      The demonstration of the possibility of diagnosing changes located in the parietal pleura by means of cryo probe guided by videopleuroscopy.

      The study consisted of five patients with lesions of the parietal pleura and accumulation of fluid in the pleural space suspected of neoplastic disease. The previous diagnostic procedures did not confirm the etiology of the hydrothorax, therefore, the patients were qualified for the videopleuroscopy under local anesthesia and sedation. The ultrasound examination confirmed the presence of the pleural fluid and videotrocar was introduced into the pleural cavity. The videopleuroscope was inserted into the pleural cavity, the fluid was removed and the parietal lesions were visualised. The 1,9 mm cryo probe was introduced through the 2 mm working channel of the videopleuroscope and samples of the parietal pleura were taken. The sampling procedure was repeated with standard forceps. Talc slurry administration and drainage of the pleural cavity were performed eventually. All the patient were discharged a few days after the procedure.

      Mesothelioma was confirmed in one case, primary lung adenocarcinoma in one case, metastatic adenocarcinoma in one case, Ewing sarcoma in one case and chronic pleuritis in one case. Histology samples taken with the cryo probe were much bigger and of better quality than the samples taken by the forceps.

      The cryo probe guided by the videopleuroscopy is an effective and safe procedure regarding diagnosing pleural lesions suspected of the neoplastic disease. The cryo probe provides very good samples of the parietal pleura for the pathologic and immunohistochemistry evaluation
