Thoracoscopy for intrathoracic neoplasia in children.
The technique of thoracoscopy allows a unique opportunity to examine the entire hemithorax. Between July 1975 and April 1981 we performed over 150 thoracoscopic procedures for evaluation of intrathoracic pathology at the University of Florida. Twenty-five of these procedures, performed in 23 patients, were undertaken for the diagnosis or staging of intrathoracic tumors in patients whose ages ranged from 8 mo to 18 yr. Forty-eight percent were for parenchymal tumors, 44% for mediastinal masses, and 8% for pleural disease. Twelve of these patients had at least 1 invasive procedure performed prior to thoracoscopy without a diagnosis being established. In 17 procedures a positive tissue diagnosis of malignancy was obtained, and in 6 of these cases areas of previously unsuspected intrathoracic tumor involvement were identified by thoracoscopy. In 3 patients simultaneous thoracoscopy-guided transdiaphragmatic needle biopsy of the liver was performed with a positive tumor diagnosis being achieved in 1. The clinical course of the patients following the 8 procedures in which neoplasia was not encountered confirmed the diagnosis of benign disease in all but 1. A single patient with an enlarged mediastinal lymph node had a falsely negative thoracoscopy biopsy and was subsequently diagnosed as having recurrent Hodgkin's disease. The overall diagnostic accuracy in these patients was, therefore, 92%. Complications in these patients have been minimal, and there was not mortality due to the thoracoscopic procedure. These clinical results would suggest an important role for thoracoscopy in the evaluation of intrathoracic neoplasia in children.
