Abstract
To localize small and deeply situated pulmonary nodules during thoracoscopy with roentgenographic fluoroscopy, we developed a marking procedure that uses a metallic coil. Nine patients underwent video-assisted thoracoscopic surgery for the removal of 11 pulmonary lesions. Fluoroscopy-assisted thoracoscopic surgery after computed tomography-guided bronchoscopic metallic coil marking was performed with an ultrathin bronchoscope, with simulation by means of virtual bronchoscopy. During thoracoscopy, a C-arm-shaped roentgenographic fluoroscope was used to detect the radiopaque nodules. The marking procedure took 15 to 60 minutes from insertion to removal of the bronchoscope. There were no complications from the marking, and all 11 nodules were easily localized by means of thoracoscopy. The metallic coil showed the nodules on the fluoroscopic monitor, which aided in nodule manipulation. Nodules were completely resected under thoracoscopic guidance, except in one case in which a minithoracotomy was performed at an early stage of the trial. The pathologic diagnosis was primary adenocarcinoma in 9 patients, pulmonary metastasis from colon cancer in 1 patient, and pulmonary lymph node in 1 patient. Two cases of bronchioloalveolar adenoc...Continue Reading
