Endoscopic appearance of gastric lesions in foals: 94 cases (1987-1988).

This research paper discusses the findings of a study that examined the prevalence and characteristics of gastric lesions in foals, using gastroendoscopy over a period of two years (1987-1988). The findings suggest a high occurrence of these lesions, particularly in foals of specific age ranges, and a correlation with clinical disorders.

Introduction and Methodology

• The study’s aim was to explore the behaviour and incidence of gastric lesions in foals. This was driven by the necessity for better understanding of gastric disorders in horses of a young age. The exploration was done through gastroendoscopy, an imaging technique used to visualize the horse’s stomach.
• The research spanned over two years, from 1987 to 1988, and involved 183 foals. These were divided into two age groups, 1-85 days old and 90-310 days old. This distinction was important as the researchers wanted to know if age affected the occurrence of gastric lesions.

Findings

• Of the total 183 foals examined, 94 were identified with gastric lesions. The division in age depicts a higher possibility of gastric lesions appearing in the younger set of foals (1-85 days old), while the older set (90-310 days) were less affected.
• Primarily, the study found that the lesions were most prevalent in the foals’ stratified squamous mucosal epithelium, especially near the margo plicatus, an area in the horse’s stomach. The gastric glandular mucosa, another zone in the stomach, also showed gastric lesions but with much less frequency.
• When the results were investigated to understand the association between gastric lesions and clinical disorders, the research showed that lesions in the gastric glandular mucosa occurred more frequently in foals diagnosed with a disease.

Conclusion

• In conclusion, the study revealed that young foals are more prone to developing gastric lesions, particularly in the stratified squamous mucosal epithelium around the margo plicatus section of the stomach.
• In addition, there was a strong correlation between the presence of gastric lesions and concurrent clinical disorders, particularly in foals older than 90 days. However, in younger foals, such lesions appeared with or without any associated clinical disorder.
• These findings provide valuable insights for veterinarians, allowing for better early detection and treatment plans specifically tailored according to the age and health conditions of the young equine patients.
