New research underscores the growing adoption of cone-beam computed tomography (CBCT)-guided bronchoscopy in detecting peripheral pulmonary lesions (PPLs). A comprehensive meta-analysis encompassing data from 1,769 patients across 23 studies reveals significant advancements in diagnostic precision and patient safety associated with this technique.
CBCT-Guided Bronchoscopy Yields High Diagnostic Accuracy
The analysis highlights an impressive overall diagnostic yield (DY) of 80.2% for CBCT-guided bronchoscopy in identifying PPLs. Notably, when integrated with robotic-assisted navigation, the DY peaks at 87.5%, showcasing the enhanced accuracy of combined technological approaches. Even without additional navigation tools, CBCT alone maintains a robust DY of 78.9%, affirming its standalone efficacy in clinical settings.
Lesion Characteristics Influence Diagnostic Success
Further examination reveals that specific lesion attributes significantly impact diagnostic outcomes. Lesions exceeding 20 mm in size, exhibiting a bronchus sign, and possessing solid characteristics are more likely to be accurately diagnosed using CBCT-guided bronchoscopy. These factors contribute to higher odds of successful detection, emphasizing the importance of lesion profiling in procedural planning.
• Combining CBCT with robotic assistance substantially increases diagnostic yield.
• Larger, bronchus-sign-positive, and solid lesions enhance the likelihood of accurate diagnosis.
• The adverse event rate remains low at 2.3%, highlighting the procedure’s safety.
The findings affirm that CBCT-guided bronchoscopy stands as a reliable and safe method for diagnosing peripheral lung lesions. Clinicians can leverage this technology to improve diagnostic workflows, particularly for patients presenting with larger, clearly defined lesions. Its integration with advanced navigation systems like robotic-assisted bronchoscopy could set a new standard in respiratory diagnostics, potentially leading to earlier and more accurate detection of pulmonary conditions.
