Indocyanine green fluorescent imaging in laparoscopic hepatectomy

The literatures on indocyanine green fluorescent imaging in hepatectomy, especially in laparoscopic hepatectomy were reviewed by retriving Web of science, Pubmed, China National Knowledge Infrastructure (CNKI) and Wanfang database. To view the progress and limitations of indocyanine green fluorescent imaging in laparoscopic hepatectomy. Indocyanine green fluorescent imaging can: ⑴ effectively detect and differentiate tumor; ⑵ visualize the staining of liver segment and differentiate bile duct ; ⑶ detect bile leakage. However, high false positive rate and limitation in depth in tumor detectation are still the major disadvantages of indocyanine green fluorescent imaging. Also, the best dose and interval of indocyanine green are unknown. Indocyanine green fluorescent imaging will be very usefull in laparoscopic hepatectomy in future, also need to be explored in details, especially in oncology effect.
