The primary aim of the study is to investigate if IUS (as measured by B-mode and CDS) in combination with faecal calprotectin at 3 months after ICR is an early surrogate marker of endoscopic disease recurrence (as defined by a RS ≥ i2) at 6 months

简要总结

Crohn's disease (CD) is an inflammatory bowel disease causing chronic transmural inflammation followed by intestinal complications including strictures and penetrating lesions such as fistulas and abscesses. 30-50% of the CD patients will require surgery during the course of their disease. Unfortunately, resection is not curative and endoscopically recurrent lesions (i.e. endoscopic recurrence) are observed in 65-90% of patients within 12 months, and in 80-100% within 3 years after the operation. Eventually 15-20% of patients will require new surgery within 5 years. Close monitoring for postoperative recurrence is therefore needed to perform early intervention and prevent clinical recurrence and need for re-surgery. Endoscopy is the gold standard to assess postoperative disease recurrence however it's limited by its invasiveness. Cross sectional imaging is known for accurate detection of postoperative recurrence. Intestinal ultrasound (IUS) of the colon and (neo)terminal ileum correlates well with CT, MRE and colonoscopy findings in the postoperative setting. IUS is non-invasive, cheap, readily available and may show early, signs of disease recurrence. Therefore it could be a useful tool to predict endoscopic recurrence at 6 months.

结局指标

主要结局

The primary aim of the study is to investigate if IUS (as measured by B-mode and CDS) in combination with faecal calprotectin at 3 months after ICR is an early surrogate marker of endoscopic disease recurrence (as defined by a RS ≥ i2) at 6 months

时间窗: 6 months

次要结局

  • to assess the diagnostic accuracy of FCal at 3 and 6 months to predict and determine endoscopic disease recurrence, respectively(3-6 months)
  • to assess if IUS (as measured by B-mode, CDS and SWE) alone or in combination with faecal calprotectin at 6 months after ICR is accurate in detecting endoscopic recurrence at 6 months (as defined by a RS score ≥ i2 and by the SES-CD˃3)(6 months)
  • to assess if IUS (as measured by B-mode, CDS and SWE) alone or in combination with faecal calprotectin at 12 months after ICR is a surrogate marker of endoscopic disease recurrence (RS≥ 2) at 18 months and/or clinical outcomes at 18, 24, 30 and 36 months(12-36 months)
  • • To assess if IUS (as measured by B-mode, CDS and SWE) alone at 3 months after ICR is an early surrogate marker of endoscopic disease recurrence (as defined by a RS ≥ i2) at 6 months(6 months)
  • to compare IUS (as measured by B-mode, CDS and SWE; alone or in combination with faecal calprotectin) and the RS upon endoscopy at 6 months after ICR for their prognostic role on clinical outcomes upon 3 years of follow-up(6 - 36 months)
  • to develop an IUS score for postoperative recurrence in Crohn's disease(6 months)
  • to assess if SWE during IUS at 3, 6 and 12 months is predictive of anastomotic stenosis upon follow-up(3-12 months)
  • to assess the feasibility of IUS in the postoperative settings for different types of anastomosis(3-6 months)
