Area of Science:

  • Thoracic Surgery
  • Pulmonary Medicine
  • Surgical Innovation

Background:

  • Accurate identification of intersegmental planes is crucial for complete lung segmentectomy.
  • Conventional methods like residual segment inflation can be difficult and time-consuming.
  • A need exists for simpler, more reliable techniques to delineate these planes.

Purpose of the Study:

  • To introduce and evaluate a novel technique for intersegmental plane identification in lung segmentectomy.
  • To demonstrate the efficacy of indocyanine green (ICG) for visualizing lung parenchyma planes.
  • To provide a straightforward method applicable to atypical segmentectomies.

Main Methods:

  • A new technique using indocyanine green (ICG) medium was developed.
  • The method involves ligation of the segmental vein to retain ICG.

  • ICG is subsequently injected through the segmental bronchus.

    • Main Results:

    • The ICG technique allows for easy identification of intersegmental planes.
    • Visualization is achieved through a distinct color change on the lung surface and within the parenchyma.
    • This method simplifies the delineation of surgical margins.

    Conclusions:

    • The described indocyanine green technique offers a simple and effective solution for identifying intersegmental planes during lung segmentectomy.
    • This approach is particularly beneficial for atypical segmentectomies, enhancing surgical precision.
    • The technique facilitates clear visualization of the surgical target, potentially improving patient outcomes.
