Liver Transplant Fast-Track With an Emphasis on Reduced Delirium: A Multidisciplinary Approach to Reducing Length of Stay.

Enhanced recovery after surgery protocols have been shown to reduce length of stay in transplant patients. The purpose of our study was to evaluate the impact of a standardized protocol in liver transplant recipients (LTR) on length of stay (LOS) and delirium during the index hospitalization post-LT. Elements of the protocol included reduced intraoperative corticosteroids (from methylprednisolone 1000 to 250 mg), conversion of steroid taper to be administered once-daily instead of BID, optimal end-of-case intraoperative extubation, multimodal analgesia, early removal of surgical drains, implementation of dietary and physical therapy plans and education for multidisciplinary providers and patients about expected LOS.

Validation of a Pretransplant Risk Prediction Model for Early Allograft Dysfunction After Living-donor Liver Transplantation.

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.

Complete transition from laparoscopic to robotic liver surgery achieves superior outcomes in difficult hepatectomies: a seven-year retrospective study.

Background: Minimally invasive liver surgery (MILS) is superior to open surgery when considering decreased blood loss, fewer complications, shorter hospital stay, and similar or improved oncologic outcomes. However, operative limitations in laparoscopic hepatectomy have curved its applicability and momentum of complex minimally invasive liver surgery. Transitioning to robotic hepatectomy may bridge this complexity gap.

Durvalumab-Induced Immune Thrombocytopenia in Patients with Advanced Cholangiocarcinoma Undergoing Yttrium-90 Radioembolization.

Introduction: Immune thrombocytopenia (ITP) secondary to durvalumab, a programmed cell death ligand 1 inhibitor, is a rare but clinically significant immune-related adverse event. Herein, we present 2 patients with cholangiocarcinoma who developed ITP immediately post-yttrium-90 radioembolization (Y90-RE) while on durvalumab-based systemic therapy. We hypothesize that given the timing, the immunotherapy and the radioembolization combination led to this event.

Spectrum of Findings Seen in Patients With Cholangiocarcinoma.

BackgroundCholangiocarcinoma-with a growing incidence rate and poor prognosis-is not an uncommon cancer. Molecular profiling can reveal actionable aberrations in at least a third of the tumors. This is especially so in the case of intrahepatic cholangiocarcinoma (ICC), where mutations in the isocitrate dehydrogenase 1 and 2 genes () make up 15%-20% of these tumors.

Minimally invasive tools are necessary for the modern practice of liver surgery.

Introduction: Minimally invasive liver resection (MILR) is performed for other gastrointestinal applications. At our centre, all liver resections are systematically performed using a minimally invasive approach. This study aimed to describe our experience in minimising open surgery and emphasised the importance of minimally invasive surgery.

Biliary complications after adult-to-adult living-donor liver transplantation: An international multicenter study of 3633 cases.

In living-donor liver transplantation, biliary complications including bile leaks and biliary anastomotic strictures remain significant challenges, with incidences varying across different centers. This multicentric retrospective study (2016-2020) included 3633 adult patients from 18 centers and aimed to identify risk factors for these biliary complications and their impact on patient survival. Incidences of bile leaks and biliary strictures were 11.

Neoadjuvant botensilimab plus balstilimab response pattern in locally advanced mismatch repair proficient colorectal cancer.

In patients with locally advanced cancer without distant metastases, the neoadjuvant setting presents a platform to evaluate new drugs. For mismatch repair proficient/microsatellite stable (pMMR/MSS) colon and rectal cancer, immunotherapy has shown limited efficacy. Herein, we report exceptional responses observed with neoadjuvant botensilimab (BOT), an Fc-enhanced next-generation anti-CTLA-4 antibody, alongside balstilimab (BAL; an anti-PD-1 antibody) in two patients with pMMR/MSS colon and rectal cancer.

Living Donor Liver Transplantation for Hepatocellular Carcinoma Within and Outside Traditional Selection Criteria: A Multicentric North American Experience.

Objective: To evaluate long-term oncologic outcomes of patients post-living donor liver transplantation (LDLT) within and outside standard transplantation selection criteria and the added value of the incorporation of the New York-California (NYCA) score.

Background: LDLT offers an opportunity to decrease the liver transplantation waitlist, reduce waitlist mortality, and expand selection criteria for patients with hepatocellular carcinoma (HCC).

Methods: Primary adult LDLT recipients between October 1999 and August 2019 were identified from a multicenter cohort of 12 North American centers.

Novel Benchmark for Adult-to-Adult Living-donor Liver Transplantation: Integrating Eastern and Western Experiences.

Objective: To define benchmark values for adult-to-adult living-donor liver transplantation (LDLT).

Background: LDLT utilizes living-donor hemiliver grafts to expand the donor pool and reduce waitlist mortality. Although references have been established for donor hepatectomy, no such information exists for recipients to enable conclusive quality and comparative assessments.

