【摘要】 目的探讨经纤维支气管镜(纤支镜)针吸活检术(TBNA)对纵隔非肿大淋巴结穿刺活检的价值。方法对137例肺癌患者X线体层、CT、MRI提示纵隔淋巴结不肿大者经纤支镜行TBNA检查。结果该方法准确性为96.4%,对肺癌纵隔非肿大淋巴结的转移诊断率为24.1%,其中跳跃式淋巴结转移率为13.2%。结论该方法能够明确肺癌纵隔非肿大淋巴结的性质,对肺癌术前诊断分期、术中确定纵隔淋巴结清除范围及估计预后均具有重要意义。是一种结果准确、操作方便、安全的临床实用方法。更多还原

【Abstract】 Objective: To ascertain the nature of non-enlarged mediastinal lymph nodes. Methods: 137 patients with non-enlarged mediastinal lymph nodes designed by X-ray, CT or MRI were biopsied. Results: The accurate rat was 96.4%. The diagnosis rat of non-enlarged mediastinal lymph nodes from lung cancer was 24.1%, of which, the jumped-metastase rat was 13.2%. Conclusions: The method wasusefull in ascertaining the nature of non-enlarged mediastinal lymph nodes, and was necessary for diagnsis. As a clinic method, it was accuray, simple and safe.更多还原
