Summary

The harmonic scalpel offers a safe and effective alternative for peripheral lung biopsy, demonstrating a significantly shorter operation time compared to the standard endostapling technique without compromising safety or outcomes.

Area of Science:

  • Thoracic Surgery
  • Surgical Innovation

Background:

  • Video-assisted thoracoscopic surgery (VATS) is a common approach for lung biopsies.
  • Current techniques, such as endostaplers, are established but may have limitations.
  • Investigating novel tools like the harmonic scalpel can potentially improve efficiency and patient outcomes.

Purpose of the Study:

  • To evaluate the applicability and safety of the harmonic scalpel for pulmonary biopsies during VATS.
  • To compare the harmonic scalpel technique with the standard endostapler method regarding operative time, morbidity, and recovery.

Main Methods:

  • A randomized single-institute study compared the ultrasonic harmonic scalpel (n=20) with an endostapler (n=20) for pulmonary biopsies during VATS.
  • Key metrics included operative time, drainage duration, pleural fluid volume, complication rates, and in-hospital stay.

Main Results:

  • The harmonic scalpel group showed a significant reduction in average operative time (30.75 min vs. 46.9 min).
  • No significant differences were observed in drainage duration, pleural fluid volume, minor complication rates, or in-hospital stays between the groups.
  • Both methods demonstrated similar safety profiles.

Conclusions:

  • The harmonic scalpel is a safe alternative technique for peripheral lung biopsy.
  • This vibration-transmission method is not inferior to the standard endostapling technique.
  • The harmonic scalpel offers potential benefits in terms of reduced operative time for lung biopsies.
