Summary
Robotic bronchoscopy platforms Ion and Monarch show similar diagnostic yield for peripheral pulmonary nodules. Nodule size and bronchus sign predict procedural success, aiding patient selection for robotic-assisted bronchoscopy.
Area of Science:
- Pulmonology
- Medical Devices
- Diagnostic Imaging
Background:
- Robotic-assisted bronchoscopy is increasingly used for peripheral pulmonary nodule sampling.
- Comparative performance data between the Ion and Monarch robotic platforms are limited.
Purpose of the Study:
- To compare the diagnostic yield and safety of the Ion and Monarch robotic bronchoscopy platforms.
- To identify radiographic features predicting procedural success in nodule sampling.
Main Methods:
- Retrospective, 2-site cohort study of 217 adult patients undergoing robotic-assisted bronchoscopy.
- Procedures performed using either Ion or Monarch platform with 2D fluoroscopy.
- Logistic regression and lasso regression models analyzed diagnostic yield and predictive factors.
Main Results:
- No significant difference in diagnostic yield between Ion and Monarch platforms observed.
- Nodule size (OR: 1.42) and presence of a bronchus sign (OR: 2.14) were significant predictors of diagnostic yield.
- Median nodule size was 1.4 cm, similar across both platforms.
Conclusions:
- Both Ion and Monarch platforms demonstrate potential for sampling small peripheral nodules.
- Neither platform showed a superior procedural yield in this study.
- Nodule size and bronchus sign are valuable for preprocedural patient selection.
