Early allograft failure (EAF) after living donor liver transplantation (LDLT) remains a clinical challenge. Existing prediction models developed for deceased donor transplantation poorly apply to LDLT due to distinct surgical and physiological factors. This study identifies clinical determinants of EAF and develops an LDLT-specific prediction model. We conducted a multicenter retrospective cohort study from 17 high-volume LDLT centers (January 2016–December 2020) with external validation at a tertiary center in Saudi Arabia (January 2015–December 2022). The primary outcome was EAF (graft loss or patient death ≤90 d). Multivariable mixed-effects logistic regression identified preoperative/intraoperative risk factors. The EAGLE-LDLT model was constructed using postoperative laboratory values. Performance was compared against established models (EAD, MEAF, A2ALL) using ROC analysis and decision curve analysis. The development cohort included 2944 adult LDLT recipients (67.7% male; median age 55 y; median MELD 14) with a 5.5% EAF rate. External validation included 1020 recipients (median MELD 21, 6.7% EAF). Independent risk factors for EAF were MELD (OR 1.06, 95% CI 1.04–1.08), donor BMI (OR 1.05, 95% CI 1.00–1.10), portal vein thrombosis (OR 1.73, 95% CI 1.13–2.63), and hepaticojejunostomy (OR 1.58, 95% CI 1.06–2.36). The EAGLE-LDLT model incorporating peak ALT (>468 U/L), peak INR (>1.9), and bilirubin (>3.5 mg/dL) and INR (>1.3) at POD7, demonstrated superior discrimination (AUC=0.81) compared with MEAF (AUC=0.77, p =0.004), EAD (AUC=0.67, p <0.001), and A2ALL (AUC=0.65, p <0.001). EAGLE-LDLT achieved balanced sensitivity (75.0%) and specificity (73.7%), effectively stratifying patients into high-risk (15% of patients; 40.4% EAF incidence) and low-risk groups. Preoperative and intraoperative clinical factors predict EAF in LDLT. The EAGLE-LDLT model accurately identifies LDLT recipients at the highest risk for EAF postoperatively.

Living donor liver transplantation (LDLT) is an established therapy with curative intent for pediatric and adult patients with acute liver failure and end-stage liver disease. Donor safety remains paramount and commences during preoperative evaluation and assessment. Given the importance of the topic, the International Liver Transplantation Society and International Living Donor Liver Transplantation Group consensus conference on Living Liver Donor Safety was convened in March 2025 (Toronto, Canada). Recommendations were based on the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system for assessment of recommendations, and the Danish model of consensus was followed. This report presents 28 recommendations from the working group focused on addressing clinically relevant questions related to the preoperative aspects of living donor safety including assessment of donor acceptability (age, body mass index and hepatic steatosis; medical conditions and contraindications), medical and surgical workup (liver function and procoagulant workup; anatomical considerations and safe remnant), and psychosocial evaluation (timing and team; underlying conditions; non-directed, paired, and anonymous directed donors; urgent living donor workups for acute liver failure).

The success of living donor liver transplantation (LDLT) has bridged the growing gap between organ demand and availability in patients with liver failure or liver cancer. Safety of the living liver donor (LLD) is paramount, and astute intraoperative management plays a critical role in ensuring optimal outcomes for them. Given that intraoperative surgical and anesthesia practices vary widely across centers, the International Liver Transplantation Society (ILTS) and the International Living Donor Liver Transplantation Group (iLDLT Group) convened a global consensus conference in Toronto in March 2025 to develop guidelines for intraoperative management of the LLD. This manuscript details the recommendations on intraoperative considerations for the safety of LLD developed by Working Group II of the Consensus Scientific Committee, using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system for assessment of recommendations, and the Danish model of consensus. Working Group II focused on intraoperative monitoring, fluid and ventilation strategies, surgical techniques for vascular and biliary division, surgeon and center-specific experience, and intraoperative crises planning. These guidelines aim to support both established and emerging LDLT teams to ensure high-quality and safe intraoperative care for the LLD.

