Objectives:
In brachycephalic dogs (BD), the respiratory obstruction resulting from brachycephalic obstructive airway syndrome (BOAS) can affect the gastrointestinal tract. The clinical signs of such gastrointestinal effects include vomiting, regurgitation, sialorrhea, dysphagia, hiatal hernia, gastritis, enteritis, and gastroesophageal reflux. This study aimed to provide quantitative data on the echogenicity of the stomach, duodenum, and jejunum in dogs with brachycephalic syndrome, correlating these values with the degree of BOAS, haematological changes, and systemic inflammation signs.
Methods:
Fifty-two BD and 15 mesocephalic controls aged between 1 and 8 years were selected for this study. Hemograms, biochemical analyses, C-reactive protein (CRP) analysis, and B-mode ultrasonography of the gastrointestinal tract were performed in all patients, and were followed by quantitative analyses of the images. BD were classified according to the presence of BOAS. In the quantitative analysis, eight regions of interest were defined in the mucosal layer of the stomach, duodenum, and jejunum, and the mean pixel values were quantified for each structure.
Results:
Brachycephalic patients showed significantly higher echogenicity in the duodenum and jejunum (duodenum: 18.2 ± 11.3 pixels; jejunum: 25.6 ± 15.2 pixels) than mesocephalic dogs (duodenum: 11.04 ± 4.3 pixels; jejunum: 9 ± 7 pixels). Furthermore, the groups of affected dogs showed notable differences. Gastrointestinal wall thickness remained within normal limits and showed no statistical difference. BD showed elevated CRP levels and leukocyte counts, along with a high prevalence of gastrointestinal signs such as diarrhoea, indicating subacute intestinal inflammation.
Conclusions:
Quantitative ultrasonographic evaluation yielded more reliable data on echogenicity, minimising examination subjectivity.
