was determined by comparing the study population with the general hospital population of equids during the same time period.

Findings and Results

• Out of all the equids admitted for colic treatment, 15.1% were diagnosed with enterolithiasis, and 27.5% of equids that underwent celiotomy (abdominal surgery) for colic treatment had the condition.
• Certain breeds such as Arabian and Arabian crosses, Morgans, American Saddlebreds, and donkeys were more likely to develop enterolithiasis, whereas Thoroughbreds, Standardbreds, warmbloods, and stallions were less likely.
• The average age of diagnosis was 11.4 years.
• Common symptoms included intermittent colic (in 33.3% of cases) and passing of enteroliths in feces (in 13.5% of cases).
• Gastrointestinal tract rupture caused by an enterolith led to euthanasia in 15% (131) equids.
• Short-term and long-term (1-year) survival rates after surgery for enterolithiasis were promising at 96.2% and 92.5% respectively. Postoperative complications were rare.
• Recurrence of the condition was observed in 7.7% of the equids.

Conclusion

• The study concludes that equids, especially certain breeds, have an excellent short-term and long-term survival rate after surgical treatment for enterolithiasis and the condition’s recurrence is relatively low.
• By identifying certain patterns in demographics, symptoms, and other risk factors, equids at high risk of developing enterolithiasis can be identified and potentially treated proactively.
