Résumé
Les examens morphologiques digestifs disponibles sont d’utilité différente, selon que l’on considère le stade initial de diagnostic d’une maladie de Crohn (MC), son suivi évolutif ou la recherche d’une complication. Les examens endoscopiques sont une étape incontournable de l’établissement du diagnostic. La vidéocapsule endoscopique et l’entéro-IRM permettent d’identifier des lésions intestinales, mais celles-ci seront au mieux confirmées par l’entéroscopie poussée ou double ballon. Les examens irradiants sont à éviter autant que possible pour faire le bilan morphologique lésionnel à froid d’une MC. Le scanner abdominal reste l’examen clé, en urgence, devant la suspicion d’une complication digestive.

Abstract
The utility of morphological digestive explorations available depends on whether we take into consideration the initial phase of Crohn’s disease, its evolution or a search for disease complications. For assessing the diagnosis, endoscopical examinations are an indisputable step. Videocapsule endoscopy and entero-MRI can identify intestinal lesions, but these are confirmed even more with push or double balloon enteroscopy. Radiological explorations should be avoided as much as possible when carrying out cold lesion morphology assessments of CD. Abdominal CT-scan is the best exploration to perform, in an emergency, in a suspected case of digestive complications.
