ABSTRACT

Objective To investigate the diagnostic value and safety of thoracoscopy routine pleural biopsy combined with frozen biopsy for pleural effusion. Methods A retrospective analysis was made on the pathological diagnosis rate of pleural effusion. Results 120 cases in thoracoscopy, 103 cases were confirmed with routine biopsy specimens (85.8%), 16 cases found in the lesions with conventional clamp not satisfactory tissue specimens, combined with frozen cut obtained satisfactory specimens, the diagnostic accuracy rate of 16 cases of cryobiopsy was 100.0%, and the total diagnostic accuracy rate of medical thoracoscopy combined with pleural biopsy and cryobiopsy was 95.0%. There was significant difference between conventional biopsy and cryobiopsy (P < 0.05). Conclusion Medical thoracoscopy combined with pleural biopsy and cryobiopsy can achieve a higher rate of pathological diagnosis, and the complications are mild, so it is worthy of clinical promoting.
