Determination of the surgical margin in laparoscopic liver resections using infrared indocyanine green fluorescence

Laparoscopic liver resection is increasingly used to treat patients with hepatic tumor. However, during laparoscopic resection, information obtained by palpation using laparoscopic forceps or from intraoperative ultrasonography is extremely limited, which may pose a risk for positive surgical margins. This study aimed to investigate the feasibility and clinical application of near-infrared (NIR) fluorescence imaging to guide laparoscopic liver...
