Early outcomes of robotic vs open living donor right hepatectomy in a US Center.

Background: Robotic living donor hepatectomy offers potential advantages but has been limited to high-volume centers, primarily in Asia and the Middle East. We report our experience establishing a robotic living donor right hepatectomy program in a U.S.

A Decade of Experience Between Open and Minimally Invasive Hepatectomies for Hepatocellular Carcinoma.

: Hepatic resection offers promising outcomes for patients with hepatocellular carcinoma (HCC) but can be constrained by factors like patient suitability. Continuous advancements in laparoscopic and robotic technologies have made minimally invasive hepatectomies (MIHs) a viable alternative to open hepatectomies with benefits in terms of recovery and complications. : We completed a retrospective review on 138 HCC patients who underwent OH or MIH between 2010 and 2020 at the Hume-Lee Transplant Center.

Utility of scores to predict alcohol use after liver transplant: Take them with a grain of salt.

The Sustained Alcohol use post-Liver Transplant (SALT) and the High-Risk Alcohol Relapse (HRAR) scores were developed to predict a return to alcohol use after a liver transplant (LT) for alcohol-associated liver disease. A retrospective analysis of deceased donor LT from October 2018 to April 2022 was performed. All patients underwent careful pre-LT psychosocial evaluation.

Right versus left fully robotic live donor nephrectomy and open kidney transplantation: Does the laterality of the donor kidney really matter?

Objective: Robotic-assisted live donor nephrectomy (LDN) is being gradually adopted across transplant centers. The left donor kidney is preferred over right due to anatomical factors and ease of procurement. We aimed to study donor and recipient outcomes after robotic procurement and subsequent open implantation of right and left kidneys.

Liver transplantation for post-COVID-19 cholangiopathy: A case series.

Background: Post-COVID-19 cholangiopathy is an emerging cholestatic liver disease observed in patients recovering from severe COVID-19 infection. Its prognosis is poor, necessitating liver transplantation in some cases. This study aimed to investigate the outcomes of liver transplantation for post-COVID-19 cholangiopathy.

Exosomes in transplantation: Role in allograft rejection, diagnostic biomarker, and therapeutic potential.

Exosomes are 50-200 nm-sized extracellular vesicles that are secreted by cells to transfer signals and communicate with other cells. Recent research has revealed that allograft-specific exosomes containing proteins, lipids, and genetic materials are released into circulation post-transplantation which are powerful indicators of graft failure in solid-organ and tissue transplantations. The macromolecular content of exosomes released by the allograft and the immune cells serve as potential biomarkers for assessing the function and the acceptance/rejection status of the transplanted grafts.

Assessment of Culture/Preservation Conditions of Human Islets for Transplantation.

Islet culture before clinical transplantation has been adopted by various centers, but its effect on the survival and function of islets relative to the culture conditions and media needs further assessment. Human islets were cultured or preserved under four different conditions and three media options. Parameters such as recovery, viability, function, islet damage, and gene expressions for markers of hypoxia, and inflammation were assessed after 48-h culture or preservation.

Purification and Isolation of Hepatic Stellate Cells.

Quiescent human hepatic stellate cells (HSCs) serve as important reservoirs of fat-soluble vitamins in the body, namely vitamin A. In an activated form, HSCs are the drivers of fibrosis following chronic liver injury. In non-alcoholic steatohepatitis (NASH) specifically, activated HSCs are drivers of induction and progression of fibrogenesis.

Impact of Portable Normothermic Blood-Based Machine Perfusion on Outcomes of Liver Transplant: The OCS Liver PROTECT Randomized Clinical Trial.

Importance: Ischemic cold storage (ICS) of livers for transplant is associated with serious posttransplant complications and underuse of liver allografts.

Objective: To determine whether portable normothermic machine perfusion preservation of livers obtained from deceased donors using the Organ Care System (OCS) Liver ameliorates early allograft dysfunction (EAD) and ischemic biliary complications (IBCs).

