Which histopathological scoring system was used?

• A. Banff criteria
• B. Sydney scoring
• C. NIH GI scoring
• D. WSAVA GI Standardization Group

Answer: (D)

In veterinary GI pathology, a standardized way to describe and quantify tissue changes is essential for consistency across cases and studies. The WSAVA GI Standardization Group established a consensus framework for evaluating canine and feline GI biopsy histopathology, providing structured criteria for inflammatory infiltrates and mucosal architectural changes. This system helps reduce observer variability and allows meaningful comparison of results between different clinicians and papers. The other options come from different fields: Banff criteria are used in transplant pathology, the Sydney scoring system was developed for human gastric/duodenal disease, and NIH GI scoring is a human inflammatory bowel disease framework. Therefore, the histopathological scoring system used is the WSAVA GI Standardization Group.
