Advances in indocyanine green fluorescence imaging during hepatectomy

Abstract

While surgical operation is the preferred treatment for liver malignancies,the postoperative recurrence rate remains high. In the early 21st century,Japanese scientists first reported the use of indocyanine green(ICG) in liver resection. Follow-up studies also found its potential applications such as identifying tumors,determining surgical margins,delineating segmental boundaries,and preventing bile leakage. At present,ICG fluorescence imaging is applied to some types of hepatectomy with excellent effect and is expected to assist in generating surgical strategies for liver malignancies. However,its safety and efficacy still need further studies to evaluate.
