Video-assisted diagnostic thoracoscopy offers a high diagnostic yield with minimal risk for patients. However, nearly 26% of procedures require minithoracotomy for adequate tissue diagnosis, emphasizing surgeon experience.

Area of Science:

  • Thoracic Surgery
  • Diagnostic Procedures
  • Minimally Invasive Surgery

Background:

  • Video-assisted thoracoscopy (VAT) has seen increased adoption for thoracic diagnoses.
  • Detailed analysis of VAT's diagnostic yield and limitations is crucial for safe application.
  • Pre-procedure workups often fail to yield definitive diagnoses.

Purpose of the Study:

  • To evaluate the effectiveness of video-assisted diagnostic thoracoscopy.
  • To identify the limitations of this diagnostic technique.
  • To assess the diagnostic yield in relation to patient presentations.

Main Methods:

  • 102 diagnostic video-assisted thoracoscopic procedures were performed between July 1991 and December 1993.
  • Patients had various initial roentgenographic presentations including nodules, interstitial processes, and mediastinal tumors.

  • Procedures were classified as exclusive thoracoscopic biopsy (ETB) or supplementary thoracoscopic biopsy (STB) if minithoracotomy was needed.

    • Main Results:

    • 90.2% of pathology reports were conclusive, identifying 35 malignant and 67 benign tumors.
    • 74.5% of procedures were completed thoracoscopically (ETB), while 25.5% required minithoracotomy (STB).
    • Complications occurred in 3.9% of patients, with a 2.9% in-hospital mortality rate.

    Conclusions:

    • Diagnostic thoracoscopy demonstrates a high diagnostic yield and low risk.
    • A significant proportion (25.5%) of procedures necessitate minithoracotomy for definitive diagnosis.
    • Experienced thoracic surgeons are essential for successful diagnostic thoracoscopy, particularly when conversion to minithoracotomy is required.
