About TOpCLASS Consortium

The TOpCLASS consortium is a large, international, group of perianal clinicians and/or researchers, which has developed following a project reclassifying Crohn’s anal fistula. The group includes gastroenterologists, colorectal surgeons, and GI radiologists who have active research output in the field of perianal Crohn’s disease or high-volume clinical practices in perianal disease care.

The group currently includes major centres across Europe, North America, Australia, and South America; however, is actively seeking to expand to encompass teams in Asia and Africa. Our aim is to create a global network of perianal Crohn’s disease research, cultivating collaborations and progressing global progress into this disabling form of inflammatory bowel disease.
