Area of Science:

  • Veterinary Medicine
  • Surgical Pathology
  • Diagnostic Imaging

Background:

  • Accurate tissue sampling is crucial for diagnosing liver diseases in cattle.
  • Various small-gauge needles are available for veterinary liver biopsies.
  • Optimizing needle selection can improve sample yield and diagnostic quality.

Purpose of the Study:

  • To compare the efficacy of three commercially available biopsy needles for bovine liver aspiration.
  • To evaluate specimen size and diagnostic quality across different needle types.

Main Methods:

  • Aspiration biopsies were performed on disease-free bovine liver using Chiba, Sure-Cut, and PercuCut needles.
  • Needle performance was assessed based on specimen size and diagnostic quality.
  • Negative pressure was applied using a syringe for Chiba and Sure-Cut needles; PercuCut utilized internal negative pressure.

Main Results:

  • PercuCut and Chiba needles yielded significantly larger specimen sizes compared to the Sure-Cut needle.
  • No significant difference in sample size was observed between PercuCut and Chiba needles.
  • All biopsy samples obtained were of diagnostic quality.

Conclusions:

  • PercuCut and Chiba needles are more effective for obtaining larger bovine liver biopsy samples than Sure-Cut needles.
  • The choice of needle can impact specimen yield in veterinary liver biopsy procedures.
  • All tested needles are suitable for achieving diagnostic quality samples in bovine liver aspiration biopsies.
