The 2026 Digestive Disease Week (DDW) is quickly approaching. From May 2 through May 5, in Chicago, Illinois, DDW is a major global gathering for gastrointestinal and hepatology professionals from around the world. With four days packed with informative sessions and ground-breaking research presentations, we’re taking the time to highlight sessions focusing on Crohn’s disease.

While there are many IBD sessions currently scheduled that focus on both ulcerative colitis and Crohn’s disease, and IBD in general, the following sessions focus on Crohn's disease. All times and dates are accurate as of March 25, 2026. View the complete Digestive Disease Week 2026 schedule for the full look at currently scheduled sessions.
