Summary

A modified Abrams needle biopsy technique shows diagnostic sensitivity for tuberculous pleurisy comparable to standard Abrams and Cope methods. This improved technique for pleural biopsy offers equivalent diagnostic yield without increasing complications.

Area of Science:

  • Pulmonology
  • Thoracic Surgery
  • Infectious Diseases

Background:

  • Pleural biopsy is crucial for diagnosing pleural effusions.
  • Standard Abrams and Cope needle biopsy techniques have limitations.
  • A modified Abrams technique was developed to potentially improve diagnostic yield.

Purpose of the Study:

  • To compare the diagnostic sensitivity of a modified Abrams needle biopsy (A1) against the standard Abrams (A2) and Cope needle biopsy methods.
  • To evaluate the efficacy of a modified pleural biopsy technique.

Main Methods:

  • Retrospective chart analysis of 47 patients undergoing pleural biopsy.
  • Comparison of modified Abrams, standard Abrams, and Cope needle biopsy techniques.
  • Data collected included diagnostic sensitivity, sample size, number of biopsies, and complications.

Main Results:

  • Diagnostic sensitivity for tuberculous pleurisy: modified Abrams (82%), standard Abrams (71%), Cope (88%).
  • No significant difference in sensitivity between the modified Abrams and Cope methods (p > 0.3).
  • No significant differences observed in tissue sample size, number of biopsies, or complications among the techniques.

Conclusions:

  • The modified Abrams needle biopsy technique achieves diagnostic sensitivity for pleural tuberculosis equivalent to standard Abrams and Cope methods.
  • The modified technique offers a viable alternative for pleural biopsy without compromising diagnostic accuracy or safety.
