Achieving laparoscopic anatomic resection for hepatocellular carcinoma by fluorescence guided positive staining of hepatic cone unit

<正>Laparoscopic anatomical liver resection has been increasingly reported worldwide, but how to demarcate the resection planes is technically challenging [1]. Positive staining technique with intraoperative indocyanine green(ICG)-fluorescence imaging has been introduced as an effective tool for real-time intraoperative guidance [2].