Living donor liver transplantation (LDLT) is a life-saving procedure for patients with end-stage liver disease. As its use expands worldwide, ensuring the safety and well-being of live liver donors (LLD) is of paramount importance. Published evidence on early postoperative complications after living donor hepatectomy—those occurring within 90 days of surgery—is limited, and standardized postoperative care protocols are lacking. The International Liver Transplantation Society (ILTS) and the International Living Donor Liver Transplantation Group (iLDLT Group) convened a consensus conference in Toronto in March 2025 to develop guidelines for the safe care of the LLDs. This manuscript details the recommendations on early postoperative considerations for the safety of LLDs developed by Working Group III (WGIII) of the Consensus Scientific Committee, using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system for assessment of recommendations, and the Danish model of consensus. WGIII addressed four key areas: (1) standardized postoperative care, (2) early biliary complications, (3) early postoperative liver dysfunction, and (4) early postdischarge follow-up. This report emphasizes the need for vigilant postoperative monitoring in specialized units, with access to experienced providers and defined clinical pathways. Structured clinical and psychosocial follow-up protocols, perioperative prophylaxis for surgical site infections and venous thromboembolism, and management of early biliary and vascular complications are discussed. These may help standardize care, reduce complications and improve short-term outcomes in LLDs.

Living liver donation is a critical component for addressing organ shortage and improving outcomes for patients with end-stage liver disease. As the prevalence of living donor liver transplantation (LDLT) increases worldwide, understanding and optimizing long-term donor health is paramount. The 2025 International Liver Transplantation Society and International Living Donor Liver Transplantation Society (ILTS-iLDLT) Consensus Conference convened experts in the field of liver transplantation to establish evidence-based guidelines focused on the long-term medical, psychological, and social considerations following living liver donation. The aim of this working group was to integrate current evidence and expert consensus on donor follow-up protocols, risk assessment, and management strategies to promote long-term donor health, quality of life, and living liver donor programs globally to safeguard the welfare of this unique population.

Background. Metabolic dysfunction–associated steatotic liver disease (MASLD) is increasingly recognized as a significant indication for liver transplantation (LT) in North America. Yet data on its impact in other countries, such as Spain, remain limited. This study aimed to evaluate the prevalence and trajectory of MASLD-related LT in Spain and compare these findings with broader national data and international data sets. Methods. Multicenter retrospective cohort study including adults (18 y and older) undergoing LT for MASLD between 2010 and 2023 in 5 large Spanish centers. Additional data were obtained from the Spanish Transplant Registry (Organización Nacional de Trasplantes) and high-prevalence LT centers in the United States (n = 7) and Canada (n = 1). Results. Among 3448 LTs performed in the 5 Spanish centers, 3.4% (n = 117) were MASLD-related. An increasing trajectory of MASLD-related LT was observed, with predictions suggesting a rise to 5.4%–10.8% of LTs for MASLD by 2028. These trends were consistent with Organización Nacional de Trasplantes data. Compared with North American data, the growth trajectory in Spain showed a less steep increase. Hepatocellular carcinoma rates were higher in the Spanish MASLD-LT recipients, yet metabolic comorbidities were frequent in all populations. Conclusions. The burden of MASLD-related LT in Spain is growing, yet at a less pronounced rate than in the United States/Canada. Whether this slower increase will persist or decline in the future as newer antiobesity and MASLD-related drugs are increasingly used is still unknown. In the meantime, our results highlight the need for tailored approaches to management and prevention in the Spanish population and underscore the importance of continued monitoring and research into the evolving impact of MASLD on LT in Spain and beyond.

Variations in liver allocation systems worldwide are presented, with a specific focus on regional differences and their potential impact on outcomes, with the goal of serving as a reference for future policy development. Summaries of liver allocation across multiple European, Scandinavian, and Asian systems, as well as the combined allocation system of Australia plus Canada, the United States, and the systems in Central America, South America, and the Caribbean are reviewed. A comprehensive comparison of how different regions address MELD exceptions, primarily focusing on hepatocellular carcinoma, along with the most common etiologies of liver disease requiring transplantation is presented. In addition, the adoption of living donation and donation after circulatory death is discussed. The study involves contributions from a diverse group of world experts in liver transplantation and may serve as an essential resource to foster international dialogue as countries strive to optimize organ allocation policies, including MELD exceptions.

