目的:分析胶囊内镜在不明原因消化道出血疾病中的诊断价值。方法:选择2013年1月-2014年6月广东省湛江市中心人民医院收治的不明原因消化道出血患者62例,行胶囊内镜检查,分析胶囊内镜对不明原因消化道出血的诊断价值及不同时机消化道出血原因的检出率。结果:胶囊内镜检查不明原因消化道出血疾病的阳性率77.42%、阴性率14.52%、疑诊率8.06%;诊断敏感度97.92%、特异度88.89%、阳性预测值88.68%、阴性预测值88.89%;且活动性出血组出血原因检出率明显高于出血停止组(P<0.05)。结论:胶囊内镜诊断不明原因消化道出血疾病是一种安全、有效的手段,若在患者出血期间行胶囊内镜检查,能进一步提高诊断率。
Objective: To analyze the diagnostic value of capsule endoscopy in the diagnosis of gastrointestinal bleeding with unknown causes. Methods: From January 2013 to June 2014, 62 patients with unexplained gastrointestinal bleeding admitted to Zhanjiang Central People’s Hospital of Guangdong Province were enrolled. The capsule endoscopy was performed to analyze the diagnostic value of capsule endoscopy in the diagnosis of unexplained gastrointestinal bleeding. Different timing of gastrointestinal bleeding causes the detection rate. Results: The positive rate of gastrointestinal bleeding was 77.42%, the negative rate was 14.52%, the suspect rate was 8.06%. The diagnostic sensitivity was 97.92%, the specificity was 88.89%, the positive predictive value was 88.68%, the negative predictive value was 88.89 %. The detection rate of hemorrhage in active bleeding group was significantly higher than that in bleeding stopped group (P <0.05). Conclusion: The diagnosis of unexplained capsule endoscopy gastrointestinal bleeding is a safe and effective means, if the endoscopic diagnosis of bleeding during the patient can further improve the diagnostic rate.
