  • Title: Anterior thoracic corpectomy for spinal cord decompression performed endoscopically.

    Journal: Surg Laparosc Endosc; 1995 Oct; 5(5):339-48. PubMed ID: 8845976.
    Abstract:
    A prospective study was undertaken during the past 3 years to investigate the effectiveness of thoracoscopic corpectomy--endoscopic removal of the vertebral body in 15 cases (8 for pathologic fractures for tumors, 5 for traumatic fractures and 2 for infections). The average age of the patients was 53.2 years (range 28-85 years). The vertebral levels of corpectomy ranged from T3 to L1. The mean operating time was 211 min (range 83-450 min) and the mean estimated blood loss was 890 ml (range 150-2,800 ml). The postoperative morbidity appeared to be more favorable than with open thoracotomy [Alband OW, Corkill G. Thoracic disk herniation: treatment and prognosis.

Overall, the ability to visualize the anterior surface of the dura during corpectomy was better endoscopically than with open thoracotomy techniques--improved magnification, the ability of the operative assistant to see and therefore suction more efficiently, and the perspective of visualization was improved. It was possible to place the 30 degrees angled endoscope within the defect left by the resected vertebral body and look directly posteriorly at the dura, visualizing the epidural vessels and dural pulsations at close range. The limiting factor in wide application of the technique is the absence of a commercially available internal fixation system that can be applied endoscopically.
