Outcome Measures
Primary Outcomes (1)
Diagnostic yield
The proportion of all individuals undergoing the diagnostic procedure under evaluation in whom a specific diagnosis is established based on the consensus definition.
The day 7 after patients received CLE-assisted ultrasound-guided pleural biopsy.
Study Arms (2)
CLE-assisted ultrasound-guided pleural biopsy
EXPERIMENTALThe patients in this arm will receive the CLE-assisted ultrasound-guided pleural biopsy
Ultrasound-guided pleural biopsy
PLACEBO COMPARATORThe patients in this arm will receive the ultrasound-guided pleural biopsy
Interventions
Using the probe-based confocal laser endomicroscopy to detect the pleural, and ensure the biopsy location. Then, use the pleural biopsy tool to complete the pleural biopsy. The whole procession will under the ultrasound guidance.
Using ultrasound to detect the biopsy site and perform pleural biopsy.
