Pdf Summary

This study focused on evaluating the safety and effectiveness of cryobiopsy for peripheral pulmonary lesions (PPL) without the use of fluoroscopy. Cryobiopsy is a procedure that enhances the diagnostic yield of PPL, and it is typically performed with a guide sheath and fluoroscopy guidance. However, there have been limited studies on cryobiopsy without fluoroscopy. <br /><br />The study analyzed data from 400 cases of cryobiopsy for PPL at Chungnam National University Hospital. The diagnostic yield of cryobiopsy was compared to forceps biopsy, with cryobiopsy showing a significantly higher diagnostic yield of 85.7% compared to 70.4% for forceps biopsy (p<0.001). <br /><br />Bleeding was a common complication, occurring in 70.6% of patients. However, only 15.6% of cases experienced clinically significant bleeding, and there were no cases of life-threatening bleeding. <br /><br />The study concludes that using a guide sheath during cryobiopsy improves the diagnostic yield compared to forceps biopsy alone. Additionally, cryobiopsy can be safely performed without the need for fluoroscopy guidance. <br /><br />Overall, this study provides valuable insights into the use of cryobiopsy for PPL and suggests that it can be an effective and safe alternative to conventional biopsy methods.
