The European Crohn's and Colitis Organisation (ECCO), founded in 2001 to improve the care of patients with inflammatory bowel disease (IBD) in Europe, is now the largest forum for specialists in IBD in the world. It is a non-profit association, which successfully expanded from an organisation comprising 14 Country Members to an association assembling 36 member states of the Council of Europe and facilitating collaborations beyond Europe's borders. You can find more info here: https://www.ecco-ibd.eu/
