 The aims of this study are as follows: 1 to describe the spectrum of small intestinal lesions demonstrated by capsule endoscopy CE in patients with Crohns disease; 2 to determine the inter-observer agreement for recognizing these small intestinal lesions; 3 to determine the sensitivity, positive predictive value, and accuracy of CE, CT enterography, small bowel follow-through, colonoscopy with ileoscopy, and all pairwise combinations of these examinations with a consensus clinical diagnosis for the diagnosis and evaluation of the extent and severity of small intestinal Crohns disease; 4 to establish a Crohns Disease Capsule Endoscopy Index of Severity CDCEIS; 5 to describe the spectrum of right colon lesions demonstrated by CE in patients with Crohns disease.
