Thoracoscopic discectomy offers reduced morbidity and shorter hospital stays compared to thoracotomy. However, its complex learning curve may limit its widespread adoption by surgeons.

Area of Science:

  • Neurosurgery
  • Minimally Invasive Spine Surgery

Background:

  • Thoracoscopic discectomy is a minimally invasive alternative to traditional open spine surgeries.
  • Previous comparisons between thoracoscopic discectomy and thoracotomy have been difficult to interpret.

Purpose of the Study:

  • To prospectively compare the outcomes of thoracoscopic discectomy with thoracotomy.

Main Methods:

  • A prospective nonrandomized study compared 36 patients undergoing thoracoscopic discectomy with 8 patients undergoing thoracotomy.
  • Data collected included operative time, blood loss, chest tube duration, narcotic use, and hospital length of stay.
  • Longer-term follow-up assessed pain and neurological function using Frankel grades.

Main Results:

Related Experiment Videos

  • Thoracoscopic discectomy showed significantly shorter operative times, less blood loss, reduced narcotic use, and shorter hospital stays.
  • 75% of patients with radiculopathy improved, with no worsening of pain.
  • Myelopathic patients in the thoracoscopic group improved by two Frankel grades versus one in the thoracotomy group.
  • Complication rates were 31% for thoracoscopic discectomy versus over 100% for thoracotomy.

    • Conclusions:

    • Thoracoscopic discectomy demonstrates reduced morbidity and improved patient outcomes compared to thoracotomy.
    • The steep learning curve and unfamiliar techniques present challenges for surgeon adoption.
    • Traditional costotransversectomy, transpedicular, and thoracotomy approaches remain viable for experienced surgeons.
