A portion of patients with Inflammatory bowel disease often require surgical intervention since they do not respond to the current therapies. Besides this risk, patients may develop post-operative disease complications, and the factors beneath are far from being understood or predicted. The investigators hypothesize that some priming factors remain in the resection margin after surgery and act as a memory of the evolution of the disease, leading to the recurrence or complications. The following proposals are made: 1. defining and validating in humanized experimental models of intestinal inflammation the spatial and temporal dynamics of the postoperative complications-priming factors 2. integrating them into a machine-learning-driven model to determine risk indices of disease recurrence in IBD patients. This risk prediction model will not change the clinical decision-making process but will only be built for research. Consequently, patients enrolled in this study will be monitored and treated as per the standard of care. This project will reveal possible causes and build methods predictive of postoperative complications ultimately resulting in changes in clinical management in the near future.

IRCCS Ospedale San Raffaele
Milan, Italy, Italy
RECRUITINGTo define spatial, cellular, and molecular characteristics of IBD-derived intestinal samples
To define the spatial transcriptome of UC and CD-derived intestinal mucosa, IBD-derived tissues will be analized by spatial transcriptomics, either at molecular or at microbiota level on formalin-fixed paraffin-embedded (FFPE) tissues stored at our pathology unit.
Time frame: 6 months from surgery
To build the predictive model of postoperative complications based on spatially and temporally resolved IBD characteristics
Other variables to be considered are CD4+ T-cells from the processing of blood
Time frame: 6-12 months from surgery
To determine the mechanism underlying post-operative complications by exploiting in-vivo (mouse) experimental models of intestinal inflammation.
At the time of surgery, feces will be collected from patients. The microbial component from the IBD surgical specimens will be isolated and injected into humanized animal models.
Time frame: 19-24 months from surgery
