Mediastinopleuroscopy: a new approach to the diagnosis of intrathoracic diseases

Abstract

With the advent of modern therapy, it has become essential to obtain a tissue diagnosis in all cases of pulmonary and mediastinal disease. Since it is often necessary to resort to thoracotomy as a final step in making such a diagnosis, we have sought a procedure that is simpler while capable of providing the same information. Through a standard cervical mediastinoscopy incision, the mediastinum is first explored; if the diagnosis is not obtained, the mediastinal pleura is digitally opened and lung or pleural biopsies are taken. In the course of 1,100 mediastinoscopies since 1969, 275 pleuroscopies have been done. We were able to obtain a tissue diagnosis in 102 (78%) of 131 patients with bronchogenic carcinoma, in 92 (91%) of 102 with benign pulmonary disease, and in all 20 (100%) with pleural disease.
