Normal-looking ileocecal valve does not exclude Crohn's disease in the terminal ileum

Introduction: Despite ileoscopy is the only procedure which can accurately detect mucosal abnormalities in the ileum, it is performed only in an average of 5–15% of the colonoscopies in the daily practice. Since ileum alone is affected in about 30% of CD patients, ileal intubation is very important in suspected ileal Crohn's disease (CD). Aim: On the basis of the observation, that a normal-looking ileocecal valve (ICV) suggests the presence of normal ileal mucosa, the aim of this study was to retrospectively determine the predictive value of the endoscopic findings of ICV in patients with CD.
