Summary
PercuCut and Chiba needles provide larger bovine liver biopsy samples than Sure-Cut needles. All tested needles yielded diagnostic quality specimens, aiding veterinary diagnostics.
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.
