Summary

Thoracoscopic biopsy of mediastinal masses offers a high diagnostic yield (93.6%) when percutaneous methods fail or are contraindicated. This minimally invasive surgical approach provides a safe alternative with a short hospital stay.

Area of Science:

  • Thoracic Surgery
  • Diagnostic Procedures
  • Oncology

Background:

  • Percutaneous biopsy of mediastinal masses has limitations, particularly for difficult locations or when immunological classification is needed.
  • Surgical biopsy remains essential for definitive diagnosis and treatment planning of mediastinal tumors.

Purpose of the Study:

  • To evaluate the efficacy and safety of thoracoscopic biopsy for mediastinal masses.
  • To compare thoracoscopy with traditional surgical biopsy methods.

Main Methods:

  • Thoracoscopic approach performed under general anesthesia with one-lung ventilation.
  • A series of 47 consecutive cases of mediastinal mass biopsies were analyzed.

Main Results:

  • Histological diagnosis was achieved in 93.6% (44 out of 47) of cases.

  • A single hemorrhagic complication (2.1%) necessitated thoracotomy.
  • The average postoperative hospital stay was 3.2 days.

    • Conclusions:

    • Thoracoscopy is the preferred method for mediastinal mass biopsy when percutaneous techniques are unsuccessful or not feasible.
    • Mediastinoscopy retains a role in the management of paratracheal lymph nodes.
