Transrectal ultrasonography of the caudal portion of abdominal and pelvic cavities in horses.

The research explores the use of transrectal ultrasonography in horses, using a 5-MHz transducer, to study the structures in the lower parts of the abdomen and pelvic cavities. The study found that this method provided useful diagnostic information about the horses’ health.

Research Design and Methodology

• The research utilised a 5-MHz transducer to perform transrectal ultrasonography on 12 horses.
• The subjects were divided into two groups: 8 healthy horses, used to establish a base understanding of the structures imaged by this technique, and 4 horses showing signs of intrapelvic or intra-abdominal disease, used to evaluate the diagnostic potential of the technique.
• The organs and structures imaged through this technique included left kidney, spleen, urinary bladder, urethra, accessory sex organs in male horses, portions of the intestinal tract, caudal part of the aorta, iliac arteries, and the cranial mesenteric artery in smaller horses.

Results

• The study concluded that transrectal ultrasonography was able to provide potentially valuable diagnostic information about health conditions in horses.
• The technique was particularly useful in visualising and diagnosing issues related to intrapelvic or intra-abdominal diseases.
• It appears that it provides detailed views of structures that are typically accessible through transrectal palpation, thereby enhancing the quality and precision of clinical investigations.

Implications and Applications of the Study

• This research is significant as it demonstrates the potential of using transrectal ultrasonography as a non-invasive diagnostic tool in equine medicine. Specifically it can be used to correctly diagnose intrapelvic or intra-abdominal diseases in horses, which could lead to more efficient and effective treatment strategies.
• While the sample size is relatively small, the study provides an important basis and encourages further research in this area to validate and extend these findings.
