OBJECTIVE: To investigate clinical diagnostic value of capsule endoscopy in obscure gastrointestinal bleeding.
METHODS: Capsule endoscopy were performed in 90 patients with obscure gastrointestinal bleeding, which was defined as negative finding by gastroscopy and colonoscopy in our hospital.
RESULT: In 90 patients, 2 of them accepted second examination. Eighty-seven of 92 (94.57%) patients accepted of capsule endoscopy successfully including 21 of 25 (84.0%) in group of acute massive bleeding and 66 of 67 (98.51%) in recurrent melena (P <0.05). In above patients, 74 of 87 (85.06%) had positive findings and the false negative rate was 17.24%. The detectable rate in acute massive bleeding and recurrent melena was 80.95% and 86.36%, respectively (P >0.05), and the false negative rate of that was 23.81% and 15.15%, respectively (P >0.05).
CONCLUSION: Capsule endoscopy can be performed safely and well-toleratedly for visualizing the small bowel in patients with obscure gastrointestinal bleeding, which induces a highly detectable rate compared with other methods for detecting obscure gastrointestinal bleeding.
