STRICTuring Crohn’s disease assessment using advanced Ultrasound and magnetic REsonance imaging techniques for evaluation of inflammation and fibrosis (STRICTURE)

Aim of research
Patients with Crohn’s Disease present predominantly with inflammation; however, a significant proportion of patients already exhibit strictures at diagnosis or develop fibrostenotic complications during their disease course. Whereas predominantly inflammatory strictures are likely to benefit from medical therapy, predominantly fibrotic strictures often require a surgical approach. As strictures are rarely identified merely as fibrotic or inflammatory, identifying the predominant component of the stricture is necessary to guide clinical decision making. However, currently used imaging modalities are unable to adequately determine stricture composition.
Intestinal ultrasound (IUS) and MRI are both frequently used in the evaluation of disease activity in CD. Previous studies have shown that advanced modalities of both techniques are promising for the characterisation of stricture composition. However, data are scarce and most studies have not combined MRI and IUS parameters.
Therefore, the aim of the STRICTURE study is to evaluate the use of state-of-the-art cross-sectional imaging parameters to identify stricture composition, as defined by the histopathological degree of inflammation and fibrosis in the surgical resection specimen.
