When the latter isn’t successful, and the patient is in a poor performance status, applying tube thoracostomy is the usual routine, to avoid conversion to thoracotomy and open decortication. Tube thoracostomy, however, is associated with complications necessitating further surgery, needs long term follow up and also entails quality of life distorting issues. To overcome these disadvantages, we instead inserted a PleurX® indwelling pleural catheter in four patients in the above situation. The method brought success (lung re-expansion and complete or partial pleurodesis) without the need for further surgery or quality of life problems in either patient. Although the use of the indwelling pleural catheter in infected pleural space is not recommended by manufacturers, we noted no complications.展开更多

Objective: To demonstrate clinical features and outcome of pleural effusion. Methods: Prospective descriptive study was conducted involving 110 patients with pleural effusion admitted to a resource limited hospital in Ethiopia. Results: Males and females were almost equally represented. Cough, fever and weight loss were prominent presenting symptoms accounting 90, 77.3 and 77.3 percent respectively. Right side effusion was the common presentation 50 (45.5%). Forty (37.4%) patients had HIV infection among 107 tested. Tuberculosis was the commonest cause 78 (70.9%) followed by parapneumonic effusion 36 (32.7%) and empyema 27 (24.5%). Malignant pleural effusion was detected only in one patient. Eighty one (73.6%) improved from their illness and 7 (6.4%) died. Lympocytic pleural effusion found to be associated with tuberculosis (OR = 3.942 (1.527 - 10.179), P = 0.005. There were no associations between HIV infection, anemia, elevated ESR and side of pleural effusion with tuberculosis. Conclusion: Tuberculosis was the leading cause of pleural effusion in our setup even though etiologic diagnosis was difficult. Strengthening the laboratory and pathology services in the area is strongly recommended.展开更多
