Ultrasonographic findings in horses with right dorsal colitis: five cases (2000-2001).
Abstract: To determine whether ultrasonography would be useful in the diagnosis of right dorsal colitis in horses. Methods: Retrospective study. Methods: 5 horses with right dorsal colitis and 15 healthy adult horses. Methods: Mural thickness and appearance of the right dorsal colon were determined from ultrasonographic images obtained at right intercostal spaces 10, 11, 12, 13, and 14. Results: The right dorsal colon could be imaged most consistently at the right 11th, 12th, and 13th intercostal spaces, below the margin of the lung and axial to the liver. Mural thickness measured from ultrasonographic images was significantly greater in horses with right dorsal colitis than in healthy horses. The right dorsal colon in affected horses had a prominent hypoechoic layer associated with submucosal edema and inflammatory infiltrates. Successful treatment of 1 horse with right dorsal colitis was associated with a decrease in mural thickness coincident with an increase in serum albumin and total protein concentrations and weight gain. A decrease in mural thickness was also observed in a second horse treated for right dorsal colitis that was not associated with healing of the right dorsal colon or an increase in serum albumin concentration but rather thinning of a segment of the right dorsal colon that eventually ruptured. Conclusions: Results suggest that ultrasonographic measurement of mural thickness and evaluation of the appearance of the right dorsal colon may be useful in the diagnosis of right dorsal colitis in horses.

The paper is investigating the effectiveness of using ultrasonography to diagnose right dorsal colitis in horses. The researchers found that ultrasonography consistently provided images of the right dorsal colon and indicated increased tissue thickness in horses with colitis compared to healthy horses.
Methods
- The study was retrospective in nature and used ultrasonography to trace and examine the right dorsal colon of the horses.
- A total of 20 horses were involved in this study; 5 were affected by right dorsal colitis and 15 were healthy adult horses. These healthy horses served as a control group.
- The researchers focused on the mural thickness and the appearance of the right dorsal colon as their primary variables. They obtained these variables from the ultrasonographic images the program captured.
Results
- According to the ultrasonographic images, the right dorsal colon could be most consistently viewed at the 11th, 12th, and 13th right intercostal spaces, below the margin of the lung and axial to the liver.
- The study found significant differences between the mural thickness of horses suffering from right dorsal colitis and the healthy ones. It was notably greater in horses with the condition.
- For horses with right dorsal colitis, a prominent hypoechoic layer was observed. This was associated with submucosal edema and inflammatory infiltrates.
- Successful treatment of one horse with right dorsal colitis led to a decrease in mural thickness. This was alongside an increase in the concentration of serum albumin and total protein and weight gain.
- For a second horse treated for right dorsal colitis, a decrease in mural thickness was observed as well but was not linked to the healing of the dorsal colon or an increase in serum albumin. Instead, it was found in relation to the thinning of a segment of the dorsal colon, which eventually ruptured.
Conclusions
- The results obtained from the study indicate that ultrasonographic measurement of mural thickness and evaluation of the right dorsal colon’s appearance could be useful methodologies for diagnosing right dorsal colitis in horses.
