AbstractBackground: The Sydney system for assessing infammatory lesions in the gastric mucosa is based on endoscopic and histological examinations. This study aimed to apply the Sydney system to diagnose gastritis in dogs. The study also compared the results of endoscopic and histological examinations conducted on gastric mucosal biopsy speci‑ mens. A total of 56 dogs with chronic vomiting were analyzed in the study. The physical appearance of the gastric mucosa was assessed through endoscopic examination, while the severity of the gastric infammation, infammation activity, glandular atrophy, and intestinal metaplasia were assessed by histopathological examination. Results: The endoscopic examination confrmed the presence of infammatory lesions afecting the gastric corpus and pylorus in all the dogs, although the severity of these lesions difered between the individuals. Refux gastritis was the most commonly observed gastric infammation. In the histopathological examination of the gastric mucosal samples, infammatory lesions were found in the gastric corpus of 53 dogs, while 55 dogs had lesions in the pylorus. This corresponds to a 96.4% agreement between the methods. Conclusions: The Sydney system is a useful tool for macroscopic and microscopic assessment of changes in the gastric mucosa as it enables the determination of infammation type and severity, which helps the canine gastroen‑ terologists to reliably compare the results of the tests performed in diferent facilities. Besides, the use of the Sydney system in diagnosing lesions facilitates the selection and efective monitoring of treatment. However, despite a high rate of agreement between the results of endoscopic and histopathological examinations, it is recommended to use both these methods for the assessment of the gastric mucosa in dogs.
