Diagnostic Value of Thoracoscopic Biopsy in Undiagnosed Pleural Effusion: An outcome based retrospective study in a tertiary cancer centre

Year: 2025
Type: article
Study design: Observational Study
Abstract: Background: Pleural biopsy can be performed via needle, thoracoscopy, or open surgery, with thoracoscopic biopsy emerging as a valuable tool for diagnosing pleural diseases. Video-assisted thoracoscopic surgery (VATS) offers direct visual assessment and targeted tissue sampling, with a diagnostic yield comparable to open biopsy while remaining minimally invasive. Despite extensive diagnostic efforts, the etiology of pleural effusion remains unclear in 20–25% of cases, necessitating more definitive diagnostic approaches. Objectives: This study aims to evaluate the diagnostic yield, accuracy, and clinical outcomes of thoracoscopic biopsy in patients with undiagnosed pleural effusion. Methods: Our study included patients who had undergone Video assisted thoracoscope biopsy (VATS) for undiagnosed pleural effusion at our center since 2015 to 2024. There was no follow up in our study. Data from 149 patients were taken and entered in Excel and analyzed via Statistical package for the social sciences (SPSS 27). Results: A total of 149 patients were included. The overall diagnostic yield of thoracoscopic biopsy was 98%, with malignancy being the most common diagnosis i.e.,75.3%. The procedure was well tolerated, with a complication seen in just 5 patients(3.36%) and no in-hospital mortality. Conclusion: Thoracoscopic biopsy is safe, highly effective diagnostic modality for undiagnosed pleural effusion. It has an advantage of having high accuracy and being minimally invasive. Thoracoscopic biopsy influence clinical management, leading to targeted treatment strategies.
