Background: To show the safety and stability of a spiral wire needle (Somatex; Rietzneuendorf, Germany) in the detection and subsequent thoracoscopic resection of subpleural and/or small nodules of the lung.

Methods: Under local anesthesia and CT control, 13 patients underwent the positioning of a spiral wire needle into the lung, with the spiral located close to or inside the nodule to be resected. Then the patients underwent video-assisted thoracoscopic surgery resection of the nodules with only two thoracoscopic accesses.

Results: All the nodules were identified due to the precise location of the spiral wire needle. The presence of a stable spiral wire inside the parenchyma has allowed us to put under tension the overlying parenchyma, which had previously been excluded from ventilation. The external traction on the needle facilitates the detection of the nodule and simplifies thoracoscopic resection with a stapler. With this new tool, we have always reached an adequate diagnosis and observed no cases of dislodgment of the needle during the traction maneuvers, nor cases of conversion from thoracoscopy to thoracotomy.

Conclusions: Although our initial experience is limited, the use of this spiral wire needle has been shown to be extremely advantageous in identifying subpleural and/or small nodules of the lung, even sparing the classic third thoracoscopic access for their resection. The presence of a wire needle with a spiral terminal portion (which is placed firmly inside the lung parenchyma) is very useful for the thoracoscopic resection of pulmonary nodules.
