The Value of Mediastinoscopy for Evaluation of Mediastinal Lymph Nodes in Bronchogenic Carcinoma : Accuracy of Mediastinoscopy
원발성 폐암에서 종격동 림프절 평가에 대한 종격동경 검사의 가치
Abstract
For the period from June 1988 to July 1991 we studied 29 patients who were judged to have operable disease before mediastinoscopy on clinical criteria[absence of distant metastases, phrenic or laryngeal nerve paralysis, positive scalene node biopsy, and malignant pleural effusion]. All patients had computed tomography and mediastinoscopy prior to operation. In the present study, the sensitivity, specificity, and accuracy of CT were 92%, 56%, and 72%, respectively. And the sensitivity, specificity, and accuracy of mediastinoscopy were 92%, 100%, and 97%, respectively. We concluded that because of the low accuracy of CT, CT cannot replace mediastinoscopy, and routine mediastinoscopy should be performed in preoperative staging of bronchogenic carcinoma.
