Thoracoscopic fine-needle aspiration of solitary pulmonary nodules.

To determine the diagnostic efficacy of thoracoscopic fine-needle aspiration (FNA) of solitary pulmonary nodules suspicious for lung cancer, we performed intraoperative thoracoscopic FNA for diagnostic purposes in 8 consecutive patients with peripheral solitary pulmonary nodules suspicious for lung cancer. Thoracoscopic FNA yielded an accurate diagnosis in all cases. There were 5 cases of non-small cell lung carcinoma, 1 small cell lung carcinoma, 1 renal carcinoma metastasis, and 1 inflammatory nodule. Results of FNA were obtained in less than 10 minutes in 6 cases. Maximum time to diagnosis was 20 minutes. The surgical procedure was expedited in the 6 cases of lung cancer because lobectomy followed FNA rather than the performance of a diagnostic wedge resection. A minor hematoma after FNA was the single complication. Thoracoscopic FNA yielded a prompt and accurate diagnosis of peripheral solitary pulmonary nodules. Thoracoscopic FNA should be considered as an alternative to preoperative percutaneous FNA, which risks pneumothorax and patient discomfort. In cases of lung cancer, thoracoscopic FNA allows the surgeon to bypass a diagnostic wedge resection and to proceed with definitive lobectomy.
