P097 Spatially resolved insights into fistulating Crohn’s disease pathogenesis: Unveiling molecular heterogeneity

Crohn’s disease (CD) frequently results in fistula development in approximately 40% of patients due to sustained, transmural inflammation within the bowel wall. Despite advanced treatments, recurrence of fistulae affects one third of patients. Understanding its pathogenesis is crucial for targeted treatments, yet remains poorly defined. This study employs spatial transcriptomic and single-cell RNA-sequencing (scRNA-seq) technologies to characterise human fistulating CD tissue pathology.
