Capsule endoscopy findings in patients with established and suspected small-bowel Crohn's disease: correlation with radiologic, endoscopic, and histologic findings.
Little is known about the accuracy of capsule endoscopy (CE) in evaluation of small-bowel Crohn's disease.. Symptomatic eligible patients had ileocolonoscopy and biopsies from the terminal ileum, followed by small-bowel radiologic studies before CE. Endoscopic, radiologic, CE, and histologic findings were compared. Histology (terminal ileum biopsy specimens or a tissue sample after small-bowel resection) served as a criterion standard.. Fifty-four patients were enrolled; 15 of the 54 patients were excluded from data analysis (critical small-bowel strictures, 14, identified on radiology; incomplete CE, 1). Data were analyzed for 39 patients. All patients had histologic evaluation of the small bowel. Final diagnosis of active small-intestine Crohn's disease was made in 29/39 patients (74.4%). When calculated, CE yielded a sensitivity and a specificity of 89.6% and 100.0%, respectively, and a positive predictive value and a negative predictive value of 100.0% and 76.9%, respectively, whereas small-bowel series were 27.6%/100.0% and 100.0%/32.3%.. CE is more accurate in detecting small-bowel inflammatory changes suggestive of Crohn's disease than conventional studies. CE, combined with ileocolonoscopy, may be proposed as a first-line investigation of the small intestine in cases of uncomplicated known or suspected Crohn's disease.

Assessment of small bowel Crohn disease: noninvasive peroral CT enterography compared with other imaging methods and endoscopy--feasibility study.
A feasibility study was conducted to evaluate two biphasic computed tomographic (CT) enterography protocols, a noninvasive CT technique with water administered perorally and CT enteroclysis with methylcellulose administered through a nasojejunal tube, in 23 patients known or suspected to have Crohn disease. Results were compared with the results of fluoroscopic small bowel examination and terminal ileoscopy for the detection of active Crohn disease in the terminal ileum. Luminal distention did not differ significantly between the two CT protocols. Arterial phase imaging was noncontributory in 22 of 23 cases. The noninvasive peroral water CT enterography protocol had similar accuracy (12 of 15 cases, 80%) for enabling the detection of active Crohn disease in comparison with CT enteroclysis with nasojejunal tube (seven of eight, 88%) and fluoroscopic small bowel examination (17 of 23, 74%). No fistulas were missed with use of either CT technique. The authors conclude that noninvasive peroral portal venous phase CT enterography with use of water is an accurate and feasible technique for detecting active small bowel inflammation in patients with Crohn disease.
