The PillCam ESO (Given Imaging, Israel) or esophageal capsule endoscopy (ECE) is a novel technique used in the diagnostic evaluation of esophagus. Many studies have been performed to compare the accuracy of ECE against the current gold standard esophago-gastro-duodenoscopy and a meta-analysis recently published by Lu et al suggests that ECE may have an acceptable sensitivity and specificity in detecting esophageal varices. We would like to discuss the importance and implication of publication bias in this meta-analysis.
PillCam ESO（以色列 Given Imaging 公司）或食管胶囊内镜（ECE）是一种用于食管诊断评估的新技术。已经进行了许多研究来比较 ECE 与当前的金标准食管胃十二指肠镜检查的准确性，最近 Lu 等人发表的荟萃分析表明，ECE 在检测食管静脉曲张方面可能具有可接受的敏感性和特异性。我们想讨论该荟萃分析中发表偏倚的重要性和影响。
