Area of Science:

  • Hepatology
  • Medical Devices
  • Diagnostic Procedures

Background:

  • Traditional liver biopsy needles present economic challenges, particularly in developing nations with high liver disease prevalence.
  • Disposable needles contribute to the financial burden associated with liver disease diagnosis and management.

Purpose of the Study:

  • To evaluate the efficacy of a suction aspiration technique using a disposable syringe and an 18-gauge needle.
  • To compare this technique against the Vim-Silverman needle for obtaining liver tissue samples.
  • To assess diagnostic yield and tissue adequacy across different liver disease etiologies.

Main Methods:

  • A comparative study involving 60 patients undergoing liver biopsy with each technique.
  • Quantitative assessment of biopsy tissue size obtained by both methods.

Related Experiment Videos

  • Qualitative assessment of diagnostic adequacy for each tissue sample.

    • Main Results:

    • Suction aspiration produced significantly larger mean tissue samples (11.2 mm) compared to the Vim-Silverman technique (6.3 mm) (p=0.001).
    • Inadequate tissue for diagnosis occurred in fewer patients with suction aspiration (3) versus Vim-Silverman (10).
    • The difference in inadequate samples was not statistically significant (p=ns).

    Conclusions:

    • Suction aspiration liver biopsy with a disposable syringe and 18-gauge needle is a viable and effective procedure.
    • This technique provides satisfactory liver tissue for diagnosis, potentially reducing costs.
    • It presents a practical alternative for liver biopsy in resource-limited settings.
