Successful thoracoscopic resection of pulmonary metastasis less than 1 cm in size utilizing preoperative CT-guided wire localization.

Preoperative computer tomography (CT) guidance localization utilizing a percutaneous guidewire before thoracoscopic resection is safe and beneficial in children with pulmonary nodules less than 1 cm in size or located deep in the pleural surface. This paper describes a successful thoracoscopic resection of a little subpleural pulmonary metastasis of a Wilm's tumor in a 5-year-old child utilizing preoperative CT-guided wire localization of the lesion. The thoracoscopic procedure was performed with the use of two ports, the nodule was easily localized,and the pulmonary wedge resection was made by the use of an endo-GIA linear stapling device after guidewire removal.
