Recurrent Bacteremia and Cholangitis From Eroded Hepatic Artery Pseudoaneurysm Coil Into the Common Hepatic Duct: A Rare Indication for Liver Transplantation.

Liver transplant may be necessary to manage infectious complications from severe structural biliary disease. In this report, we describe a 71-year-old woman with history of coil-embolized hepatic artery pseudoaneurysm who subsequently developed biliary obstruction resulting from coil erosion into the common hepatic duct. Resultant complications included recurrent cholangitis, bacteremia, and numerous hepatic abscesses.

Kidney Transplantation in ≤15 kg Children: Outcomes and Prognostic Indicators-A Review of the Organ Procurement and Transplantation Database.

Background: Approximately 2500 pediatric patients are awaiting kidney transplantation in the United States, with <5% comprising those ≤15 kg. Transplant in this cohort is often delayed by center-based growth parameters, often necessitating transplantation after the initiation of dialysis. Furthermore, prognostication remains somewhat ambiguous.

CHALF Score: A Novel Tool to Rapidly Risk Stratify Children in Need of Liver Transplant Evaluation During Acute Liver Failure.

Background: Pediatric acute liver failure (PALF) can require emergent liver transplantation (LT, >25%) or lead to death (~15%). Existing models cannot predict clinical trajectory or survival with native liver (SNL). We aimed to create a predictive model for PALF clinical outcomes based on admission variables.

Evaluation of technical urinary tract complications in kidney transplantation recipients with a prolonged dialysis history.

Background: The kidney transplant waiting list continues to expand, resulting in prolonged dialysis times exceeding 8 years before transplantation in some regions. The relationship between long-term dialysis and urinary tract complications after kidney transplant remains largely unexplored. This study aims to evaluate post-kidney transplant complications in patients with a history of prolonged dialysis.

Living donor liver paired exchange between pediatric and adult recipients due to donor graft size mismatch.

Living donor liver transplantation is an effective means to decrease organ shortage. However, many potential living donors are currently being denied due to ABO incompatibility or inadequate donor liver volume. Liver paired exchange (LPE) provides a practical solution to overcome these obstacles, and yet the first case of LPE in the United States was only recently reported in 2020.

Model for End-Stage Liver Disease/Pediatric End-Stage Liver Disease exception policy and outcomes in pediatric patients with hepatopulmonary syndrome requiring liver transplantation.

Hepatopulmonary syndrome (HPS) is associated with increased waitlist mortality in liver transplantation (LT) candidates. Children with HPS are granted Model for End-Stage Liver Disease (MELD)/Pediatric End-Stage Liver Disease (PELD) exception points for waitlist prioritization in the United States based on criterion developed for adults. In this study, the impact of this MELD/PELD exception policy on post-LT survival in children was examined.

Clinical Value of Surveillance Biopsies in Pediatric Liver Transplantation.

Although pediatric liver transplantation (LT) results in excellent long-term outcomes, a high incidence of early acute cellular rejection and late graft fibrosis persists. Routine measurement of allograft enzymes may not reliably detect rejection episodes, identify candidates for immunosuppression minimization, or indicate allograft fibrosis. Surveillance biopsies (SBs) can provide valuable information in this regard, but their role in pediatric LT is not fully established.

Pediatric kidney transplantation, a technical update.

Purpose Of Review: Pediatric kidney transplantation is the definitive therapy for infants and children suffering from renal failure. It is a distinct endeavor demanding specialized care for optimal results. This includes a dedicated preoperative workup accounting for unique predisposing urologic conditions, specialized surgical techniques, and careful hemodynamic monitoring and maintenance.

Surgical shunts for extrahepatic portal vein obstruction in pediatric patients: a systematic review.

Background: Extrahepatic portal vein obstruction (EHPVO) causes portal hypertension in noncirrhotic children. Among surgical treatments, it is unclear whether the meso-Rex shunt (MRS) or portosystemic shunt (PSS) offers lower post-operative morbidity and superior patency over time. Our objective was to evaluate long-term outcomes comparing MRS and PSS for pediatric patients with EHPVO.

Pediatric kidney transplantation in the United States.

Purpose Of Review: Pediatric kidney transplantation has made great strides over the preceding years. It has become an accepted and successful remedy for thousands of patients worldwide. For best outcomes, it must be viewed and treated as a distinct entity from adult transplantation with focus on the unique challenges particular to its cohort.

Biliary Internal Stents and Biliary Complications in Adult Liver Transplantation.

Background: Biliary complications in liver transplantation (LT) can cause significant morbidity or even lead to a potential graft loss and patient mortality. Oftentimes biliary internal stents (ISs) are used at the time of LT to lower the risk for or prevent these biliary complications; however, their efficacy and outcomes remain controversial.

Methods: A retrospective cohort study was conducted on all of the adult patients who underwent a deceased-donor LT (DDLT) with an end-to-end choledococholedocostomy.

Should living donor liver transplant selection be subject to the same restrictions as deceased donor transplant?

Purpose Of Review: In the United States, most of the liver allografts come from deceased donors, and our current liver recipient selection process is heavily centered on the ethical principle of utility to maximize the net benefit to the liver recipient community as a group rather than individuals due to the organ scarcity. Although living donor liver transplantation contributes less than 5% of total liver transplant in the United States, these living donor recipients are being subjected to the same selection process designed to benefit the group as a whole rather than the individuals. We would like to examine if these recipients who have living donors should be subjected to the same selection process.

Reno-portal shunt for liver transplant, an alternative inflow for recipients with grade III-IV portal vein thrombosis: Tips for a better outcome.

Introduction: Portal vein thrombosis (PVT) poses an extremely difficult problem in cirrhotic patients who are in need of a liver transplant. The prevalence of PVT in patients with cirrhosis ranges from 0.6% to 26% Nery et al.

Pseudolymphoma (reactive lymphoid hyperplasia) of the liver: A clinical challenge.

Reactive lymphoid hyperplasia (RLH), also known as pseudolymphoma or nodular lymphoid lesion of the liver is an extremely rare condition, and only 51 hepatic RLH cases have been described in the literature since the first case was described in 1981. The majority of these cases were asymptomatic and incidentally found through radiological imaging. The precise etiology of hepatic RLH is still unknown, but relative high prevalence of autoimmune disorder in these cases suggests an immune-based liver disorder.
