    Abstract:
    BACKGROUND: Video-assisted thoracic operations are usually performed with 5-mm or 10-mm instruments under general anesthesia with single-lung ventilation. Management of peripheral lung nodules by a needlescopic video-assisted thoracoscopic operation, without endotracheal intubation, has rarely been attempted. We evaluated the feasibility and safety of this minimally invasive technique in managing peripheral lung nodules. METHODS: From August 2009 through March 2011, 46 patients with peripheral lung nodules were treated using 3-mm needlescopic video-assisted thoracoscopic operations for wedge resection with epidural anesthesia and sedation, without endotracheal intubation. RESULTS: A definitive diagnosis was obtained in all 46. Extension of the 3-mm incisions was required in 8 patients because of primary lung cancer requiring a lobectomy in 3, pleural adhesions in 3, and difficulty in identifying or resecting the nodule in 2. Two patients required conversion to intubated single-lung ventilation because of dense adhesions between the lungs and the diaphragm. Operations lasted a mean of 69.2 ± 46.8 minutes. Postoperative side effects occurred in 4 patients, including sore throat, headache, and vomiting requiring medication. Operative complications developed in 1 patient who had air leaks for more than 3 days postoperatively. The mean postoperative chest tube drainage and hospital stay were 1.1 days and 2.7 days, respectively. Postoperative neuralgia was noted in 12 patients (26%). Most patients (74%) were very satisfied or satisfied with the resulting scars. CONCLUSIONS: Nonintubated needlescopic video-assisted thoracoscopic operations are technically feasible and safe and may be a less invasive alternative in the management of selected patients with peripheral pulmonary nodules.
