Summary
This summary is machine-generated.

The STARCUT aspiration-type needle yielded the heaviest specimens among six semi-automatic cutting biopsy needles. However, aspiration did not significantly increase specimen weight compared to non-aspiration techniques with this needle.

Area of Science:

  • Medical Devices
  • Surgical Pathology
  • Biopsy Techniques

Background:

  • Semi-automatic cutting biopsy needles are crucial for tissue sampling.
  • Evaluating needle performance, including specimen yield, is essential for optimizing diagnostic accuracy.
  • Variations in needle design, such as aspiration capability, may influence specimen weight.

Purpose of the Study:

  • To compare the specimen weight differences among six types of semi-automatic cutting biopsy needles.
  • To evaluate the impact of aspiration on specimen weight for a specific needle type.

Main Methods:

  • Six semi-automatic cutting biopsy needles (18- and 20-gauge) were tested, including one aspiration-type (STARCUT) and five non-aspiration types.
  • Four biopsies were performed with each needle on excised bovine liver.
  • The STARCUT needle was tested with and without aspiration.

Main Results:

  • The STARCUT aspiration-type needle produced significantly heavier specimens compared to five non-aspiration needles (P < 0.05).
  • Significant differences in specimen weight were observed among all tested 18- and 20-gauge needles (P < 0.001).
  • No significant difference in specimen weight was found between aspiration and non-aspiration biopsies using the STARCUT needle for both 18-gauge (P = 0.342) and 20-gauge (P = 0.886) needles.

Conclusions:

  • While the STARCUT aspiration-type needle provided the heaviest specimens, aspiration itself did not significantly enhance specimen weight.
  • Significant variability exists in specimen weight across different semi-automatic cutting biopsy needles.
  • Needle selection may influence specimen yield, but the role of aspiration requires further investigation.
