Lung volume reduction surgery (LVRS) using stapling is more effective and safer than laser resection for diffuse emphysema. Further research is needed before routine application of LVRS.

Area of Science:

  • Pulmonary Medicine
  • Thoracic Surgery
  • Respiratory Disease Research

Background:

  • Lung volume reduction surgery (LVRS) is a re-emerging treatment for severe diffuse emphysema.
  • Evidence from randomized controlled trials is crucial for optimizing LVRS.

Purpose of the Study:

  • To evaluate the effectiveness of LVRS through randomized controlled trials.
  • To identify optimal surgical techniques and patient selection criteria for LVRS.
  • To determine which patients benefit most and which should avoid LVRS.

Main Methods:

  • Searched Cochrane Airways Group COPD register and Cochrane Controlled Clinical Trials Register for relevant randomized controlled trials.
  • Included trials on safety and efficacy of LVRS for diffuse emphysema, excluding giant or bullous emphysema.

  • Two independent reviewers assessed trial eligibility and extracted data.

    • Main Results:

    • Only one randomized trial was identified, comparing stapled thoracoscopic lung reduction with laser reduction in 72 patients.
    • Stapling showed significantly greater improvement in FEV1 and FVC at six months, reduced supplemental oxygen need, and improved quality of life.
    • The stapling group had significantly lower rates of delayed pneumothorax compared to the laser group.

    Conclusions:

    • No randomized controlled trial evidence currently supports LVRS efficacy compared to optimal conservative medical therapy for diffuse emphysema.
    • Stapling appears more effective and has a lower complication rate than laser resection for LVRS.
    • Routine LVRS application should be deferred until results from ongoing large trials are available.
