Thoracoscopic discectomy offers better surgical outcomes for thoracic disc herniations compared to thoracotomy. This minimally invasive approach reduces pain, hospital stay, and complications, improving neurological function.

Area of Science:

  • Neurosurgery
  • Thoracic Surgery
  • Minimally Invasive Procedures

Background:

  • Thoracic disc herniations can lead to significant neurological deficits.
  • Surgical intervention is often required to decompress the spinal cord.
  • Traditional thoracotomy approaches carry substantial morbidity.

Purpose of the Study:

  • To prospectively evaluate surgical and neurological outcomes of thoracic disc surgery.
  • To compare thoracoscopic discectomy with thoracotomy for thoracic disc herniation.

Main Methods:

  • Prospective data collection on operating time, blood loss, chest tube duration, narcotic use, and length of hospital stay (LOS).
  • Assessment of long-term neurological function using Frankel grades and pain-related symptoms.
  • Comparison of outcomes between thoracoscopic discectomy and thoracotomy groups.

Main Results:

  • Thoracoscopic discectomy showed a 2-Frankel grade improvement in myelopathy patients versus 1 grade for thoracotomy.
  • Patients undergoing thoracotomy had significantly worse preoperative conditions.
  • No patients experienced worsened pain; radiculopathy pain improved by 75% in the thoracoscopic group.

Conclusions:

  • Thoracoscopic discectomy provides acceptable surgical results for thoracic disc herniation.
  • This technique offers advantages including reduced postoperative pain, morbidity, and LOS.
  • Minimally invasive thoracoscopic discectomy is a favorable surgical option.
