The detection of pulmonary nodules (PNs) is likely to increase, especially with the release of the National Lung Screen Trials. When tissue diagnosis is desired, transthoracic needle aspiration (TTNA) is recommended. Several guided-bronchoscopy technologies have been developed to improve the yield of transbronchial biopsy for PN diagnosis: electromagnetic navigation bronchoscopy (ENB), virtual bronchoscopy (VB), radial endobronchial ultrasound (R-EBUS), ultrathin bronchoscope, and guide sheath. We undertook this meta-analysis to determine the overall diagnostic yield of guided bronchoscopy using one or a combination of the modalities described here. ⋯ This meta-analysis shows that the diagnostic yield of guided bronchoscopic techniques is better than that of traditional transbronchial biopsy. Although the yield remains lower than that of TTNA, the procedural risk is lower. Guided bronchoscopy may be an alternative or be complementary to TTNA for tissue sampling of PN, but further study is needed to determine its role in the evaluation of peripheral pulmonary lesions.

Review Meta Analysis
Intrapleural fibrinolytic therapy for treatment of adult parapneumonic effusions and empyemas: a systematic review and meta-analysis.
The purpose of our study was to conduct a systematic review and meta-analysis of all randomized controlled trials to date comparing fibrinolytics with placebo to clarify their current role in the management of parapneumonic effusions and empyemas. ⋯ This meta-analysis does reveal that fibrinolytic therapy is potentially beneficial in the management of parapneumonic effusions and empyemas in the adult population. Although there is insufficient evidence to support the routine use of this therapy for all parapneumonic effusions/empyemas, fibrinolytic therapy may be considered in patients with loculated pleural effusions, because it may prevent the need for surgical intervention. Further randomized controlled trials with adequate power are needed to definitively address the effect of fibrinolytics and the combination of fibrinolytics and deoxyribonuclease on the clinical outcomes outlined in this analysis in patients with parapneumonic effusions/empyemas.
