Liver remnant volume to body weight ratio of 0.65% as a lower limit in right hepatic trisectionectomy with bile duct resection

Previous studies have suggested the utility of an indocyanine green plasma clearance rate of the future liver remnant (FLR) [ICGK-F] ≥0.05 in hepatobiliary resection to reduce the surgical risk. The present study aimed to verify whether FLR size rather than ICGK-F matters in extended hepatobiliary r...

Description
Summary:Previous studies have suggested the utility of an indocyanine green plasma clearance rate of the future liver remnant (FLR) [ICGK-F] ≥0.05 in hepatobiliary resection to reduce the surgical risk. The present study aimed to verify whether FLR size rather than ICGK-F matters in extended hepatobiliary resection. Between 2004 and 2021, patients who underwent right hepatic trisectionectomy with bile duct resection were included. The impact of the FLR volume-to-body weight ratio (FLR/BW) and ICGK-F on posthepatectomy liver failure (PHLF) was evaluated along with other parameters. Among 91 study patients, the median ICGK-F, FLR and FLR/BW were 0.057 (range, 0.027-0.099), 392 mL (145-705) and 0.78% (0.40-1.37), respectively. PHLF occurred in 23 patients. The incidence was 10 (40%) in 25 patients with an ICGK-F
