Abstract
Video-assisted thoracic surgery (VATS) may be used for resection of posterior mediastinal tumors to avoid thoracotomy and shorten hospital stay. Between October 1990 and June 1998, 23 patients had VATS resection of posterior neurogenic tumors. The 14 females and 9 males ranged in age from 14 months to 70 years, with a median of 35 years. Operation time ranged from 30 to 120 minutes (median, 83), and intraoperative complications were limited to minor problems as well as conversion to thoracotomy to enhance complete tumor resection in four cases. Tumor pathology included nerve sheath origin (20) and autonomic ganglia (3). There was only one malignant schwannoma. Tumor size ranged from 0.7 to 13 cm in diameter. Median chest tube days was 1 day (range, 1–4), and hospital stay was 2 days (range, 1–9). Postoperative complications included transient paresthesia (three cases), ileus (two cases), pleural effusion (one case), and transient intercostal pain (one case). Posteripr neurogenic tumors may be resected safely using video-assisted techniques. Conversion to thoracotomy to enhance complete resection is both possible and encouraged. The use of VATS seems to decrease hospital stay and minimize postoperative complications. In posterior neurogenic tumors without tumor extension to the spinal canal, VATS has become our preferred method for resection.
