Consortium Members
The TOpClass consortium is an international collaboration that brings together world-class experts to advance understanding and management of perianal Crohn’s disease. Our research explores disease pathogenesis, classification of phenotypes, and how healing and outcomes can be measured more reliably across centres.
Bridging surgery, gastroenterology, radiology and translational science, we have developed practical, evidence-based tools that enhance patient care and bring greater consistency to research worldwide.
