BACKGROUND: Indocyanine green (ICG) fluorescence guided surgery has been used to treat childhood hepatoblastoma (HB), but the advantages and disadvantages of this technique have not been fully discussed. The purpose of this study is to summarize the experience and to explore the clinical value of this technique for children with HB.
METHODS: 45 children with HB who underwent ICG fluorescence guided surgery (n = 22) and general surgery (n = 23) in our center from January 2020 to December 2022 were enrolled retrospectively.
RESULTS: All the liver tumors in the ICG group showed hyperfluorescence, including total and partial fluorescent types. With the help of ICG navigation, minimally invasive surgery was performed in 3 cases. 18.2 % of cases with tumors could not be accurately identified under white light, but could be identified by fluorescence imaging. The fluorescent cutting lines of 59.1 % of cases were consistent with the safe cutting lines. In 36.4 % of cases, the fluorescence boundary was not clear because of tumor necrosis. In 36.4 % of cases, the fluorescence could not be detected on the inner edge of the tumors because of the depth. A total of 29 ICG (+) suspicious lesions were found during the operations, of which 5 were true positive lesions.
CONCLUSION: ICG fluorescence guided surgery is safe and feasible in children with HB. This technique is helpful for locating tumors, determining margin and finding small lesions with negative imaging, especially in minimally invasive surgery. However, preoperative chemotherapy, tumor necrosis, tumor depth, and ICG administration impact the effect of fluorescence imaging.
