Thoracoscopic surgical approaches for treating various thoracic spinal region diseases.

AIM Minimally invasive surgery is currently a goal for surgical intervention in the spine. The effectiveness of endoscopic thoracic spine surgery and technological improvements are two factors that are always under consideration in the practice of spinal surgery. MATERIAL AND METHODS We present twenty-five patients whose thoracoscopic spinal surgeries were performed between 2002 and 2008 for the treatment of various spinal diseases. Eleven patients with thoracic disc herniation, five patients with traumatic thoracic spinal compressive fracture, six patients with metastatic thoracic spinal tumors and three patients with tubercular spondylitis underwent thoracoscopic spine surgery. Clinical evaluations were performed at 3, 6,12 and 24 months post-surgery. The Oswestry disability questionnaire and linear visual analog scale (VAS) were used for the evaluation of pain. RESULTS Postoperatively, two patients had lung contusions, one patient had pneumonia and one patient had instability. There were significant initial improvements in both the Oswestry score and the VAS pain score up to 6 months (p<0.05). The average relative difference in pain scores in all groups was not significant at 12 and 24 months (p>0.05). CONCLUSION The favorable results of thoracoscopic spinal surgery encourage its application to situations in which a conventional thoracic approach is indicated. Thoracoscopic spine surgery is applicable to all patients with various spinal diseases.
