[Video-assisted thoracic surgery (VATS) for metastatic lung tumor: comparison with thoracotomy].
Effectiveness and present problems of video-assisted thoracic surgery (VATS) for metastatic lung tumor were investigated by comparing 14 cases (16 operations) of VATS with 16 cases (19 operations) of conventional thoracotomy during the same period. VATS was favorably selected in the solitary metastasis. The cases who had small tumor diameter less than 3 cm and shorter distance from viseral pluera to the tumor surface than tumor diameter were advantageous for only thoracoscopic procedure to do the safe and sure resection. Regarding to the tumor number, we detected another tumor intraoperatively in 2 of 16 cases (12.5%) of VATS and 6 of 19 cases (31.6%) of thoracotomy. Multiple metastases had the tendency to have the differences of the tumor number between preoperation and intraoperation. Prognosis is very good until now, but the recurrence rate was high (64.5%) and one case had the recurrence at the surgical margin. VATS for metastatic tumor is very effective, but it is important not to hesitate to do the mini-thoracotomy and convert to conventional thoracotomy for safe and sure resection.
