Background/aims: Liver transplantation (LT) is promising method of treatment for hepatocellular carcinoma (HCC) patients, but is limited by donor organ shortages and tumor progression during long wait periods. This study investigated the efficacy of salvage living donor LT (LDLT) after initial liver resection (LR) in HCC patients.
Methods: Sixty patients with HCC who underwent primary LDLT (n = 45) or salvage LDLT after initial LR (n = 15) were enrolled. Significant prognostic variables determined by univariate analysis were subjected to multivariate analysis using a Cox proportional hazard regression model. Cox proportional hazards models with inverse probability of treatment weighting (IPTW) based on propensity score were used to adjust for selection bias between groups.
Results: The salvage group had significantly higher Child-Pugh class A (p = 0.003), ≥3 pretransplant treatments (p = 0.007), and reoperation rates for postoperative bleeding (p = 0.032) than the primary LDLT group, whereas overall and recurrence-free survival rates were comparable. After IPTW matching, the salvage LDLT group had significantly more reoperations for postoperative bleeding (hazard ratio 7.948, p = 0.017).
Conclusions: First-line LR followed by salvage LDLT allows survival equal to that of primary LDLT. Salvage LDLT following primary LR could be an effective therapy.

Insufficient pretransplant induction therapy is associated with diffuse intrahepatic cholangiopathy in ABO-incompatible living donor liver transplantation for acute liver failure.

Background: ABO-incompatible liver transplantation (ABOi LT) can now be successfully performed with standard pretransplant induction therapy. For patients with chronic end-stage liver disease (ESLD), ABOi LT can achieve long-term outcomes comparable to those of blood type-compatible (ABOc) LT. Outcomes of patients with acute liver failure (ALF) who undergo urgent transplantation surgery with a limited induction period should be further investigated.

Background: Hepatocellular carcinoma (HCC) is a leading cause of cancer-related mortality. While liver transplantation (LT) provides the best long-term survival, it is constrained by organ scarcity and strict criteria. Liver resection (LR) is often the initial treatment for patients with solitary tumors and preserved liver function.

We evaluated the liver transplantation (LT) criteria in acute-on-chronic liver failure (ACLF), incorporating an urgent living-donor LT (LDLT) program. Critically ill patients with a Chronic Liver Failure Consortium (CLIF-C) ACLF score (CLIF-C_ACLF_score) ≥65, previously considered unsuitable for LT, were included to explore the excess mortality threshold of the CLIF-C_ACLF_score (CLIF-C_ACLF_score_threshold). We followed 854 consecutive patients with ACLF (276 ACLF grade 2 and 215 ACLF grade 3) over 10 years among 4432 LT recipients between 2008 and 2019.

Background: Transfusion of allogeneic blood products can have adverse effects and profoundly influence postoperative liver transplantation outcomes, including graft survival. To minimize allogeneic red blood cell (RBC) transfusion, salvaged blood can be used during liver transplantation. The aim of this study was to determine the contribution of salvaged blood to allogeneic RBC transfusion in living donor liver transplantation (LDLT) recipients.

Background: IPVS is considered a last resort or a salvage procedure in the event of recurrent PV thrombosis despite multiple attempts at redo PV anastomosis. We employed the opened umbilical vein approach to place the stent in the PV and deliver anticoagulation through a catheter.
Materials And Methods: From Jan 2017 to Feb 2022, 150 patients underwent pediatric transplantation at department of liver transplant and hepatobiliary surgery unit, Indraprastha Apollo hospitals, New Delhi.
