Abnormal conditions of the equine descending (small) colon: 102 cases (1979-1989).

The research explores the distinct types and trends of descending colon disease in horses, considering factors like breed, age, and gender. The study observed that certain breeds, female horses, and older horses are more likely to succumb to these diseases, with specific conditions favouring certain age groups and genders.

Introduction

• The study reviews 102 cases of descending colon disease in horses over a period of 10 years (from 1979 to 1989).
• The research examines various factors like the breed, clinical and laboratory findings, types of surgical conditions, treatment, and outcomes.
• The descending colon diseases were categorised into eight types, including enteroliths, impactions, strangulating lipomas, fecaliths, foreign body obstruction, volvulus, nephrosplenic entrapment, and other conditions.

Breed findings

• Eleven different horse breeds were involved in the study, with Arabians, Ponies, and American miniature horses found to be more predisposed to diseases of the descending colon than the other breeds.
• Notably, Arabian, Quarter Horses, and Thoroughbreds greater than 10 years old were exceedingly represented compared to the hospital population.

Age and Gender Findings

• The research shows that female horses and horses older than 15 years are more likely to be affected with descending colon diseases, compared to horses that are less than 5 years old, which were less likely to be affected.
• Horses between the ages of 5 and 10 were most commonly affected by Enteroliths. This type of illness was not found in horses less than 2 years old and was more common in female Arabians.
• Impactions were more likely to affect horses older than 15 years and ponies and American miniature horses in particular. Additionally, female horses were more prone to impactions than males.
• Strangulating lipomas were prominently observed in horses older than 15 years and specifically in female Quarter Horses.
• Fecaliths were seen in horses less than 1 year old or horses greater than 15 years old, affecting males more often than females.

The Importance of this Study

• This study helps identify specific predispositions for various strains of descending colon diseases in horses. This can aid in prevention and early detection strategies, optimizing veterinary interventions.
• Knowing the risk factors such as breed, age, and gender can help horse owners and veterinarians to better manage and treat horses prone to descending colon diseases.
