The effect of positions on accuracy by EUS, EBUS and CT in the diagnosis of RLN lymph node metastases.

For the diagnosis of right RLN lymph node metastases, the sensitivity of EBUS was significantly different from that by EUS or CT (P P >0.05). The specificity of the diagnosis by EUS, EBUS and CT showed no significant difference (P >0.05). For the diagnosis of left RLN lymph node metastases, the sensitivity of EBUS showed a statistically significant difference from that by CT (PP >0.05). The sensitivity of this diagnosis by EUS and CT was not significantly different (P >0.05). The specificity of the diagnosis by EUS, EBUS and CT was not significantly different (P >0.05). The testing method was the McNemar Test. The sensitivity and accuracy of PET/CT were not significantly different from those by EUS or EBUS (P >0.05). The testing method was the McNemar Test.The effect of positions on accuracy by EUS, EBUS and CT in the diagnosis of RLN lymph node metastases.在右侧喉返神经（Recurrent Laryngeal Nerve，RLN）淋巴结转移的诊断中，支气管内超声（Endobronchial Ultrasound，EBUS）的敏感度与内镜超声（Endoscopic Ultrasound，EUS）或计算机断层扫描（Computed Tomography，CT）存在显著统计学差异（P<0.05）。内镜超声、支气管内超声与计算机断层扫描的诊断特异度均无显著统计学差异（P>0.05）。针对左侧RLN淋巴结转移的诊断，EBUS的敏感度与CT的检测结果存在显著统计学差异（P<0.05）。EUS与CT的诊断敏感度无显著差异（P>0.05）。内镜超声、支气管内超声与计算机断层扫描的诊断特异度均无显著统计学差异（P>0.05）。本次检验采用麦克尼马尔检验（McNemar Test）。正电子发射断层扫描/计算机断层扫描（Positron Emission Computed Tomography/Computed Tomography，PET/CT）的敏感度与准确度，分别与EUS或EBUS的对应指标均无显著统计学差异（P>0.05）。本次检验采用麦克尼马尔检验（McNemar Test）。体位对EUS、EBUS及CT诊断RLN淋巴结转移准确度的影响。
