Background: Posthepatectomy liver failure (PHLF) may occur after ALPPS (Associating liver partition and portal vein ligation for staged hepatectomy) despite a sufficient standardized future liver remnant (sFLR) volume. The aim of this study was to test kinetic growth rate (KGR) after ALPPS stage 1, describing the percentage increase of sFLR per day, as a predictor of PHLF after completion of ALPPS.
Methods: The ability of KGR to predict PHLF after ALPPS stage 2 was investigated in 38 patients. PHLF was defined according to the "50-50" and ISGLS criteria.
Results: Completion of ALPPS was achieved in 95% (36/38) of patients. The incidence of PHLF was 22% (8/36) and 36% (13/36) according to "50-50" and ISGLS criteria, respectively. Whereas a sFLR cut off at 30% alone failed to predict PHLF, KGR ≥6%/day after stage 1 was associated with a significant reduced risk of PHLF ("50-50", p = 0.03/ISGLS, p = 0.03) after stage 2. Adherence to both concomitant KGR ≥6%/day and sFLR ≥30% reduced the incidence of PHLF to 0%.
Conclusions: Assessment of KGR is a novel tool to estimate the risk of PHLF after ALPPS. Respecting KGR and sFLR after ALPPS stage 1 may increase safety in patients undergoing ALPPS.

Risk factors for wound complications after associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) compared to repeated liver resection - a propensity score matching analysis.

Aim: Sufficient liver function is crucial in extracellular matrix growth, hemostasis, and wound healing. Repeated abdominal surgery is a known risk factor for the development of wound complications. This study aimed to evaluate this high-risk constellation in patients undergoing associated liver partition and portal vein ligation for staged hepatectomy (ALPPS) and repeated liver resections (RLR) in comparison to single liver resection (SLR).

Article Synopsis
- Post-hepatectomy liver failure (PHLF) poses a major risk for patients after partial liver surgery, with a need for better prognostic markers and treatments to boost liver recovery.
- A study analyzed plasma samples from nine hepatocellular carcinoma (HCC) patients before and after surgery to identify proteins in extracellular vesicles (EVs) that might indicate liver regeneration status.
- The findings revealed significant changes in protein levels in patients with PHLF, highlighting disruptions in critical cellular processes and suggesting potential biomarkers that were present before the surgery.

Objective The influence of macrovascular invasion on the therapeutic efficacy of Associating Liver Partition and Portal Vein Ligation for Staged Hepatectomy (ALPPS) in hepatocellular carcinoma (HCC) patients has not been previously reported. This study primarily examines the therapeutic effect of ALPPS in treating HCC with macrovascular invasion. Methods 89 patients who underwent ALPPS at the First Affiliated Hospital of Guangxi Medical University from December 2016 to December 2021 were included.

Objective: The objective of this study was to evaluate the long-term oncological outcomes of patients with colorectal liver metastasis (CRLM) randomized for associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) or 2-stage hepatectomy (TSH).
Introduction: For advanced CRLM, TSH or ALPPS may be needed for tumor freedom. The randomized, controlled, multicenter trial LIGRO showed an increased resection rate in patients who underwent ALPPS but no difference in morbidity or mortality.

Background: The regenerative capacities of the liver and improvements in surgical techniques have expanded the possibilities of resectability. Liver resection is often the only curative treatment for primary and secondary malignancies, despite the risk of post-hepatectomy liver failure (PHLF). This serious complication (with a 50% mortality rate) can be avoided by better assessment of liver volume and function of the future liver remnant (FLR).
