First 50 Cases with the ION Robotic-Assisted Navigational Bronchoscopy System in Routine Clinical Use in Germany: The...

Area of Science:

• Pulmonology
• Thoracic Surgery
• Medical Technology

Background:

• Diagnostic work-up of small peripheral pulmonary nodules (PPNs) is crucial due to lung cancer screening programs.
• Robotic-assisted navigational bronchoscopy (RNB) systems, like the ION system, are emerging innovations.
• This study evaluates the initial outcomes of the ION system in Germany.

Purpose of the Study:

• To present the outcomes of the first 50 patients evaluated with the ION RNB system.
• To assess the diagnostic yield and accuracy of the ION system for PPNs.
• To identify factors influencing diagnostic success.

Main Methods:

• Retrospective, single-center analysis of 50 consecutive patients.
• Utilized the ION robotic-assisted navigational bronchoscopy (RNB) system.
• Included evaluation of nodule location, size, and type, with adjuncts like cone beam CT (CBCT) and radial endobronchial ultrasound (rEBUS).

Main Results:

• The ION system was used to evaluate 50 patients with PPNs located primarily in the peripheral lung (74%).
• Overall diagnostic yield was 78%, increasing to over 90% when using CBCT and formalin-fixed paraffin-embedded histology.
• Nodule characteristics included mean size of 1.64 cm, with 84% solid, 4% subsolid, and 12% GGOs.

Conclusions:

• Initial clinical experience with the ION-RNB system in Germany is encouraging.
• The system demonstrates high diagnostic accuracy for peripheral pulmonary lesions, especially with advanced imaging like CBCT.
• Optimizing diagnostic pathways requires careful consideration of imaging techniques and histopathological processing methods.
