Area of Science:

  • Pulmonology
  • Thoracic Surgery
  • Minimally Invasive Procedures

Background:

  • Pleural effusions require accurate diagnosis for effective management.
  • Conventional thoracoscopy can be limited in accessing certain effusion types.
  • Minimally invasive techniques aim to improve diagnostic yield and patient outcomes.

Purpose of the Study:

  • To evaluate the diagnostic efficacy and safety of minithoracoscopy using 3-mm instrumentation for pleural effusions.
  • To compare minithoracoscopy with conventional thoracoscopy in terms of visualization and diagnostic yield.
  • To assess patient tolerance and cosmetic outcomes of minithoracoscopy.

Main Methods:

  • A prospective study involving 30 patients with various types of pleural effusions (loculated, nonloculated, bilateral).

  • Utilized a double-entry site technique with 3-mm trocars for telescope and biopsy forceps.
  • Procedures performed under local anesthesia with mild sedation.

    • Main Results:

    • Minithoracoscopy achieved a high diagnostic yield of 93.4%.
    • Visualization quality was comparable to conventional thoracoscopy.
    • Procedures demonstrated good patient tolerance and favorable cosmetic results.

    Conclusions:

    • Minithoracoscopy using 3-mm instrumentation is a safe and effective diagnostic tool for pleural effusions.
    • The technique is suitable for both small loculated and larger nonloculated effusions.
    • It represents a valuable advancement for routine diagnostic thoracoscopy.
