Special Issue Information

Dear Colleagues,

We would like to invite you to contribute to this Special Issue, “Current Challenges and New Perspectives in Liver Transplantation”. Liver transplantation (LT) has evolved significantly over the past few decades, becoming a life-saving treatment for various acute and chronic liver diseases. Despite major advances in surgical techniques, immunosuppression, and patient selection, LT still faces several persistent challenges, including donor organ shortage, complications from long-term immunosuppression, the recurrence of primary liver diseases, and disparities in access to transplantation. Additionally, emerging issues, such as transplantation in the context of metabolic dysfunction-associated liver disease (MASLD), hepatocellular carcinoma beyond traditional criteria, and transplantation for acute-on-chronic liver failure, are reshaping the landscape and require updated, evidence-based approaches. With the advent of precision medicine, machine learning, and minimally invasive diagnostics, new perspectives present opportunities to improve outcomes and individualized care.

This Special Issue aims to provide a comprehensive overview of the current state and future directions in liver transplantation. It seeks high-quality contributions that align with the journal’s scope by advancing our understanding of clinical research in hepatology and transplantation medicine. Our goal is to compile a diverse range of studies that reflect innovative thinking, multidisciplinary collaboration, and the latest developments in this dynamic field.

Topics of interest include (but are not limited to) the following:

Expanding indications for liver transplantation;
Biomarkers and imaging in transplant evaluation and follow-up;
Post-transplant complications and immunosuppression strategies;
Outcomes in special populations (elderly, pediatric, and HIV-positive recipients);
Health equity and access to transplantation;
Artificial liver support systems and bridge-to-transplant strategies;
Recurrent and de novo malignancies post transplant;
The role of artificial intelligence and precision medicine in transplant decision making.

Original research articles and comprehensive review papers are welcome.

We look forward to receiving your contributions and hope to advance this field of research and foster new collaborations.

Abstract

Background/Objectives: Biliary reconstruction in liver transplantation (LT) for primary sclerosing cholangitis (PSC) is controversial. A Roux-en-Y hepaticojejunostomy (HJ) is associated with fewer anastomotic strictures, while a duct-to-duct reconstruction (DD) shows a decreased rate of cholangitis and preserves anatomy for endoscopy. The aim of our study was to analyze patient survival and postoperative outcomes after LT for PSC based on the type of reconstruction in two high-volume LT centers. Methods: We included 94 PSC patients who underwent a primary LT between 2010 and 2024. The association of biliary reconstruction with patient survival was assessed with the Kaplan–Meier method. Predictors of mortality and postoperative complications were identified via Cox and logistic regression. Results: In total, 42 patients received an HJ and 52 patients received a DD. There was no difference in patient survival or major complications. DD resulted in an increased number of anastomotic strictures, whereas anastomotic insufficiency, ischemia, cholangitis, and the need for revision surgery showed no difference. The choice of biliary reconstruction technique was not a predictor for mortality or major complications. Conclusions: Both types of biliary reconstruction are effective for PSC patients, with comparable patient survival and postoperative outcomes. Although DD is associated with an increased number of strictures, endoscopic treatment options provide a feasible solution. Full article

Abstract

Background: Metabolic dysfunction-Associated Steatotic Liver Disease (MASLD) is becoming a leading indication for liver transplantation in the United States. In this growing recipient population, the combined effects of underlying liver disease etiology and associated comorbidities on the evaluation pathway to transplantation warrant closer examination of patient outcomes. Methods: We analyzed adult liver transplant referrals (n = 9981) from the California Liver Network, a multi-center retrospective cohort spanning six high-volume California transplant centers between 2018 and 2020. A total of 6709 patients who underwent formal evaluation were included. Patients were stratified by MASLD vs. non-MASLD etiology and compared for demographics, comorbidities, transplant evaluation timelines, listing rates, and outcomes. Results: MASLD patients (n = 1477) were older, had higher BMI, and had greater prevalence of metabolic comorbidities than non-MASLD patients (n = 5232; p < 0.001 for all). Compared to non-MASLD candidates, MASLD patients were more likely to be waitlisted (OR 1.52, 95% CI 1.33–1.74; p < 0.001). However, MASLD and non-MASLD patients had no statistically significant difference in the rate of transplant (p = 0.182), with clinically similar but statistically inferior post-transplant survival outcomes at 5 years post-transplant (88% vs. 83%; p = 0.014). Competing-risk analysis showed that MASLD candidates had higher cumulative incidence of death on the waitlist (p < 0.001), although MASLD was not independently associated with waitlist mortality when adjusting for covariates (p = 0.300). MASLD patients demonstrated increased mortality following waitlist removal (HR 1.64, 95% CI 1.14–2.35; p = 0.008), primarily among those removed for clinical deterioration (HR 1.50, 95% CI 1.01–2.23; p = 0.044). Conclusions: MASLD patients face unique challenges in liver transplant evaluation. MASLD patients are associated with higher comorbidities, increased incidence of waitlist mortality, and significantly higher mortality rate following waitlist removal. However, transplantation provides significant survival benefit with comparable outcomes to non-MASLD recipients; thus, early access to transplant may optimize outcomes for MASLD liver transplant candidates.

Abstract

Background: Coronary artery disease (CAD) is common among liver transplantation (LT) candidates, yet whether pre-transplant percutaneous coronary intervention (PCI) improves post-LT outcomes remains uncertain. Methods: We conducted a single-center, Institutional Review Board-approved cohort study of adults undergoing LT from 2005 to 2025. Asymptomatic candidates with significant stenosis on invasive angiography were included; prior coronary artery bypass grafting was excluded. The primary endpoint was major adverse cardiovascular events (MACE: myocardial infarction [MI], stroke/transient ischemic attack, new systolic dysfunction, post-LT coronary revascularization, or all-cause death). Results: Among 111 patients (median age 65 years; 84% male), 66 (59%) underwent PCI and 45 (41%) were managed medically. Over a median 32 months of follow-up, 61 patients (55%) experienced MACE. Composite MACE did not differ between PCI and non-PCI groups (52% vs. 60%, p = 0.40; log-rank p = 0.59). Fine–Gray modeling showed no association of PCI with MACE; independent predictors were prior MI (HR 1.81, 95% CI 1.01–3.24) and pre-transplant dialysis (HR 2.13, 95% CI 1.07–4.24). Major bleeding occurred in 7%. Matched and era-stratified analyses were concordant. Conclusions: In asymptomatic LT candidates with angiographically severe CAD, pre-LT PCI was not associated with a lower incidence of post-LT MACE. Full article
