[Approach by clamshell incision for bilateral pulmonary metastasis].

In recent years thoracotomy by "clamshell incision" has frequently been chosen for heart-lung transplantation, bilateral lung tumors and mediastinal tumor merging into lung tumor because this approach provides very good visibility to access the whole bilateral lung including the lower lobe and mediastinal organs. In our hospital, 4 patients underwent bilateral thoracotomy by clamshell incision for pulmonary metastasectomy between 2001 and 2005. All cases had bilateral pulmonary metastases, and multiple wedge resection was performed. All lesions that were planned for resection on preoperative computed tomography (CT) could be resected. Regarding the surgical approach to bilateral pulmonary metastases that did not need lobectomy, clamshell incision is one of the useful approaches that can allow wedge resection anywhere in the whole lung. In cases that are expected multiple procedures, bilateral thoracotomy by clamshell incision is recommended because it allows another route for thoracotomy at reoperation.
