Clinical application of projection mapping technology for surgical resection of lung metastasis

Abstract

Indocyanine green fluorescent image-guided surgery was developed to identify primary and metastatic nodules of various malignancies. However, currently, surgeons need to identify the fluorescent image on a monitor, which impedes surgical procedures. Herein, we developed a novel projection mapping device that can cast the real-time fluorescent image onto the surface of the targeted organ. We performed surgical resection of a lung metastasis of hepatoblastoma using this technique. The projection mapping technique clearly detected the pulmonary lesion, and no other lesions were identified in the ipsilateral thorax. The patient is well and free of recurrence 2 years after surgery.
