Assessment of ultrasound-guided tru-cut needle pleural biopsy in the diagnosis of unexplained exudative pleural effusion compared to medical thoracoscopy

Background Ultrasound-guided needle biopsy (USGNB) allows for precise and immediate viewing of pleural lesions, effusions, and needle placement without ionizing radiation. This study aimed to assess the efficacy of US-guided tru-cut needle pleural biopsy in diagnosing unexplained exudative pleural effusion compared to medical thoracoscopy (MT), focusing on safety, accuracy, time, and cost of the treatment. Patients and methods This observational cross-sectional research was conducted on 40 patients over 18 years old, of both sexes, with unexplained exudative pleural effusion. The patients were randomly separated into two equal groups. The girst group is USGNB and the second group is MT. Results Group II exhibited substantially greater costs, sedation levels, procedure duration, biopsy site discomfort, surgical emphysema, lung expansion failure, and psychological distress compared to group I (P
