Brief Summary
This is a multicentre prospective international observational study. This study aims to introduce a novel multidimensional approach to precision imaging, enabling the identification and stratification of high-risk patients who can potentially benefit from early treatments to halt the progression of Crohn's disease (CD). The investigators will develop a novel endoscopic assessment system using endoscopic enhanced imaging (EEI) to evaluate early post-surgical changes and predict post-operative CD recurrence (POCr). By integrating with immune marker profiling, clinical data, and AI assessment of EEI and histology, the investigators further plan to improve risk stratification and reduce interobserver variability.

Outcome Measures
Primary Outcomes (2)
Early post-operative endoscopic recurrence
Post surgical endoscopic recurrence will be defined as Simple Endoscopic Score for Crohn's Disease (SES-CD) \> 2 and Rutgeerts score \> i2a
3 months or 6 months
Early post-operative clinical recurrence
Post surgical clinical recurrence will be defined as: * CD Activity Index score (CDAI) \>200 and a \>70-point increase from baseline, or * development of a new or re-draining fistula or abscess, or * requiring steroids, endoscopic dilatation, or hospitalization
3 months and 6 months
Secondary Outcomes (3)
Post-operative clinical recurrence
1 year and 2 years
Early post-operative histological recurrence
3 months or 6 months
Early post-operative IUS recurrence
3 months or 6 months
Study Arms (1)
Post-operative CD
Patients undergoing surgery or with a previous (within 3 months from the enrolment) surgery for CD
Interventions
The colonoscopy will be performed at 3 or 6 months after surgery according to FC: * In patients with FCP \>=150µg/g at around 3 months after surgery, a colonoscopy will be immediately performed * In patients with FCP \<150µg/g at around 3 months after surgery, the colonoscopy will be organized at 6 months after surgery Colonoscopy will be performed using high definition white-light endoscopy (HD-WLE) followed by virtual chromoendoscopy (VCE). The neoterminal ileum, ileocolic anastomosis and right colon will be assessed. A follow-up colonoscopy will be performed within 18 months after index colonoscopy, as standard of care.
During index colonoscopy, at least 2 biopsies from each of the segments will be taken as standard of practice to assess inflammation in post-operative CD. Only in Irish sites, twelve biopsies - four in the area of ileocolonic anastomosis, four in the neo-terminal ileum and four in the colon just distal to the anastomosis- will be taken for research purposes, in addition to standard-of-care biopsies.
pCLE with fluorescein injection will be performed during index colonoscopy, in centres where is available, to assess early alteration of the barrier function.
All patients will undergo a cross-sectional imaging test as part of their standard of care at 3 and 6 months after surgery. A follow-up IUS will be performed within 18 months after index colonoscopy, as standard of care.
Stool samples will be collected at 3 and 6 months after surgery and used for faecal calprotectin analysis. Research stool will be collected during the visit of index colonoscopy and at 12 months after index colonoscopy for metagenomics (only in Irish sites).
Blood will be collected at 3 and 6 months after surgery and used as standard of care. Research blood will be collected during the visit of index colonoscopy and at 12 months after index colonoscopy for research - i.e. proteomic, genomic, cell experiments (only in Irish sites).
Saliva will be collected during the visit of index colonoscopy and at 12 months after surgery for research - i.e. optical spectroscopy (only in Irish site)
Patients will be followed-up at 6, 12 and 24 months after index endoscopy. Patients will be evaluated in clinic or by telephone call and the disease will be reassessed. The following scores will be repeated: Harvey Bradshaw Index (HBI) and CD Activity Index score (CDAI). Participants will give an update on their medication use.
Eligibility Criteria
Males and females aged between 18 and 75 years old and with an established diagnosis of CD, who have undergone surgery no more than three months before study entry, or have surgery planned, will be consecutively recruited after obtaining written consent. The sample size for the study is 225
You may qualify if:
- Patients aged between 18 years and 75 years.
- Established diagnosis of CD at least six months prior to study.
- Patients who have undergone intestinal resection within 3 months before study entry or have surgery planned.
You may not qualify if:
- Inability to provide consent.
- Presence of serious co-morbidities (clinical contraindication).
- Presence of ostomy.
- Pregnancy or breastfeeding.
- Contraindication for colonoscopy or biopsies.
- Boston Bowel Preparation Scale Score \<2 in the rectum plus left-sided colon.
- Allergy to nuts or shellfish.
- Severe or uncontrolled asthma.
- Use of beta blockers.
- Previous history of reaction to fluorescein.
- Patients excluded from pCLE can still enter the study and undergo only standard-of-care endoscopy.
