Causes of gastrointestinal colic in horses in western Canada: 604 cases (1992 to 2002).
- Journal Article
Summary
The given research article provides a review of the medical records from 1992 to 2002 related to cases of gastrointestinal colic in horses. The study was conducted at the Western College of Veterinary Medicine in western Canada. It was found that geldings were more prone to this condition. The predominant causes of colic were large colon impaction, large colon displacement, and spasmodic colic, with recovery rates aligning with those from other studies.
Overview of the Study
The study was based on the review of medical records of horses suffering from gastrointestinal colic presented to the Western College of Veterinary Medicine between 1992 and 2002. The study aimed at an in-depth understanding of the causes leading to this condition, the predisposition of breeds, gender biases, and the recovery rates of the affected horses.
- The data didn’t show any specific breed that was more prone to colic.
- It was identified that geldings (castrated male horses) were more prone to colic as compared to females and stallions (intact male horses).
Causes of Colic in Horses
Three main causes of colic were noted:
- Large colon impaction, which was observed in 20.8% of the cases. It is a condition where the fecal matter forms a blockage in the horse’s colon.
- Large colon displacement, seen in 16.5% of the cases. In this condition, a portion of the horse’s colon changes or moves from its normal anatomical position.
- Spasmodic colic was the cause in 11.7% of studied cases. Spasmodic colic or ‘gas colic‘ involves painful spasms of the horse’s colon, usually due to an accumulation of gas.
These conclusions were drawn after excluding the 13% of cases in which the diagnosis remained undetermined.
Breakdown of Medical and Surgical Cases
The study also looked specifically at the medical and surgical cases:
- In medical cases, large colon impaction was the most common condition, again seen in 38.4% of cases, followed by spasmodic colic at 22.5%.
- In surgical cases, large colon displacement was the common cause affecting 24.5% of cases. Other conditions included large colon torsion (twisting of the large colon) and strangulating lipoma (a fatty tumor causing interruption of blood supply), which were observed in 14.3% and 13.5% of the cases respectively.
Recovery Rates
The recovery rates for both types of cases were found to be quite high:
- The recovery rate for the medical cases was high, reaching up to 93.6%.
- The recovery rate for surgical cases, while lower, was still substantial at 73.5%.
Conclusion
The study concluded that a majority of equine colic cases were medical in nature, and the recovery rates for both surgical and medical cases were comparable with those of other studies. This helps in the understanding of the condition and can aid in future approaches to treatment and management.
