    Area of Science:

    • Surgical Innovation
    • Medical Imaging
    • Oncology

    Background:

    • Segmentectomy with indocyanine green (ICG) is crucial for early-stage lung cancer treatment, aiming for complete resection and lung function preservation.
    • Identifying the intersegmental plane during surgery is challenging due to a lack of effective intraoperative imaging, potentially impacting patient prognosis.

    Purpose of the Study:

    • To develop and evaluate a novel wireless wearable fluorescence image-guided surgery system (LIGHTEN) for accurate intersegmental plane identification.
    • To enhance surgical precision and outcomes in pulmonary segmentectomy procedures.

    Main Methods:

    • Development of the LIGHTEN system, incorporating a handle, light source, Google Glass for augmented reality display, and laptop with application software.
    • In vivo testing of the LIGHTEN system through twelve pulmonary segmentectomy procedures in swine, using intravenous indocyanine green (ICG) injection.

    Main Results:

    • The LIGHTEN system successfully displayed clear, real-time, black-and-white transition zones, enabling effortless and rapid identification of intersegmental planes in all swine.
    • Surgeons reported that the system facilitated quick and easy discernment of surgical planes.

    Conclusions:

    • The wireless wearable fluorescence image-guided surgery system (LIGHTEN) effectively enables precise identification of intersegmental planes during pulmonary segmentectomy.
    • LIGHTEN offers mobility and high sensitivity, demonstrating significant potential to improve surgical accuracy and patient outcomes in lung cancer treatment.
