Overview

Meta-analysis reveals bronchus sign significantly improves diagnostic yield in robotic-assisted bronchoscopy biopsies.

Key Points

  • To determine the impact of bronchus sign presence on the diagnostic yield of robotic-assisted bronchoscopy in lung lesions.
  • Systematic review and meta-analysis of studies comparing bronchus sign presence in RAB biopsies.
  • Included 12 studies with a total of 2856 lesions.
  • Calculated summary odds ratios and performed sensitivity analyses to test results consistency.
  • Summary odds ratio of 1.91 for diagnostic yield in lesions with bronchus sign (95% CI [1.54, 2.36]; P<0.001).
  • Five studies demonstrated a significant association between bronchus sign presence and diagnostic yield.
  • No observed between-study variance or heterogeneity (τ2 = 0.00, I2 = 0%).
