Diagnostic value and clinical safety of capsule endoscopy for obscure gastrointestinal bleeding

Objective To evaluate the diagnostic value and clinical safety of capsule endoscopy for obscure gastrointestinal bleeding. Methods 52 patients suffering from obscure gastrointestinal bleeding were examined by capsule endoscopy. Results Among 52 patients,50 completed the examination of capsule endoscopy,with the successful rate of 96. 2%. Capsule retention occurred in 2 patients,which was removed by surgery. Pathological changes were detected in 31 ones,with the positive rate of 59. 6%. The findings included 2 cases of suspicious lesions,2 cases of vascular bleeding,14 cases of ulcer and inflammation,3 cases of lymphoid hyperplasia,1 case of diverticulum,and 3 cases of active bleeding influencing visual observation. Conclusion Capsule endoscopy is safe and valuable for the diagnos of the obscure gastrointestinal bleeding.
