Optimal Liver Remnant Volume for Safer Hepatobiliary Resection

In right hepatic trisectionectomy with bile duct resection, this study explored the impact of Future Liver Remnant volume-to-body weight ratio (FLR/BW) and indocyanine green plasma clearance rate (ICGK-F) on posthepatectomy liver failure. Among 91 patients, a FLR/BW ≥ 0.65% significantly reduced the risk of liver failure, while ICGK-F < 0.05 did not. Age, blood loss, and FLR/BW < 0.65% were independent predictors. Establishing FLR/BW ≥ 0.65% as a volumetric criterion may enhance safety in extended hepatobiliary resection.
