Ultrasonically activated shears (UAS) significantly reduce thyroidectomy operating time compared to conventional methods. This randomized trial confirms UAS safety and efficiency in thyroid surgery, with no increase in complications.

Area of Science:

  • Surgical Technology
  • Endocrine Surgery
  • Minimally Invasive Surgery

Background:

  • Ultrasonically activated shears (UAS) have demonstrated safety and speed in various surgical procedures, primarily in non-randomized studies.
  • Previous matched-pair studies suggested advantages of UAS in thyroidectomies.

Purpose of the Study:

  • To validate the benefits of ultrasonically activated shears (UAS) in thyroidectomies through a randomized controlled trial.
  • To compare the efficacy and safety of UAS versus conventional hemostatic methods in thyroid surgery.

Main Methods:

  • A randomized trial comparing ultrasonically activated shears (UAS) with conventional methods for thyroidectomies and lobectomies.
  • Patients underwent procedures for benign or malignant thyroid disease, with randomization stratified by surgeon experience and procedure type.

  • Key outcome measures included operative time, postoperative serum calcium levels, recurrent laryngeal nerve palsy, and bleeding volume.

    • Main Results:

    • The ultrasonically activated shears (UAS) group demonstrated a mean operating time of 99.1 minutes, compared to 134.9 minutes in the conventional group, yielding an average time saving of 35.8 minutes.
    • No significant differences in complications, including postoperative serum calcium levels, recurrent laryngeal nerve palsy, or bleeding, were observed between the UAS and conventional groups.
    • Statistical analysis indicated that the observed time savings would be even greater if surgeon experience imbalances were accounted for.

    Conclusions:

    • Ultrasonically activated shears (UAS) are a safe and effective device for performing total thyroidectomies and lobectomies.
    • The study confirms the utility of UAS in endocrine surgery, offering significant reductions in operative time without compromising patient safety.
