NEEDLE LOCALIZATION OF PERIPHERAL LUNG NODULES FOR VIDEO-ASSISTED THORACOSCOPIC SURGERY

Video-assisted thoracoscopic surgery provides an alternative to conventional thoracotomy for resection of peripheral lung nodules. To localize small peripheral lung nodules that may not be visible or palpable by the surgeon, we have placed a Kopans hook wire percutaneously into the lung as a guide. The indications for localization included previous nondiagnostic percutaneous needle aspiration biopsy (PNAB) (n=4), nodules too small for PNAB (n=2), nodules inaccessible to PNAB (n=3), and planned resection of a known peripheral tumor less than 1 cm (n=1). The localization procedure was performed with computed tomographic guidance in all patients. The nodules ranged in size from 2 to 15 mm and were located immediately subpleural to 2-cm deep the pleura. A 20-gauge Greene biopsy needle was used as an introducer for a 35-cm-long Kopans hook wire. Patients were sent directly to the operating room in a dependent position. All ten nodules were successfully resected, including hamartoma (n=1), carcinoid tumors (n=2), granulomas (n=3), adenocarcinoma (n=1), fibrosis (n=1), benign metastasizing leiomyoma (n=1), and lymphoma (n=1). In two patients, the wire slipped out of the lung. Small focal pneumothoraces developed in five patients. There were no major complications. This procedure can safely and effectively localize nonvisible or nonpalpable pulmonary nodules for thoracoscopic surgery for diagnostic purposes or for resection of small peripheral tumors in patients who cannot tolerate a lobectomy or pneumonectomy.
