Background: To investigate the role of curative and palliative surgical treatment of lung cancer with video-assisted thoracoscopic surgery (VATS).
Methods: Forty-three patients with lung cancer were prescribed operations with VATS, which included 5 cases of stage IA, 14 cases of IB, 1 case of IIA, 4 cases of IIB, 7 cases of IIIA, 6 cases of T4-IIIB and 6 cases of IV. The 7 patients of stage IIIA were previously staged as N0 before operation, but reevaluated as N2-IIIA after operation. There were 3 cases of malignant pleural effusion and 3 cases of pleural implantation in stage IIIB cases. There were 2 cases of cardiac tamponade, 1 case of solitary brain metastasis, and 3 cases of ipsilateral or contralateral solitary lung metastasis in cases of stage IV. The main methods of operation performed included lobectomy in 36 cases, wedge resection in 5 cases, and pericardial opening in 2 cases. Systemly mediastinal lymph node dissections were performed in 36 cases. Concurrent contralateral pulmonary wedge resections were performed in 2 cases of contralateral solitary lung metastasis. Malignant pleural effusions were prescribed resection of implantation nodules, electrocautery and pleurodesis.
Results: There was no perioperative death or bronchial leak. Five cases suffered lung infection, and 2 cases occurred with incision infection. Malignant pleural effusion in the 3 cases was controlled satisfactorily. Two cases of pericardial opening died in 4 months and 8 months after operation respectively. The other patients were alive till present. Postoperative hospital stay was 5-15 days with average of 7.4 days, except of two cases of pericardial opening.
Conclusions: VATS is an alternative way for complete resection of early stage lung cancer. It is technically feasible to dissect mediastinal lymph node for accidental N2 lung cancer. VATS has significant advantage in concurrent bilateral pulmonary resection. The palliative operation of malignant pleural effusion and cardiac tamponade by VATS can markedly improve the quality of life of patients.
