Diagnostic yield of colon capsule endoscopy for Crohn’s disease lesions in the whole gastrointestinal tract

Abstract Background Crohn’s disease (CD) can involve the upper gastrointestinal (GI) tract as well small and large bowel. PillCam colon capsule endoscopy (PCCE-2) enables observation of whole GI tract, but its diagnostic yield for CD lesions in remains unknown. Aim To elucidate PCCE-2 patients with CD. Methods Patients who underwent double-balloon (DBE) using oral anal approaches were evaluated tract. We divided bowel into three segments (jejunum, ileum, terminal ileum), four (right colon, transverse left rectum). Detection ulcer scars, erosion, ulcers, bamboo joint-like appearance, notch-like appearance was assessed each segment. The analyzed based on DBE results gold standard. Results Of total 124 segments, sensitivities ulcers 83.3%, 93.8%, 88.5%, respectively, specificities 76.0%, 78.3%, 81.6%, respectively. For 60 84.2%, 95.5%, 90.0%, 63.4%, 86.8%, 87.5%, 64 80.0%, 84.7%, 72.2%, 77.6%, Conclusion provides a high Thus, we recommend use pan-enteric tool clinical settings.