ABSTRACT Introduction Although liver transplantation (LT) rates have increased globally, the demand for organs still exceeds the supply. This review highlights cultures with significant influences on organ donation and LT. Methods We performed a literature search for articles related to cultures, ethnologies, philosophies, policies, religions, socio‐economic factors, and other influences affecting organ donation in LT around the world. Results There are astonishing similarities between different cultures. In Africa, Asia, and Europe, people often view the postmortem bodies as sacred and believe that their bodies are gifts from “God” or ancestors. To respect the gift of life, to have a chance in reincarnation, or to enjoy life after death, many believe that their bodily sanctity must be preserved. In Asia, Europe, and Latin America, there is a general reluctance to speak about death. Religions also play an important role in people's views on organ donation. Different regions around the world have similar challenges to organ donation, such as misconceptions about organ trafficking, political and economic instability, and a lack of governmental or religious support. Conclusion Addressing the complexities of organ donation and LT requires a multifaceted approach. Culturally sensitive education tailored to diverse communities can dispel myths and misconceptions surrounding organ donation. Fostering partnerships between healthcare providers, religious leaders, community organizations, and policymakers can further facilitate open dialogues and promote organ donation as a noble act to save lives. Social Media Similar cultures around the world post challenges for organ donation. Organizations should foster partnerships between healthcare providers, politicians, and religious leaders to promote donation.

Background. Early allograft dysfunction (EAD) affects outcomes in liver transplantation (LT). Existing risk models developed for deceased-donor LT depend on posttransplant factors and fall short in living-donor LT (LDLT), where pretransplant evaluations are crucial for preventing EAD and justifying the donor’s risks. Methods. This retrospective study analyzed data from 2944 adult patients who underwent LDLT at 17 centers between 2016 and 2020. We developed a logistic regression model to predict EAD based on this development cohort. We used data from 1020 patients at the King Faisal Transplant Center for external validation. Results. In the development cohort, 321 patients (10.9%) experienced EAD. These patients had poorer health status, more liver decompensation, and higher requirements of hospitalization than those without EAD. Multivariable logistic regression identified independent pretransplant predictors of EAD: laboratory Model for End-Stage Liver Disease score (odds ratio [OR], 1.08; 95% confidence interval [CI], 1.06-1.09), the necessity for hospitalization at the time of transplant (OR, 2.58; 95% CI, 2.00-3.30), and graft weight in kilogram (OR, 0.27; 95% CI, 0.17-0.45). Using these predictors, we developed the model for EAD after LDLT, which demonstrated strong discriminative ability in the development cohort with an area under the curve (AUC) of 0.71 (95% CI, 0.68-0.74). The model maintained high discrimination during internal validation (AUC, 0.70; 95% CI, 0.67-0.73) and showed a modest reduction in discriminative power in external validation (AUC, 0.65; 95% CI, 0.61-0.68). Conclusions. EAD post-LDLT is influenced by the recipient’s pretransplant health condition and the graft weight. Integrating the model for EAD after LDLT into the pretransplant process of pairing donors and recipients can enhance the safety and efficacy of LDLT.

Small-for-size syndrome (SFSS) is a well-recognized complication following liver transplantation (LT), with up to 20% developing this following living donor LT (LDLT). Preventing SFSS involves consideration of factors before the surgical procedure, including donor and recipient selection, and factors during the surgical procedure, including adequate outflow reconstruction, graft portal inflow modulation, and management of portosystemic shunts. International Liver Transplantation Society, International Living Donor Liver Transplantation Group, and Liver Transplant Society of India Consensus Conference was convened in January 2023 to develop recommendations for the prediction and management of SFSS in LDLT. The format of the conference was based on the Grading of Recommendations, Assessment, Development, and Evaluation system. International experts in this field were allocated to 4 working groups (diagnosis, prevention, anesthesia, and critical care considerations, and management of established SFSS). The working groups prepared evidence-based recommendations to answer-specific questions considering the currently available literature. The working group members, independent panel, and conference attendees served as jury to edit and confirm the final recommendations presented at the end of the conference by each working group separately. This report presents the final statements and evidence-based recommendations provided by working group 2 that can be implemented to prevent SFSS in LDLT patients.
