Ponies, miniatures, and younger equids are at higher risk of fecalith obstruction compared to a general colic population.

The research article discusses the higher risk of fecalith obstruction in breeds such as ponies, miniatures, and young equids compared to the general colic population and investigates factors influencing the survival rates and prognosis after surgical treatment.

Methods

• The study involved a review of medical records of 151 equids who underwent surgery for fecalith obstruction between 2000 and 2020.
• Various factors including breed, age, sex, clinical history, clinicopathology data at presentation, surgical findings and complications, and short-term survival were all recorded. Data between survivors and non-survivors was then compared.
• The researchers also compared the fecalith population, or the population of equids with fecalith obstruction, to a contemporaneous colic population, or the population of equids with colic.
• Furthermore, they assessed any association between various clinical factors and outcome.

Results

• Data gathered from the review represented a diverse demographic, including 64 females, 53 castrated males, and 31 intact males.
• Nearly half (48%) of the fecalith population consisted of miniature horses, ponies, and miniature donkeys/mules, while the remaining 52% were full-sized breeds.
• The data revealed a high survival rate post-surgery, with 92% surviving to discharge. However, 6% were euthanized intraoperatively and another 2% were euthanized during hospitalization.
• Fecalith obstruction disproportionately affected miniature horses, ponies, and young equids when compared to the colic population.
• Non-survivors exhibited more severe colic signs upon admission, tachycardia, and hyperlipemia (an excess of fats or lipids in the blood).
• Equids experiencing colic post-surgery and surgical complications were less likely to survive.

Conclusions

• Despite overrepresentation in the fecalith population, miniature breeds and ponies have an excellent short-term prognosis following surgical treatment.
• The study highlighted several factors that negatively impact short-term survival including severe colic signs, tachycardia, hyperlipemia, postoperative colic, and surgical complications.

This research provides valuable insights into the predispositions, prognoses, and challenges confronted in the surgical treatment of fecalith obstruction in the equid population. The findings could potentially guide future clinical decision-making and interventional strategies.
