Utility of Capsule Endoscopy for the Classification of Crohn's Disease: A Multicenter Study in Korea
Capsule endoscopy can detect lesions associated with Crohn's disease in the small bowel that go unrecognized by conventional radiologic imaging. The aim of this study was to assess the value of capsule endoscopy in the classification of patients with Crohn's disease. This study was carried out on 52 patients with known Crohn's disease. Small bowel follow-through findings were compared with capsule endoscopic findings. All patients were classified according to the extent of the disease: small bowel-colon type, small bowel type, or colon type. Seventeen patients who were reported as being normal showed evidence of small bowel Crohn's disease according to capsule endoscopy. Differences were observed between the small bowel follow-through and the capsule endoscopy classification (κ=0.54). Treatment was changed based on the results of wireless capsule endoscopy in 15 patients.
