[The diagnostic value of thoracoscopy in pleural mesothelioma]
Objective:
To analyse the diagnostic value of thoracoscopy in pleural mesothelioma.
Methods:
The image features under thoracoscopy and the histology of 32 patients with pleural mesothelioma were reported. And the diagnostic rate of thoracoscopy was compared with those of chest X-ray, CT, effusion fluid cytology, tomography and the percutaneous needle pleural biopsy.
Results:
The diagnostic rate of thoracoscopy in pleural mesothelioma was 100%, and the histologic subtypes were the benign fibrous (5 cases), epithelial (9 cases), fibrosarcoma (12 cases) and the mixed (6 cases). The positive rates of chest X-ray, tomography, pleurography, CT, effusion fluid cytology and the percutaneous needle pleural biopsy were 13%, 33%, 38%, 61%, 15% and 24% respectively.
Conclusion:
Thoracoscopy was found to be the best method for diagnosing pleural mesothelioma, by which all pleural lesions could be observed and biopsied directly.
