E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Main objective: To evaluate if intestinal wall perfusion, elasticity or peristaltics in patients with CD assessed with the modalities a) dynamic MRI, b) Contrast Enhanced UltraSound (CEUS) or c) Elastography UltraSound (EUS) are correlated to the degree of active or chronic disease and stiffness of tissue. |
|
E.2.2 | Secondary objectives of the trial |
Secondary objective: To evaluate which parameters obtained from intestinal wall perfusion, elasticity or peristaltics in patients with CD assessed with the modalities a) dynamic MRI, b) Contrast Enhanced UltraSound (CEUS) or c) Elastography UltraSound (EUS), as well as postsurgery degree of active or chronic disease and stiffness of tissue that correlates to bloodsamples, fecalsamples and questionnaire results. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |

|
E.5 End points |
E.5.1 | Primary end point(s) |
Preoperative evaluation with MRI, CEUS and EUS will be compared to postoperative specimen degree of 1) Active disease (assessed by histomorphometry and histoligyscore), 2) Chronic disease (assessed by histomorphometry, histologyscore and hydroxyprolin) 3) distensibility (assesses by impedance planimetry). |
