Summary
High-speed air drill lung biopsy is a safe and simple procedure for diagnosing lung lesions. While diagnostic yield was 49%, this trephine lung biopsy technique is valuable for diffuse and localized lung conditions.
Area of Science:
- Pulmonology
- Thoracic Surgery
- Interventional Radiology
Background:
- Lung biopsies are crucial for diagnosing diffuse and localized lung lesions.
- Assessing the efficacy and safety of minimally invasive biopsy techniques is essential.
Purpose of the Study:
- To report the results of high-speed air drill lung biopsy over 38 months.
- To evaluate the diagnostic yield, safety, and effectiveness of trephine lung biopsy.
Main Methods:
- A retrospective analysis of 38 months of high-speed air drill lung biopsy procedures in Addis Ababa.
- Inclusion of 19 male and 20 female patients, plus 8 postmortem lung tissue specimens.
- Comparison of biopsy techniques, including lateral decubitus versus sitting positions for diffuse lesions.
Main Results:
- The overall diagnostic yield of trephine lung biopsy was 49%.
- Diffuse pulmonary infiltrates were present in 42 patients, localized lesions in six.
- Biopsy in the lateral decubitus position yielded larger specimens for diffuse lesions compared to the sitting position.
Conclusions:
- Trephine lung biopsy is a safe and simple procedure with a role in investigating lung lesions.
- Caution is advised in patients with chronic cor pulmonale due to the risk of haemoptysis.
- Post-biopsy chest radiography is recommended only when clinically indicated.
