Navigation surgery using ICG-fluorescence method for hepatoblastoma and hepatocellular carcinoma

Abstract

Indocyanine green fluorescence method can be used for detecting primary or metastatic lesions of hepatoblastoma and hepatocellular carcinoma intraoperatively. Using this method for lung metastatic surgery, extremely tiny lesions can be visualized and extirpated easily. For primary liver surgery, tiny residual tumors on cut surface of the liver can be visualized and extirpated. Users should be reminded that false positive rate is relatively high. Whether this method can improve the prognosis of these diseases is still unclear, but it can certainly reduce the operation time because of avoiding intraoperative histopathological confirmation. This navigation can permit partial resection of the lung or the liver safely instead of lobectomy or segmentectomy, confirming no residual tiny tumors on cut surface.
