While performing thoracoscopic wedge resection of the lung, the location of the lesion is generally identified by visual inspection or palpation. When difficulty in identification of the lesion by thoracoscopy is anticipated, preoperative marking is performed. However, complications and technical difficulties plague current marking techniques. To overcome this problem, we performed CT-guided skin marking above the pulmonary nodule. We used this technique to treat 25 lesions of 22 patients. Median tumor diameter was 9.5mm. All lesions were identified by finger tips via thoracoscopy, all nodules were constrained by ring forceps, and wedge resections were performed using a stapler. All lesions lay very close to the markings, as judged by finger palpation. No complications were encountered. The advantages of our technique are that it is simple and easy, air emboli are not an issue, the skin marking is rapid, and safety is assured.
