Summary
Ultrasonography-guided transbronchial lung biopsies improve diagnostic rates for thoracic wall lesions. Visualizing biopsy forceps via ultrasound enhances accuracy, especially for small or vague peripheral lung lesions.
Area of Science:
- Pulmonology
- Medical Imaging
- Interventional Pulmonology
Background:
- Diagnosing peripheral lung lesions adjacent to the thoracic wall can be challenging.
- Traditional methods like fluoroscopy may struggle with small or vague lesions.
Purpose of the Study:
- To evaluate the diagnostic yield of ultrasonography-guided transbronchial lung biopsies.
- To assess the impact of visualizing biopsy forceps on diagnostic accuracy.
Main Methods:
- Transbronchial lung biopsies and cytologic studies were performed on 39 patients with thoracic wall lesions.
- Procedures utilized ultrasonographic guidance from the body surface.
- Biopsy forceps visualization via thoracic echogram was assessed.
Main Results:
- A conclusive diagnostic rate of 88.5% was achieved when forceps were visualized within the lesion.
- When forceps were not visualized, the diagnostic rate was 76.9%.
- Ultrasonography-guided bronchofiberscopy confirmed forceps positioning in real-time.
Conclusions:
- Ultrasonography-guided biopsies are effective for lung lesions near the thoracic wall.
- Visualizing biopsy forceps ultrasonographically significantly increases diagnostic accuracy.
- This technique is valuable for peripheral lesions difficult to detect with fluoroscopy alone.
