Landmark publication from the TOpClass consortium

Landmark publication alert!

Huge congratulations to Luke Hanna, Liesbeth Munster, Shivani Joshi, Jarmila van der Bilt, Phil Tozer, and Ailsa Hart on this brilliant work from the TOpClass consortium

This article proposes the first-ever diagnostic criteria for isolated perianal Crohn’s disease (ipCD) — a condition that’s long been overlooked in clinical practice. These criteria represent a critical first step toward standardising diagnosis, improving earlier detection of IBD in fistula patients, and supporting future research to improve our understanding and management this condition.

A big step forward in the complex world of perianal disease and IBD. Well done to the whole team!
