Since 2008, we have applied intraoperative fluorescence imaging using indocyanine green (ICG) to real-time visualization of the bile ducts, hepatic tumors, and hepatic segments during hepatobiliary surgery. With the advent of commercially-available fluorescence imaging system, the ICG-fluorescence imaging techniques have begun to be applied to laparoscopic and robot-assisted surgery widely. Herein, we present a case of laparoscopic hepatectomy for colorectal liver metastases, in which intraoperative ICG-fluorescence imaging was effective for identification of the tumors and evaluation of hepatic perfusion.
