This study introduces coaxial biopsy needles for repeated tissue sampling. The innovative technique allows tract dilation without losing needle position, enabling multiple biopsies effectively.

Area of Science:

  • Medical Devices
  • Surgical Techniques
  • Oncology

Background:

  • Repeated tissue sampling is crucial for accurate diagnosis and treatment monitoring.
  • Existing biopsy methods can be invasive and may require repositioning, increasing patient discomfort and procedural time.
  • Minimally invasive techniques are sought to improve patient outcomes and diagnostic yield.

Purpose of the Study:

  • To present a novel coaxial biopsy needle system for serial tissue acquisition.
  • To evaluate the feasibility and efficacy of maintaining needle tract position during dilation.
  • To demonstrate the clinical utility of this technique in patients requiring multiple biopsies.

Main Methods:

  • A coaxial biopsy needle system with an outer, indwelling needle was utilized.

  • Transfer rods were employed to dilate the tissue tract from 23 to 16 gauge.
  • The system's ability to maintain the initial needle position during dilation was assessed.

    • Main Results:

    • The coaxial needle system successfully enabled repeated tissue sampling.
    • Tract dilation was achieved without compromising the initial needle placement.
    • The technique was successfully applied in a cohort of six patients.

    Conclusions:

    • The coaxial biopsy needle system offers a reliable method for obtaining serial tissue samples.
    • This technique minimizes the need for repositioning, potentially reducing complications and improving efficiency.
    • Further investigation is warranted to explore its broader clinical applications in various medical fields.
