Video-assisted thoracoscopic surgery (VATS) shows feasibility for thoracic discectomies, potentially reducing invasiveness. Further instrumentation development is needed for this minimally invasive approach to become a standard surgical alternative.

Area of Science:

  • Minimally invasive spinal surgery
  • Thoracic surgery techniques
  • Surgical innovation

Background:

  • Video-assisted thoracoscopic surgery (VATS) has been utilized for pulmonary resections since 1991.
  • The application of VATS for thoracic disc resections remains unexplored.

Purpose of the Study:

  • To investigate the feasibility of utilizing VATS for thoracic discectomies.
  • To assess the potential of VATS in performing thoracic disc resections with reduced invasiveness.

Main Methods:

  • A laboratory study involving two human cadavers and three live pigs.
  • Nine thoracic disc levels were decompressed using VATS.
  • VATS provided visualization, avoiding large thoracotomy incisions.

Main Results:

Related Experiment Videos

  • Successful evacuation of disc material in five of seven cadaveric and two of three porcine disc spaces.
  • One instance of dural violation occurred.
  • One animal experienced an anesthetic complication, leading to mortality.

Conclusions:

  • VATS offers a viable method for thoracic discectomies via small thoracotomy incisions.
  • This minimally invasive technique may decrease morbidity, hospitalization, and costs.
  • Further research and instrumentation design are required for VATS to become a standard alternative.
