Abstract
A mong the various uses of videoassisted thoracic surgery is resection of peripheral pulmonary nodules, which has been used not only for therapy but also for diagnostic excisional biopsy [ 1 , 2]. Video-assisted thoracic surgery is indicated when a nodule is too small for percutaneous needle biopsy or when the biopsy is nondiagnostic. However, preoperative localization of a pulmonary nodule is sometimes necessary if the target nodule is too small or too far from the pleural surface to be detected by thoracoscopy or palpation by surgeons. We developed a system using a short hookwire and suture designed to resolve most of the drawbacks of previously reported localization methods [3-7], including possible hypotension from dye infusion, wire dislodgment, pneumothorax, and chest pain. In one study, we reported our early experience with two patients [8]. In this report. we describe further observations on the new system and its use in a series of patients.
