胸部疾患例におけるScalene Node Biopsy及びMediastinoscopyの臨床的並びに病理学的検討 (特に肺癌を中心として)

抄録

The study is to evaluate the validity of scalene node biopsy and mediastinoscopy as methods of clinical examination on various pulmonary disabilities and to discuss the possible route of lymph node metastasis of cancer of the lung.
In a 4 year duration til June, 1966, 111 patients were examined and those included 45 patients of cancer the lung, 17 mediastinal tumor, 10 pulmonary tuberculosis, 8 sarcoidosis, 6 metastatic tumer of the lung and others. In general, scalene node biopsy and mediastinoscopy were infrequently positive in patients with pulmonary diseases unless the mediastinum were involved by the disease or the patients had sarcoidosis.
From the study of cervical lymph node and mediastinal metastases of cancer of the lung based on both examinations of biopsy and mediastinoscopy, an obvious route of metastasis was determined in none of each case and it was considered that metastases were produced via the much complicated route of lymphatic system. Considering the validity of scalene node biopsy and mediastinoscopy, as methods of pre-operative examination, it was assured that scalene node biopsy, as biopsy of distant lymph node from the lung, is an useful method fo- determination of indication of surgery, and mediastinoscopy as a good tool of examination of the mediastinum is useful to determine operability of the lesion of the lung.
