The free-hand percutaneous ethanol injection (PEI) is a cost-effective method for treating autonomously functioning thyroid nodules. This technique offers advantages in safety and cost compared to ultrasound-guided PEI.

Area of Science:

  • Endocrinology
  • Minimally Invasive Procedures
  • Medical Imaging

Background:

  • Autonomously functioning thyroid nodules require effective treatment options.
  • Percutaneous ethanol injection (PEI) is a recognized treatment modality.
  • Comparison between free-hand and ultrasound-guided PEI techniques is essential for clinical practice.

Purpose of the Study:

  • To describe and evaluate the free-hand percutaneous ethanol injection (PEI) technique for autonomously functioning thyroid nodules.
  • To compare the free-hand PEI technique with the ultrasound-guided PEI technique.
  • To report the results, advantages, and disadvantages of the free-hand PEI technique.

Main Methods:

  • A free-hand percutaneous ethanol injection (PEI) technique was employed in 25 patients from January 1990 to October 1992.

  • Ultrasound examinations were used to guide needle insertion without a guiding device.
  • The technique involved aiming the needle at the nodule and inserting it during ultrasound, allowing for adjustments to probe movement.

    • Main Results:

    • The free-hand PEI technique allows for continuous monitoring of critical structures and immediate cessation of injection if seepage occurs.
    • This method is inexpensive, utilizing standard ultrasound probes and simple sterile wrapping to prevent contamination.
    • The ultrasound-guided technique, while rapid and safe for needle placement, limits probe movement and visualization of ethanol spread.

    Conclusions:

    • The free-hand PEI technique is a safe, cost-effective, and viable alternative for treating autonomously functioning thyroid nodules.
    • It offers greater control over ethanol distribution and prevention of complications compared to the ultrasound-guided method.
    • Further studies may be warranted to fully establish its long-term efficacy and patient outcomes.
