DIAGNOSTIC VALUE OF THORACOSCOPIC PLEURAL BIOPSY FOR PLEURISY UNDER LOCAL ANAESTHESIA

ANZ JOURNAL OF SURGERY, Issue 8 2006
Motoki Sakuraba
Background: We find pleural effusion in clinical practice frequently. However, it is difficult to make a diagnosis definitively by thoracocentesis or closed pleural biopsy. We directly examine the thoracic cavity by thoracoscopy under local anaesthesia, carry out pleural biopsy and make a definitive pathological diagnosis in pleurisy. Method: A retrospective study of 138 patients who had been diagnosed by thoracoscopy in our hospital was carried out between January 1995 and January 2005. Results: The patients were 114 men and 24 women, ranging in age from 21 to 85 years, with a mean of 59 years. The right side was involved in 83 patients and the left side in 55. The operations took 11,145 min, with a mean of 46 min. Thoracoscopy directly without thoracocenteses was carried out in 28 of 138 patients. Lung cancer with pleural dissemination was diagnosed in 27, malignant pleural mesothelioma in 10, tuberculous pleurisy in 32, non-specific pleurisy in 58, other tumour in 2 and pyothorax in 9 patients. The overall diagnostic efficacy was 97.1% (134/138). The diagnostic efficacy in the cases of carcinoma was 92.6% (25/27), in malignant pleural mesothelioma it was 100% (10/10) and in tuberculosis it was 93.8% (30/32). No major complications occurred during the examination. Conclusion: Pleural biopsy by thoracoscopy under local anaesthesia should be actively carried out in patients with pleurisy, because the technique has a high diagnostic rate and can be easily and safely carried out.

A comparative study of pleurodesis using talc slurry and bleomycin in the management of malignant pleural effusions

RESPIROLOGY, Issue 2 2000
Kian Chung Ong
Objective: Differing success rates of various pleurodesis agents have been reported in the management of malignant pleural effusions. A randomized clinical trial was conducted to compare the efficacy of two commonly used agents, talc and bleomycin, for the pleurodesis of malignant pleural effusions. Methodology: Inclusion in the study required proof of a malignant pleural effusion by fluid cytology or pleural biopsy. Exclusion criteria included trapped lung, loculated effusions, recurrent effusions and life expectancy < 1 month. Five grams of talc or 1 unit per kilogram bodyweight of bleomycin mixed in 150 mL of normal saline was administered via tube thoracostomy after complete drainage of the pleural effusion in each patient. Treatment success was defined as the absence of recurrent pleural effusion on the chest radiograph 1 month after pleurodesis. Results: Treatment success was achieved in 16 out of 18 patients (89%) in the talc slurry group versus 14 out of 20 patients (70%) in the bleomycin group (P = 0.168). Fever and pain were the only side-effects of pleurodesis in both groups. Conclusion: These results indicate that talc slurry is as effective as bleomycin in preventing early recurrence of malignant pleural effusions. Pleurodesis with talc instead of bleomycin can result in significant cost savings. [source]

Pleural amyloidosis in a patient with intractable pleural effusion and multiple myeloma

RESPIROLOGY, Issue 1 2000
Toshitaka Maeno
Abstract: Pleural involvement of systemic amyloidosis has been rarely reported. We report a case with multiple myeloma presenting an intractable right pleural effusion, in which pleural amyloidosis was diagnosed through pleural biopsy using a Cope needle. The diagnosis of pleural amyloidosis is important, because its refractory pleural effusion should be treated with pleurodesis. Since closed pleural biopsy using a Cope needle is much less invasive than thoracoscopy, the former should be attempted first whenever pleural amyloidosis is suspected. [source]

Enzyme-linked immunospot assay for interferon-gamma in the diagnosis of tuberculous pleurisy

CLINICAL MICROBIOLOGY AND INFECTION, Issue 2 2009
L.-N. Lee
Abstract Patients presenting with pleural effusion of undetermined aetiology were prospectively enrolled, and an enzyme-linked immunospot (ELISPOT) assay on pleural fluid and peripheral blood was performed. Forty patients were studied, including 19 with culture- or biopsy-confirmed (n = 15) or clinically compatible (n = 4) tuberculous pleurisy, and 21 with pleural effusions due to non-tuberculous causes. The sensitivity, specificity and positive and negative predictive values of the assay were 94.7%, 85.7%, 85.7% and 94.7%, respectively, on pleural fluid, and 77.8%, 90.5%, 87.5% and 82.6%, respectively, on blood. Antigen-specific, interferon-gamma-secreting T-cells were concentrated eight to ten times in pleural fluid as compared with blood. Among the seven patients not suitable for pleural biopsy and three patients whose biopsy results were non-diagnostic, nine had positive ELISPOT result with pleural fluid. The ELISPOT assay for interferon-gamma can accurately diagnose tuberculous pleurisy and is helpful for patients not suitable for pleural biopsy and those whose biopsy results are non-diagnostic.
