Pdf Summary

The study evaluated the safety and diagnostic yield of cryobiopsy for peripheral pulmonary lesions (PPL) using a 1.1 mm cryoprobe and guide sheath without fluoroscopy. Data from 400 cases were analyzed, and the diagnostic yields of forceps biopsy and cryobiopsy were compared. <br /><br />The results showed that the diagnostic yield of cryobiopsy was significantly higher than that of forceps biopsy, with a total diagnostic yield of 92.6% compared to 70.4%. Bleeding occurred in 70.6% of patients, but only 15.6% of cases were clinically significant. There were no cases of life-threatening bleeding. <br /><br />The study also highlighted the benefits of cryobiopsy, showing that as cryobiopsy is repeated, normal bronchial tissue is removed, providing a clearer image of the target lesion using radial EBUS. <br /><br />The use of a guide sheath during cryobiopsy was found to improve the diagnostic yield compared to forceps biopsy alone. The study concluded that cryobiopsy can be safely performed without the need for fluoroscopy guidance when using a guide sheath. <br /><br />Overall, the study suggests that cryobiopsy with a smaller cryoprobe and guide sheath is a valuable tool for diagnosing peripheral pulmonary lesions, offering higher diagnostic yields compared to forceps biopsy and a safe alternative to fluoroscopy-guided procedures.
