Summary
Augmented fluoroscopic bronchoscopy (AFB) effectively localizes small pulmonary nodules using dye or microcoils. This safe and reproducible technique aids in guiding minimally invasive resections, improving patient outcomes.
Area of Science:
- Pulmonology
- Interventional Radiology
- Thoracic Surgery
Background:
- Small pulmonary nodules pose localization challenges for surgical resection.
- Accurate pre-operative localization is crucial for minimally invasive thoracic procedures.
Purpose of the Study:
- To evaluate the efficacy and safety of augmented fluoroscopic bronchoscopy (AFB) for localizing small pulmonary nodules.
- To analyze procedural details and outcomes of 100 consecutive AFB cases.
Main Methods:
- Retrospective analysis of prospectively collected data from 100 patients with 124 small lung nodules.
- AFB localization using dye marking and/or microcoil placement, followed by thoracoscopic resection within 3 days.
- Procedures performed in a cone-beam CT examination room.
Main Results:
- Successful AFB localization in 94% of cases (94/100).
- Mean nodule size 9.7 mm; mean distance from pleura 18.6 mm.
- High success rate for marker-guided resection (91/94), with short postoperative stays (mean 4.2 days).
Conclusions:
- Augmented fluoroscopic bronchoscopy (AFB) is a safe and reproducible method for localizing small pulmonary nodules.
- AFB offers flexibility with various localization strategies suitable for different nodule characteristics.
- The technique facilitates successful marker-guided resection, supporting its role in thoracic surgery.
