Objective To explore the clinical value of pleura biopsy and partial pleura cryobiopsy via electronic bronchoscope in diagnosis of unknown exudative pleural effusion.
Methods Diagnostic results of 563 patients with unknown exudative pleural effusion were analyzed retrospectively. Bronchoscope and routine pleura biopsy were performed in 187 patients. Bronchoscope and routine pleura biopsy plus partial pleura cryobiopsy were performed in 376 patients. Pathological positive rates of the two groups were compared.
Results In the 187 patients examined by bronchoscope and routine pleura biopsy from 2006 to 2008, 161 patients obtained pathological positive results ( 86.1% ) . In the 376 patients examined by bronchoscope and routine pleura biopsy plus partial pleura cryobiopsy from 2009 to 2012, 354 patients acquired pathological diagnosis ( 94.1% ) . There was significant difference between the two groups ( P lt; 0.05) . The main complications were bleeding and local chest pain, and they can be controlled easily.
Conclusions Electronic bronchoscope and pleura biopsy can obtain high detection rate of nearly 90% in diagnosis of unknown exudative pleural effusion especially when combined with cryobiopsy of partial pleura. Electronic bronchoscope combined with pleura biopsy or cryobiopsy is an alternative in clinical settings when thoracoscope is unavailable.
