Plain-English summary
This report discusses the importance of having clear guidelines for diagnosing inflammation in the stomach and intestines of dogs and cats using samples taken during endoscopy (a procedure where a camera is inserted to look inside the body). Until now, it has been hard for veterinarians to agree on what to look for in these samples, which makes it tough to compare different studies. A group called the World Small Animal Veterinary Association has created a set of standards that includes pictures and descriptions of the main changes seen in inflamed tissues. They also suggest a way to report findings from these samples consistently. The hope is that these standards will help veterinarians better understand and treat gastrointestinal diseases in pets and improve research across different animals.
Abstract
The characterization of inflammatory change in endoscopic biopsy samples of the gastrointestinal mucosa is an increasingly important component in the diagnosis and management of canine and feline gastrointestinal disease. Interpretation has hitherto been limited by the lack of standard criteria that define morphological and inflammatory features, and the absence of such standardization has made it difficult, if not impossible, to compare results of retrospective or prospective studies. The World Small Animal Veterinary Association (WSAVA) Gastrointestinal Standardization Group was established, in part, to develop endoscopic and microscopical standards in small animal gastroenterology. This monograph presents a standardized pictorial and textual template of the major histopathological changes that occur in inflammatory disease of the canine and feline gastric body, gastric antrum, duodenum and colon. Additionally, a series of standard histopathological reporting forms is proposed, to encourage evaluation of biopsy samples in a systematic fashion. The Standardization Group believes that the international acceptance of these standard templates will advance the study of gastrointestinal disease in individual small companion animals as well as investigations that compare populations of animals.
