Combined video-assisted mediastinoscopy and thoracoscopy in the management of lung cancer: a five-year experience.
OBJECTIVE
The aim of this study was to assess the usefulness of combined video-assisted mediastinoscopy (VM) and video-assisted thoracoscopy (VT) in the management of patients with lung cancer.


METHODS
A prospective observational study was performed over a 5-year period. Indications for combined VM and VT included inconclusive findings from imaging techniques concerning locoregional extension and resectability; possible involvement of different structures not accessible to a single procedure; and failure to obtain a histologic diagnosis with a single technique.


RESULTS
An indication for combined exploration was established in 30 patients, representing 2.6% of all the patients referred to us for diagnosis, staging, and/or resection of lung cancer. Combined VM and VT was completed in 28 patients, as pleural carcinosis was found at VT in 2 cases. There was no mortality or morbidity in our series. Histologic diagnosis was obtained in 12/13 patients without preoperative histologic typing. In all the evaluated patients, combined VM and VT was useful in clinical decision-making, leading to immediate surgery (n=10), induction treatments (n=8), or nonsurgical therapy (n=12). Among the patients who underwent immediate surgery, combined VM and VT never failed to assess the T factor. The N factor was correctly evaluated in 8/10 patients, and in 2 patients it failed to recognize a minimal N2 disease.


CONCLUSIONS
Combined VM and VT is a safe and useful tool in the management of selected patients with lung neoplasms. Both the extent of primary tumor and the possible intrathoracic spread can be thoroughly evaluated.
