Application of indocyanine green fluorescence imaging in laparoscopic hepatectomy

Minimally invasiveness and accuracy are the aim of modern hepatobiliary surgery. Under the guidance of this concept, laparoscopic hepatectomy turns to be more mature and standardized. However, there are still some limitations for laparoscopy. Indocyanine green fluorescence imaging technique can accurately locate tumors, mapping liver segments, and display biliary tract. It is an effective real-time tool to guide the parenchymal transection accurately during operation. It can also detect small lesions and bile leakage. Indocyanine green fluorescence imaging technique makes up the limitations of laparoscopic surgery, providing better conditions for accurate surgery. In this paper, we summarized the application of indocyanine green fluorescence imaging technique in laparoscopic hepatectomy.