Design, Setting, And Participants: This multicenter randomized clinical trial (International Randomized Trial to Evaluate the Effectiveness of the Portable Organ Care System Liver for Preserving and Assessing Donor Livers for Transplantation) was conducted between November 2016 and October 2019 at 20 US liver transplant programs.

Chyle Leak After Robotic Living Donor Nephrectomy: Literature Review And Management.

Chyle leak after living donor nephrectomy is a rare complication and is associated with a significant postoperative burden. To the best of our knowledge, only 1 case of chyle leak after robotic living donor nephrectomy has been reported in the literature. In this study, we present our experience with 2 cases of chyle leak: 1 after and 1 during robotic donor nephrectomy.

Dissection of External Iliac Artery During Pediatric En bloc Kidney Transplant: Successful Rescue and Reimplant.

En bloc kidney transplant is a surgical treatment option that increases available donor organs and has excellent graft survival for patients with end-stage renal disease. Herein, we report a case of dissection of the external iliac artery that occurred during en bloc kidney transplant in an adult recipient. The en bloc kidneys were removed, flushed, and then reimplanted after restoring the blood flow to the lower limb.

Outcomes of short-duration antiviral prophylaxis for hepatitis C positive donor kidney transplants.

Trials describing 4- to 12-week courses of direct-acting antiviral drugs (DAAs) to treat hepatitis C virus (HCV) transmission from infected donors to uninfected kidney transplant recipients (D+/R- transplants) may be limited in "real-world" application by costs and delayed access to DAAs. We previously reported HCV transmission of 13% among D+/R- transplants with 2- to 4-day pangenotypic sofosbuvir/velpatasvir (SOF/VEL) perioperative prophylaxis, where one patient with HCV transmission was a nonresponder to first-line full-course DAA. Here, we report new data with a 7-day prophylaxis protocol (N = 50), as well as cumulative treatment and outcome data on all HCV D+/R- transplants (N = 102).

Correlation of Donor-derived Cell-free DNA With Histology and Molecular Diagnoses of Kidney Transplant Biopsies.

Background: Circulating donor-derived cell-free DNA (cfDNA), a minimally invasive diagnostic tool for kidney transplant rejection, was validated using traditional histology. The molecular microscope diagnostic system (MMDx) tissue gene expression platform may provide increased precision to traditional histology.

Methods: In this single-center prospective study of 208 biopsies (median = 5.

Combined Heart-Liver and Domino Liver Transplantation in Familial Amyloidosis.

Background: Combined heart-liver transplantation (CHLT) is the only curative option for patients with concomitant pathology affecting the heart and liver. In some cases, the native livers of familial amyloidosis (FA) patients may be suitable for domino transplantation into other recipients.

Methods: Retrospective analysis (2013 to 2019) of all CHLT at our center was performed.

Targeting CXCR1/2 in the first multicenter, double-blinded, randomized trial in autologous islet transplant recipients.

Several cytokines and chemokines are elevated after islet infusion in patients undergoing total pancreatectomy with islet autotransplantation (TPIAT), including CXCL8 (also known as interleukin-8), leading to islet loss. We investigated whether use of reparixin for blockade of the CXCL8 pathway would improve islet engraftment and insulin independence after TPIAT. Adults without diabetes scheduled for TPIAT at nine academic centers were randomized to a continuous infusion of reparixin or placebo (double-blinded) for 7 days in the peri-transplant period.

A comparison of the inflammatory response following autologous compared with allogenic islet cell transplantation.

Background: The initial response to islet transplantation and the subsequent acute inflammation is responsible for significant attrition of islets following both autologous and allogenic procedures. This multicentre study compares this inflammatory response using cytokine profiles and complement activation.

Methods: Inflammatory cytokine and complement pathway activity were examined in two cohorts of patients undergoing total pancreatectomy followed either by autologous (n=11) or allogenic (n=6) islet transplantation.
