A novel CT-guided biopsy technique uses abdominal compression to displace organs, reducing needle track distance. This method achieved a 97% success rate in 29 patients for various node biopsies.

Area of Science:

  • Medical Imaging
  • Interventional Radiology
  • Surgical Technology

Background:

  • CT-guided biopsies are crucial for diagnosing various conditions.
  • Displacing abdominal organs can improve needle access and reduce complications.
  • Existing techniques may have limitations in organ displacement and needle track optimization.

Purpose of the Study:

  • To introduce and evaluate a CT-guided biopsy technique employing an abdominal compression device.
  • To assess the efficacy and safety of this novel compression system in clinical practice.

Main Methods:

  • Development and implementation of a CT-guided biopsy system with an abdominal compression device.
  • The device displaces digestive structures (colon, small bowel) from the needle path.

  • Procedure performed on 29 patients for mesenteric, retroperitoneal, or pelvic node biopsies.

    • Main Results:

    • The technique was successfully applied in 28 out of 29 patients (97% success rate).
    • Abdominal compression reduced the skin-to-lesion distance by approximately one-third.
    • The procedure was well-tolerated, with no increase in complication rates compared to conventional methods.

    Conclusions:

    • CT-guided biopsy with abdominal compression is a safe and effective technique.
    • This method facilitates biopsies in challenging locations by optimizing needle access.
    • The system is user-friendly, utilizes standard materials, and is well-tolerated by patients.
