Background and Aims: Liver transplant is a specialized treatment for a spectrum of indications that use a scarce resource. Transplant is guided by principles of justice, equity, and benefit, with a constant conflict between competing interests. Organs are a national resource with a goal of equitable distribution across sites. An AASLD guideline for the evaluation and selection of appropriate candidates for transplant has been available since 2005. Methods: A multidisciplinary writing group of liver transplant experts and a librarian convened over 24 months. The writing group reviewed the literature, generated guideline recommendations, and rated the level of evidence for each recommendation based on the Oxford Center for Evidence-Based Medicine. The group categorized the strength of recommendations based on the level of evidence, risk-benefit ratio, and patient preferences. Conclusions: Liver transplant is a lifesaving procedure that should be offered to selected patients with clear indications and a reasonable prospect of benefit. The evaluation is designed to identify those in need, to outline hurdles to a successful outcome, and to develop an effective transplant plan. The goal of this document is to provide a template for this process.

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.

Background. Liver transplantation (LT) is the standard treatment for liver failure secondary to alcohol-associated liver disease, but limited literature and best practices exist for post-LT treatment of alcohol use disorder (AUD). This study explores current AUD management practices and providers’ perceived barriers to effective post-LT AUD management. Methods. A 45-item survey on post-LT AUD treatment practices was distributed to members of the American Society of Transplant Surgeons, the Association of Consult/Liaison Psychiatry Transplant Special Interest Group, and both the American Society of Transplantation’s Liver and Intestine Community of Practice and Psychosocial and Ethics Community of Practice discussion boards, between December 2021 and April 2022. Univariate analysis of categorical variables was performed using the chi-square test. Data were analyzed using center volume tertiles, country region, and provider professional activity. Results. Two hundred thirty-two respondents from 70 LT centers across all 11 United Network for Organ Sharing regions completed the survey. Half of the them were attending physicians and 16.4% were nurse coordinators. Most centers (84%) aimed for alcohol abstinence for all post-LT patients. Perceived barriers to AUD treatment efficacy included ongoing desire to drink (18%), denial about alcohol misuse (14.9%), and lack of posttransplant support (14%). Additionally, 62.1% of centers had no policy for prescribing medication-assisted therapy to treat AUD, and 32.7% of centers reported no center-level changes in AUD care. Providers identified primary needs as hiring additional mental health professionals (30.8%), dedicating specific staff to AUD care (24.7%), and standardizing psychiatric/psychological care in transplant clinics (17.2%). Conclusions. Despite the increasing volume of LT for alcohol-associated liver disease, significant perceived barriers to effective AUD treatment remain.

ABSTRACTRobotic‐assisted bronchoscopy (RAB) has improved lung nodule evaluation, but its feasibility to biopsy aortopulmonary lymph nodes remains underexplored. This study explored the safety and effectiveness of RAB for sampling aortopulmonary lymph nodes suspected of malignancy. We conducted a literature review on RAB for aortopulmonary lymph node biopsy and present a case of a patient with a history of malignancy. Using the Ion Endoluminal System, we navigated to the anterior segment of the left upper lobe to access a subaortic lymph node in a patient with a history of mantle cell lymphoma. Biopsy confirmed disease recurrence. Our literature review identified seven patients who underwent RAB to assess aortopulmonary lymph nodes, with most findings showing small‐cell lung cancer. Our study reports an 88% diagnostic yield, and no complications associated with the procedure. RAB is a safe and effective approach for biopsying aortopulmonary lymph nodes.

In a setting characterized by a growing prevalence of patients with alcohol-associated and metabolic dysfunction–associated steatotic liver diseases, coupled with an aging patient demographic, the incidence of cardiac comorbidities in liver transplant candidates is on the rise. These comorbidities not only pose barriers to transplant eligibility but also impact the intraoperative course and affect posttransplant outcomes. As such, there is a significant need to optimize the clinical management of these cardiac comorbidities. However, there is a scarcity of evidence regarding the best practices for managing cardiac comorbidities such as coronary and valvular heart diseases, arrhythmia, and cardiomyopathy in this population, both before and during transplant surgery. These conditions necessitate a coordinated and multidisciplinary approach to care. In this manuscript, we conduct a comprehensive review of the most recent evidence pertaining to the preoperative and intraoperative management of these cardiac comorbidities in liver transplant candidates. Our aim is to provide recommendations that improve and standardize their clinical care.
