Video-assisted thoracoscopic excision of herniated thoracic disc: description of technique and preliminary experience in the first 29 cases.

This study evaluates the technique and results of video-assisted thoracoscopic surgery (VATS) for the treatment of symptomatic thoracic disc herniation. Results were compared with a literature review of open surgical techniques of thoracic disc excision with regard to efficacy, safety, and surgical outcomes. VATS has recently been described for thoracic surgery as having the advantage of decreased postoperative pain and morbidity, faster patient recovery, and shortened intensive care unit (ICU) hospitalization. Twenty-nine consecutive patients underwent VATS for symptomatic thoracic disc herniation. Herniations ranging from T5-6 to T12-L1 were successfully approached by using a three- or four-portal strategy. Postoperative magnetic resonance imaging (MRI) scans were evaluated. Pre- and postoperative Oswestry Disability Questionnaires and Linear Analog Pain Scale data were obtained. Patients were grouped according to presenting symptoms. The minimal follow-up was 1 year (range, 12-24 months). Mean operative time was 175 min for 29 patients. Significant improvement (p < 0.01, paired t test) was recorded in Oswestry Disability Questionnaires and Linear Analog Scale Tests. Of the patients, 75.8% (22) were satisfied, 3.4% (one) unsatisfied, with 20.1% (six) unchanged. Narcotic use was significantly eliminated or reduced. Mean return to work was 5 weeks (private insurance) and 21 weeks (workers compensation). The surgical and postoperative complication rate was 13.8%. VATS appears to be a safe and efficacious method of excising herniated thoracic discs. Follow-up results at 1 year resulted in high patient satisfaction. VATS advantages include decreased length of hospitalization as well as improved patient comfort.
