Summary
Preoperative barium marking using virtual bronchoscopic navigation precisely located small lung lesions for thoracoscopic surgery. This minimally invasive technique accurately guided resection, preventing complications and improving patient outcomes.
Area of Science:
- Pulmonology
- Thoracic Surgery
- Medical Imaging
Background:
- Accurate localization of small peripheral pulmonary lesions is crucial for successful thoracoscopic surgery.
- Traditional methods may lack precision for deep-seated or subtle nodules.
Observation:
- A 77-year-old woman with a 9x7 mm ground-glass opacity in the right lower lobe underwent preoperative localization.
- Virtual bronchoscopic navigation guided an ultrathin bronchoscope to the lesion site (B8a, B6b).
- Barium was infused via a special catheter, creating a visible marker.
Findings:
- Barium marking allowed clear intraoperative identification using radiographic fluoroscopy.
- The technique facilitated precise determination of the resection area.
- Pathological examination confirmed atypical adenomatous hyperplasia.
Implications:
- This barium marking method offers a safe and effective approach for preoperative localization of small peripheral lung lesions.
- It enhances the precision of thoracoscopic resection, potentially reducing recurrence and improving patient prognosis.
- The technique is time-efficient and adaptable for marking multiple lesions.
