Diagnostic value of closed percutaneous pleural biopsy vs pleuroscopy in suspected malignant pleural effusion or tuberculous pleurisy in a region with a high incidence of tuberculosis: a comparative, age-dependent study.
OBJECTIVE
To compare the value of closed percutaneous pleural biopsy versus pleuroscopy for diagnosis of undiagnosed exudative pleural effusion in an age-dependent manner.


METHODS
Prospective clinical study.


METHODS
University hospitals.


METHODS
Forty-nine consecutive patients with undiagnosed exudative pleural effusion following the initial clinical and paraclinical investigations, including bronchoscopy. Cases were divided into younger and older groups according to their ages.


METHODS
Closed pleural biopsy immediately followed by pleuroscopy with a flexible fiberoptic bronchoscope from the same incision site.


RESULTS
In the older age group, pleuroscopy was superior to closed pleural biopsy for the diagnosis of the underlying pleural disease (P = 0.0007), while they were almost equally diagnostic in the younger cases (P = 0.58).


CONCLUSIONS
For those patients with undiagnosed exudative pleural effusion who are older than 50 years of age, pleuroscopy could be chosen as the first procedure of choice as compared to closed pleural biopsy if malignant pleural effusion is suspected.
