Summary
Percutaneous intrathoracic aspiration biopsy (PIAB) improved significantly in diagnostic accuracy from 71.6% to 84.9% between 1954-1980 and 1981-1985. This minimally invasive procedure offers effective diagnosis for pulmonary and mediastinal lesions.
Area of Science:
- Pulmonology
- Thoracic Surgery
- Diagnostic Imaging
Background:
- Percutaneous intrathoracic aspiration biopsy (PIAB) is a key diagnostic tool for pulmonary and mediastinal lesions.
- Assessing the evolution and effectiveness of PIAB over time is crucial for refining diagnostic strategies.
Purpose of the Study:
- To analyze the effectiveness and complication rates of percutaneous intrathoracic aspiration biopsies (PIAB).
- To compare the diagnostic yield of PIAB in different time periods and lesion characteristics.
Main Methods:
- Retrospective analysis of 617 PIAB procedures performed on 587 patients between 1954 and 1985.
- Comparison of procedure effectiveness in two distinct time intervals: 1954-1980 and 1981-1985.
Main Results:
- Overall diagnostic positivity increased significantly from 71.6% (1954-1980) to 84.9% (1981-1985), indicating technical improvements.
- Higher diagnostic positivity was observed for lesions measuring 2-3 cm in diameter.
- Complication rate was 7.8%; diffuse infiltrating lesions had lower positivity and a higher risk of pneumothorax.
Conclusions:
- PIAB technique advancements have led to statistically significant improvements in diagnostic accuracy.
- Lesion size and type influence PIAB effectiveness and complication risks.
- While effective, careful consideration of false-negative causes, such as inadequate sampling, is necessary.
