Background: Despite continuous progress in the field of liver transplantation, considerable proportion of patients still suffer from the postoperative graft dysfunction. Clinically, it presents as early allograft dysfunction (EAD), and its more severe form defined as primary nonfunction (PNF). Posttransplant liver dysfunction translates into significantly worse treatment outcomes. Summary: Both entities are multifactorial, with donor (graft), recipient, and procedure-related factors playing the key roles. Ischemia-reperfusion injury is a major driver of their development. So far, various noninvasive (pharmacological) and invasive strategies have been tested to mitigate its negative effects. This article pre­sents the current approach to diagnosis, prediction, and management of EAD and PNF. Key Messages: Different pharmacological interventions may be considered to improve graft function after liver transplantation. Machine perfusion seems to be the most effective method at the moment.

Hepatocellular carcinoma (HCC) is one of the most frequent indications for liver transplantation. However, the transplantation is ultimately associated with the occurrence of ischemia-reperfusion injury (IRI). It affects not only the function of the graft but also significantly worsens the oncological results. Various methods have been used so far to manage IRI. These include the non-invasive approach (pharmacotherapy) and more advanced options encompassing various types of liver conditioning and machine perfusion. Strategies aimed at shortening ischemic times and better organ allocation pathways are still under development as well. This article presents the mechanisms responsible for IRI, its impact on treatment outcomes, and strategies to mitigate it. An extensive review of the relevant literature using MEDLINE (PubMed) and Scopus databases until September 2020 was conducted. Only full-text articles written in English were included. The following search terms were used: “ischemia reperfusion injury”, “liver transplantation”, “hepatocellular carcinoma”, “preconditioning”, “machine perfusion”.

Background Although transplant benefit appears superior for patients with advanced hepatocellular cancer (HCC), liver transplantation remains limited to selected low-risk HCC patients to keep their...

Background: The need for safe and efficient dissemination of minimally invasive approach in liver surgery is among the current challenges for hepatobiliary surgeons. After the stage of innovators and pioneers, the following countries should adopt a laparoscopic approach. The aim of this study was to assess the national experience and trend in implementing laparoscopic liver resection (LLR) in Poland. Materials and methods: A national registry of LLR performed in Poland was established in June 2020. All LLR cases performed before were included retrospectively, followed by prospectively collected new cases. Baseline characteristics, preoperative and intraoperative data, short-term results and long-term follow-up were recorded. Results: Since 2010 up to the end of 2022 there were 718 LLRs performed in Poland. The national rate of laparoscopic approach has gradually increased since 2017 (P<0.001), reaching the rate of 11.7% in 2022. There were 443 (61.7%), 107 (14.9%), and 168 (23.4%) LLRs performed in accordance to increasing grades of difficulty. The move towards more demanding cases had an increasing trend over the years (P<0.001). Total intraoperative adverse event and postoperative severe complications rates were estimated for 13.5% (n=97) and 6.7% (n=48), respectively. 30-day reoperation, readmission and postoperative mortality rates were 3.6% (n=26), 2.8% (n=20), and 0.8% (n=6), respectively. While the R0 resection margin was assessed in 643 (89.6%) cases, the total textbook outcomes (TO) were achieved in 525 (74.5%) cases. Overcoming the learning curve of 60 LLRs, resulted in an increasing TO rate from 72.3 to 80.6% (P=0.024). Conclusions: It is the first national analysis of a laparoscopic approach in liver surgery in Poland. An increasing trend of minimizing invasiveness in liver resection has been observed. Responsible selection of cases in accordance with difficulty may provide results within global benchmark values and textbook outcomes already during the learning curve.

BACKGROUND:The impact of packed red blood cells (PRBCs) and fresh frozen plasma (FFP) transfusions in patients with hepatocellular cancer (HCC) undergoing liver transplantation has rarely been evaluated. The aim of the current study was to assess the impact of intraoperative transfusions on posttransplant outcomes. MATERIAL AND METHODS:This retrospective cohort study was based on 229 HCC transplant recipients. The primary outcome measure was 5-year recurrence-free survival. Secondary outcome measures comprised overall and long-term survival at 5 years and 90-day mortality. Cox proportional hazard models and logistic regression were used to assess risk factors. RESULTS:After adjustment for potential confounders, no association was found with respect to tumor recurrence for PRBCs (P=0.368) or FFP (P=0.081) transfusions. Similarly, PRBC transfusion (P=0.623) and FFP transfusion (P=0.460) had no impact on survival between 90 days and 5 years. PRBC transfusion increased the risk of 90-day mortality (P=0.005), while FFP transfusion was associated with a lower risk (P=0.036). CONCLUSIONS:Intraoperative transfusions of blood products does not impair recurrence-free and long-term survival of patients with HCC undergoing liver transplantation. Intraoperative PRBC transfusion increases the risk of early mortality, whereas adequate supplementation of FFP plays a protective role.
