Description
Summary:Background The diagnostic role of medical thoracoscopy and image-guided pleural biopsy in patients with undiagnosed exudative pleural effusion has increased over the last few years. Objective The aim was to compare the efficacy and safety of medical thoracoscopy versus image-guided [ultrasound (US) and computed tomography] pleural biopsy in the diagnosis of pleural lesions. Patients and methods A total of 40 patients with undiagnosed pleural lesions were divided into two groups. After full investigations, pleural biopsies were taken by medical thoracoscopy and the image-guided technique in groups I and II, respectively. Results In group I, the results of 19 (95%) patients yielded a positive diagnosis, whereas in group II, the results of 17 (85%) patients yielded a positive diagnosis (where results were positive in 80% of US-guided biopsies and 90% in computed tomography-guided biopsies), with no significant difference in the diagnostic yield of the two groups. The US-guided biopsy showed significantly the least duration (P=0.001). Complications were significantly fewer in the image-guided biopsy group (P=0.008). The mean duration of hospital stay was significantly less in the image-guided group than in the medical thoracoscopy group (P=0.001). In conclusion, the overall diagnostic yield is comparably high for medical thoracoscopy and image-guided pleural biopsies, and both are complementary techniques used in different clinical situations. Each diagnostic procedure has its own advantages and disadvantages. Image-guided biopsy is less invasive and can be carried out as an outpatient procedure, whereas medical thoracoscopy provides diagnostic and therapeutic capabilities in one setting.
