The mediastinoscopy was a well known useful diagnostic tool for detection of certain mediastinal tumors, mediastinal lymph nodes invasion by bronchogenic carcinoma and metastatic cancer. A total of 33 cases of mediastinoscopies were reviewed,
which
were
experienced at Chon Buk National University Hospital from August, 1980 t October 1991.
Mediastinoscopy was performed through anterior or parasternal approach in 18 cases, cervical approach in 14 cases and both in 1 case. In 12 cases which were used for preoperative staging of lung cancer, 10 cases(83.3%) had the positive biopsy
results at
mediastinal nodes.
In 11 cases for diagnosis of lymph nodes and masses with unknown lung lesion, small cell carcinoma revealed in 3 cases, squamous cell carcinoma in 2 adenocarcinoma in 1 case and the others were had the negative biopsy results. In 10 cases of
diagnosis
of mediastinal tumors, lymphoma revealed in 2 cases, malignant thymoma in 2, sarcoidosis in 2 tuberculous granuloma in 1, mesothelioma in 1, metastatic cancer with unknown origin in 1 case.
Thoracotomy was performed in 3 cases of lung cancers, 2 patients with negative biopsy results in preoperative staging and 1 patient with subcarinal lymph node involvement only.
Bleeding complications during mediastinoscopy were developed in 2 cases, managed by anteriormini-thoracotomy. (Korean J Thoracic Cardiovas Surg 1993;26:705-9)
