    Abrams needle pleural biopsies diagnosed 60% of effusions. Multiple biopsies improved diagnostic yield, especially for tumor and tuberculosis, with minimal complications.

    Area of Science:

    • Thoracic Medicine
    • Pathology
    • Interventional Pulmonology

    Background:

    • Pleural effusions require accurate diagnosis for effective management.
    • Conventional diagnostic methods for pleural effusions can be invasive and may have limitations.

    Purpose of the Study:

    • To evaluate the diagnostic yield of multiple pleural biopsies using the Abrams needle.
    • To assess the effectiveness of this technique in identifying malignancy and tuberculosis.

    Main Methods:

    • Fifty-five patients with pleural effusions underwent multiple (up to 10) pleural biopsies via a single aspiration site using an Abrams needle.
    • Pathological examination of all obtained biopsy samples.

    Main Results:

    • A definitive positive or suggestive diagnosis was achieved in 33 patients (60%).

  • Pathological abnormalities were often localized to a subset of the biopsies.
  • Biopsies were positive or suggestive for tumor in 72% (26/36) and for tuberculosis in 88% (7/8) of confirmed cases.
  • Minor complications included pneumothorax (4 patients) and surgical emphysema (2 patients).

    • Conclusions:

    • Multiple Abrams needle pleural biopsies are an effective method for diagnosing pleural effusions, particularly for malignancy and tuberculosis.
    • The diagnostic yield is significant, and the procedure is associated with a low rate of complications.
    • Optimizing the number of biopsies may be crucial, as abnormalities are frequently confined to a proportion of samples.
