Major pulmonary resection by video assisted mini-thoracotomy. Initial experience in 35 patients.

Video-assisted thoracic surgery is emerging as a viable approach to increasingly complex intrathoracic therapeutic procedures. From February to July 1993, 35 patients (25 male, 10 female; mean age = 60 years, range: 17-74) underwent a major pulmonary resection using a video-assisted technique: lobectomy (n = 30) or pneumonectomy (n = 5). Pathology disclosed bronchogenic carcinomas (n = 26), metastases (n = 3), and miscellaneous disorders (n = 6). All procedures required one 10.5 mm port for the video-camera, one 3.5 to 5 cm utility thoracotomy through which surgical instrumentation was inserted and the operative specimen removed, and one occasional supplementary 12 mm port. Lung resections were performed with separated dissection and division of each component of the pedicle. The mean operative time was 145 min (SD: +/- 17). There were two postoperative deaths (5.7%) that were not directly related to the technique. Seven patients (20%) experienced non-fatal complications. After lobectomy, the mean duration of chest tube placement was 7.3 days (SD: +/- 1.6). The mean hospital stay was 11 days (SD: +/- 3). All the patients experienced minor postoperative chest pain. We conclude that video-assisted lung resections are technically feasible without an increased risk.
