Introduction: Recently, various types of laparoscopic anatomical liver resection for hepatocellular carcinoma has been actively performed in many centers. Indocyanine green (ICG) fluorescence imaging technique has been increasingly used to visualize biliary anatomy and demarcation of the transected area. This paper reports on laparoscopic anatomical subsegmentectomy for hepatocellular carcinoma using indocyanine green fluorescence imaging technique.
Results: ICG fluorescence was well accumulated in the future liver remnant. It provided clearer demarcation than the conventional demarcation technique. The operation time was 200 minutes, and intraoperative blood loss was negligible. All surgical resection margins were confirmed to be negative for tumor cell. She was discharged on the seventh postoperative day without any complication.
Conclusions: Laparoscopic anatomical subsegmentectomy using indocyanine green fluorescence imaging was a feasible procedure. It could contribute to better identification of subsegment indicated by conventional demarcation technique.
