Mediastinoscopy and CT in the Diagnosis of Chest Diseases the Use of Research

目的:探讨电视纵隔镜与CT对胸部疾病诊断中的运用。方法:对我院收治的59例胸部疑难疾病患者采用CT以及电视纵隔镜检查,并对两种方法对肺癌纵膈淋巴转移的诊断效果进行比较。结果:所有患者采用纵隔镜检查其确诊率为100%,CT诊断诊断符合率为52.5%;CT对肺癌纵隔淋巴结转移的灵敏度为55.26%、真实性为57.89%、特异度为60.53%、阳性预测值为44.74%以及阴性预测值为81.58%,而电视纵隔镜其分别为94.74%、97.37%、100.00%、100.00%、97.37%。电视纵隔镜在诊断肺癌纵膈淋巴结转移的各项指标中均优于CT。结论:电视纵隔镜对胸部疑难疾病具有较好的诊断效果,而且其具有并发症少等特点。

Objective： To investigate the video mediastinoscopy and CT in the diagnosis of chest diseases. Methods： 59 cases in our hospital chest in patients with incurable diseases using CT as well as TV mediastinoscopy, to compare the two methods in the diagno- sis of lung cancer, mediastinal lymph metastasis. Results： All patients using mediastinoscopy and the diagnosis was 100%, the CT diag- nosis of diagnosis was 52.5%; sensitivity of CT for mediastinal lymph node metastasis was 55.26%, the authenticity of 57.89% and a specificity of 60.53%, positive predictive value Mediastinoscopy were 44.74% and negative predictive value 81.58% 94.74% 97.37% 100.00%, 100.00%, 97.37%. Mediastinoscopy is superior to CT in the diagnosis of lung cancer mediastinal lymph node metastasis of the indicators. Conclusion： Mediastinoscopy incurable diseases of the chest has a better diagnostic results, and with fewer complications.
