Post-hepatectomy liver failure prevention and management
Post-hepatectomy liver failure (PHLF) should be monitored and graded using the International Study Group of Liver Surgery (ISGLS) definition and severity grading system. [1]
PHLF is defined by an increase in international normalized ratio (INR) and concomitant hyperbilirubinemia on or after postoperative day (POD) 5. [1]
Postoperative monitoring strategy
Daily monitoring after hepatectomy should include coagulation and cholestasis markers to detect PHLF progression early. [1]
INR and bilirubin should be trended through POD 5 to capture the ISGLS time window associated with clinically meaningful PHLF. [1]
Severity should be reassessed with ISGLS grade to guide escalation from standard ward management to invasive therapies. [1]
Supportive care principles to reduce liver decompensation
Hemodynamic optimization should be prioritized because reduced hepatic perfusion worsens liver synthetic function failure in the early postoperative period. [2]
Avoidance of additional hepatic insults should be prioritized through careful medication review and supportive organ management. [2]
Nutrition and infection surveillance should be integrated because postoperative infections and systemic inflammation commonly exacerbate liver dysfunction trajectories. [2]
Therapeutic interventions for PHLF by ISGLS grade
ISGLS grade A PHLF generally does not require change in clinical management strategy. [1]
ISGLS grade B PHLF should prompt management escalation including intensified supportive care, typically within a higher-acuity setting. [1]
ISGLS grade C PHLF should prompt urgent consideration of invasive rescue strategies because high-severity grades are associated with major mortality risk. [1]
In ISGLS grade C, escalation options include plasma exchange, artificial liver support, surgical interventions, and evaluation for liver transplantation. [3]
Prevention and management of post-hepatectomy hemorrhage
Post-hepatectomy hemorrhage should be defined and graded using ISGLS criteria to standardize escalation decisions. [4]
Active bleeding should be managed with rapid correction of hemostatic deficits and procedural control when indicated by severity grading and clinical stability. [4]
Severity stratification is clinically relevant because hemorrhage grades correlate with the need for escalating interventions. [4]
Prevention and management of bile leakage
Post-hepatectomy bile leakage should be defined and graded using ISGLS criteria to support targeted drainage and operative or endoscopic decision-making. [5]
Bile leak management should be guided by leakage severity, clinical impact, and feasibility of source control. [5]
Key postoperative decision points to distinguish PHLF from expected recovery
Biochemical kinetics after hepatectomy should be interpreted in relation to ISGLS time points because early lab changes may not represent PHLF, while POD 5 coagulation and hyperbilirubinemia strongly inform grading. [6]
The prospective multicenter validation supported that combining ISGLS severity groups improves mortality prediction compared with the older “50-50 rule” approach. [7]
Common postoperative complications that should be actively ruled out during PHLF workup
Postoperative complications co-occurring with liver dysfunction should be assessed using standardized ISGLS complication frameworks, including hemorrhage and bile leakage, because these directly drive ongoing hepatic injury and systemic decompensation. [4]
PHLF evaluation should prioritize severity grading and targeted management of competing causes that can mimic or worsen liver synthetic failure. [2]
