CHEST 2023 On Demand Pass-Cardiothoracic Surgery: Cutting Edge

Video Transcription

Video Summary

The study presented aimed to evaluate the use of shape-sensing robotic ion bronchoscopy for diagnosing and reaching target lesions. The study included a retrospective review of 239 cases conducted at a single institution. The overall diagnostic yield was 78% and the success rate of reaching the target lesions was 97%. Factors associated with improved diagnostic yield included larger lesion size and the presence of the bronchus sign. Eccentric lesions were associated with decreased odds of achieving a diagnosis. Cone beam CT was used as an adjunctive imaging technique and was found to be helpful for visualization of eccentric lesions and for adjusting the target for biopsy. Adverse events were reported in 1.7% of cases, including pneumothorax and bleeding. Non-diagnostic cases were further investigated for clinical diagnosis or underwent surgical biopsy. In conclusion, the study found that shape-sensing robotic ion bronchoscopy had a high diagnostic yield and success rate in reaching target lesions. Factors such as lesion size, eccentricity, and the presence of the bronchus sign were associated with improved diagnostic yield. Further investigation is needed to assess the effectiveness of cone beam CT in improving diagnostic rates. Additionally, the use of cryobiopsy instead of forceps biopsy showed promise in obtaining better tissue samples, especially for eccentric lesions.
