Diagnostic Accuracy and Safety of Nonsurgical Biopsy for Diagnosing Pulmonary Ground-Glass Opacities: A Systematic Review and Meta-Analysis

Nonsurgical biopsy for diagnosing GGOs shows high sensitivity and specificity with an acceptably low risk of complications. However, negative biopsy results are unreliable in excluding malignancy, necessitating resampling or subsequent follow-up. The applicability of our study is limited due to significant heterogeneity, indirect comparisons, and the paucity of data on bronchoscopic approaches, restricting the generalizability of our findings to patients requiring transbronchial biopsies.
