The first participating centres are now up and running, with data already collected from the first patients recruited to the study.

This marks an exciting milestone for CLARITY and reflects the commitment of collaborators around the world to answering an important question in the surgical management of ulcerative colitis.

CLARITY is designed to evaluate the role of therapeutic appendicectomy in patients with ulcerative colitis, generating high-quality international evidence through the ESCP federated research model.

We would like to thank all the centres that have already joined the study, and everyone involved in getting CLARITY off the ground. If your centre has not yet registered, there is still time to get involved.