National survey of second opinions for hospitalized patients in need of liver transplantation.

Decisions about patient candidacy for liver transplant (LT) can mean the difference between life and death. We surveyed LT centers across the United States to assess their perceptions of and barriers to second-opinion referrals for inpatients declined for transplant. The medical and surgical directors of 100 unique US LT programs that had done >20 LTs in 2021 were surveyed with a 33-item questionnaire including both multiple-choice and free-response questions.

Advances and innovations in living donor liver transplant techniques, matching and surgical training: Meeting report from the living donor liver transplant consensus conference.

The practice of LDLT currently delivers limited impact in western transplant centers. The American Society of Transplantation organized a virtual consensus conference in October 2021 to identify barriers and gaps to LDLT growth, and to provide evidence-based recommendations to foster safe expansion of LDLT in the United States. This article reports the findings and recommendations regarding innovations and advances in approaches to donor-recipient matching challenges, the technical aspects of the donor and recipient operations, and surgical training.

Vibration Controlled Transient Elastography to Evaluate Steatosis in Candidate Living Donors for Liver Transplantation.

Background: The ability of vibration controlled transient elastography (VCTE) to reliably exclude significant steatosis in living donor candidates could obviate the need for invasive liver biopsies, expedite the donor approval process, and reduce recipient wait time. We therefore aimed to determine whether VCTE controlled attenuation parameter (CAP) could be used to detect steatosis in potential living donors.

Methods: Living donor candidates who presented for evaluation between 2016 and 2019 underwent standard donor workup, VCTE, and liver biopsy if indicated.

Safety and Efficacy of Robotic vs Open Liver Resection for Hepatocellular Carcinoma.

Importance: Long-term oncologic outcomes of robotic surgery remain a hotly debated topic in surgical oncology, but sparse data have been published thus far.

Objective: To analyze short- and long-term outcomes of robotic liver resection (RLR) for hepatocellular carcinoma (HCC) from Western high-volume centers to assess the safety, reproducibility, and oncologic efficacy of this technique.

Design, Setting, And Participants: This cohort study evaluated the outcomes of patients receiving RLR vs open liver resection (OLR) for HCC between 2010 and 2020 in 5 high-volume centers.

Practice patterns of the medical evaluation of living liver donors in the United States.

Living donor liver transplantation (LDLT) can help address the growing organ shortage in the United States, yet little is known about the current practice patterns in the medical evaluation of living liver donors. We conducted a 131-question survey of all 53 active LDLT transplant programs in the United States to assess current LDLT practices. The response rate was 100%.

Ex Vivo Liver Resection and Autotransplantation: Should It be Used More Frequently?

Objective: We herein advocate for more extensive utilization of ex vivo resection techniques for otherwise unresectable liver tumors by presenting the largest collective American experience.

Background: Advanced in situ resection and vascular reconstruction techniques have made R0 resection possible for otherwise unresectable liver tumors. Ex vivo liver resection may further expand the limits of resectability but remains underutilized due to concerns about technical complexity and vascular thrombosis.

Black patients and women have reduced access to liver transplantation for alcohol-associated liver disease.

Although sex and racial disparities for liver transplantation (LT) are known, it is unclear if disparities exist for patients with alcohol-associated liver disease (ALD). We aimed to compare sex and racial/ethnic differences in mortality, LT listing, and LT rates in patients with and without ALD. We analyzed patients who were listed for LT and/or died of end-stage liver disease (ESLD) between 2014 and 2018 using the United Network for Organ Sharing Standard Transplant Analysis and Research and Centers for Disease Control and Prevention Wide-ranging OnLine Data for Epidemiologic Research databases, respectively.

Sociodemographic characteristics of living liver donors: Few changes over 20 years.

Introduction: Although there are well-documented challenges in access to living donor liver transplant (LDLT) among recipients, it is unclear whether living liver donors (LLDs) face similar challenges.

Methods: We analyzed the UNOS Standard Transplant Analysis and Research database, including LLDs ≥ 18 years in the United States from 1/1998 to 12/2018. We compared sociodemographic characteristics (age, gender, race/ethnicity, education level, employment status, BMI, and relationship to recipient) of LLDs across three eras-pre-MELD (1998-2002), MELD (2003-2013), and post-direct acting antivirals (DAA) (2014-2018).

Assessing motivations for non-living and living organ donation among individuals with and without a history of blood donation.

Objectives: The current study investigated relationships between a history of blood donation, registration as a non-living and living organ donor, and differential motivations.

Background: Motivational commonalities exist between blood and organ donors, but there is no prior data on the relationships between blood donation history and both living and non-living organ donor registration and motivation.

Methods/materials: Participants completed online surveys assessing blood donation history, organ donor registration and interest, and motivations related to donation behaviour.
