Thoracoscopy for intrathoracic tumors

Abstract

The technique of thoracoscopy has been performed on 49 occasions in 45 patients for the diagnosis or staging of intrathoracic tumors. The patients ranged from 8 months to 68 years old. Eight procedures were performed for pleural disease, 16 for mediastinal masses, 22 for parenchymal lesions, and 3 for intrathoracic staging. Seventeen patients had had previous invasive procedures performed without a pathological diagnosis being established. In 28 thoracoscopy procedures, a positive diagnosis for malignancy was obtained; in 6 instances, areas of unsuspected tumor involvement were identified. A correct diagnosis was obtained by thoracoscopy in 45 procedures for a 92% overall accuracy rate. There was no clinically significant morbidity in this series and no procedure-related mortality. Thoracoscopy, performed under stellate ganglion block and regional anesthesia, has proved to be a very attractive method of diagnosing intrathoracic neoplasia with very low morbidity.
