Standardized GI Endoscopy Reporting Forms

The upper and lower GI endoscopy report forms linked below, represent the work of the WSAVA Working Group on GI Histopathology. The group recognized the need to also standardize endoscopic examination and sampling of the GI tract to ensure the highest procedural diagnostic yield. These endoscopy report forms help address this, namely that endoscopic examination is complete and thorough. Ongoing work is looking at the number of mucosal biopsies needed to ensure diagnosis of different lesions as well as the effect of quality of endoscopic biopsy on the likelihood of diagnosis. The GI Standardization Group hope that we will soon have standards of histological interpretation based upon an analysis of naturally occurring case clinical features.


  • These forms have been officially endorsed by the Comparative Gastroenterology Society (CGS) and the European Society of Comparative Gastroenterology (ESCG).
