Tuberculous Pleural Effusion

There is controversy whether medical thoracoscopy is warranted when the suspicion for tuberculosis is high. In these cases, the diagnostic yield from closed-needle pleural biopsy is approximately 69%, with some studies reporting rates as high as 88%. [5] The current consensus is that medical thoracoscopy should be reserved for special circumstances, such as lysis of adhesions or more effective drainage of loculated effusions, as well as when larger quantities of tissue are needed for sensitivities.
