Living donor liver transplantation

BACKGROUND AND AIMS: Endoscopic multiple plastic stents are an established first-line treatment for anastomotic biliary stricture (ABS) management after liver transplantation (LT). Fully covered self-expandable metallic stents (FCSEMSs) have recently been used with favorable outcomes, but long-term treatment outcomes remain an issue for ABS. We evaluated the long-term outcomes of FCSEMS for the management of refractory ABS after LT. METHODS: We reviewed the prospectively collected and maintained endoscopic retrograde cholangiography database at Asan Medical Center to retrieve consecutive post-LT ABS cases that underwent an endoscopic FCSEMS placement between August 2009 and August 2019 after MPS placement failure...

BACKGROUND: Preoperative imaging evaluation of liver volume and hepatic steatosis for the donor affects transplantation outcomes. However, computed tomography (CT) for liver volumetry and magnetic resonance spectroscopy (MRS) for hepatic steatosis are time consuming. Therefore, we investigated the correlation of automated 3D-multi-echo-Dixon sequence magnetic resonance imaging (ME-Dixon MRI) and its derived proton density fat fraction (MRI-PDFF) with CT liver volumetry and MRS hepatic steatosis measurements in living liver donors...

BACKGROUND AND AIMS: Liver regeneration is essential for the preservation of homeostasis and survival. Bile acids (BAs)-mediated signaling is necessary for liver regeneration, but BAs levels need to be carefully controlled to avoid hepatotoxicity. We studied the early response of the BAs-fibroblast growth factor 19 (FGF19) axis in healthy individuals undergoing hepatectomy for living donor liver transplant. We also evaluated BAs synthesis in mice upon partial hepatectomy (PH) and acute inflammation, focusing on the regulation of cytochrome-7A1 (CYP7A1), a key enzyme in BAs synthesis from cholesterol...

BACKGROUND: Evidence for the long-term use of antiplatelet drugs to prevent hepatic vascular complications (HVC) is scarce in liver transplantation (LT). METHODS: From national claim data, LT recipients (about 80 % of living donor LT [LDLT]) without graft loss, HVC, or cardiovascular events within 1 year, were classified into those who took antiplatelets for ≥1 year (n = 1744) and for <1 year (n = 1975). Outcomes were compared after the 1-postoperative year index time point...

BACKGROUND: Paucity of deceased donor livers has resulted in a 10-fold rise in living donor liver transplantations (LDLTs) performed in India over the past decade. Nonetheless, number of deceased donor liver transplantation (DDLT) performed has improved with the establishment of simplified legal framework for certification of brain death and organ donation. In this study, we present our outcomes of DDLT performed at various centers, comparing their outcomes and provide a snapshot of the increasing number of DDLT across the state over the years...

BACKGROUND: Metabolic factors have a significant role in the morbidity and mortality associated with chronic liver disease. The pancreas has a central role in metabolism and metabolic risk factors but has been largely ignored in liver transplantation. Small pancreas volume has been demonstrated in pathologic conditions such as type 1 and 2 diabetes. METHODS: This study assessed abdominal imaging before and after liver transplantation to determine if liver transplantation induces changes in pancreas volume in living donor liver transplant recipients...

AIM: Although the incidence of overweight and obese recipients and donors is increasing worldwide, few reports have focused on outcomes of preoperative weight reduction (WR) in living-donor liver transplantation (LDLT). We therefore examined the outcomes and the impact of WR on the postoperative course. METHODS: We analyzed 217 consecutive LDLT procedures performed from 2017 to 2022. We divided the recipients and donors into a WR group and non-WR group. RESULTS: Twenty-two recipients (10...

BACKGROUND: Living donor liver transplant (LDLT) is based on the principle of double equipoise. Organ shortage in Asian countries has led to development of high-volume LDLT programs with good outcomes. Safety of live liver donor is the Achilles heel of LDLT program and every effort should be made to achieve low morbidity and near zero mortality rates. METHODS: We retrospectively analyzed our prospectively maintained donor morbidity data (outcomes) of 177 donors in a new transplant program setup in western India by an experienced surgeon...

The hepatic blood supply and its several homeostatic and pathologic processes has always been a matter of great interest. Many views commonly held today are derived from an earlier era, but major reorientations have occurred recently in almost all aspects of knowledge of the role and regulation of hepatic blood flow. Moreover, with the advent of liver transplantation (LT), especially living donor LT (LDLT) there has been a resurgence of interest in attempting to comprehend this deceptively simple topic. It is nonetheless important to concede that even though our knowledge on the practical modulation of hepatic hemodynamics has expanded enormously, there still remain the need to explore the depths of our remaining ignorance to further improve outcomes in LDLT...

Background Living donor liver transplantation (LDLT) offers the opportunity to decrease waitlist time and mortality for patients with AILD; autoimmune hepatitis (AIH), primary biliary cholangitis (PBC), and primary sclerosing cholangitis (PSC). We compared the survival of patients with a potential live donor (pLDLT) on the waitlist vs. no potential live donor (pDDLT), on an intention-to-treat (ITT) basis. Methods Our retrospective cohort study investigated adults with AILD listed for liver transplant at our program between 2000 and 2021...

Liver transplantation is the only lifesaving procedure for children with end-stage liver disease. The field is however heterogenic with various graft types, recipient age and weight and underlying diseases. Despite recently improved overall outcomes and the expanded use of living donors, waiting list mortality remains unacceptable particularly in small children and infants. Based on the known negative effect of elevated donor age, higher body mass index, and prolonged cold ischemia time, the number of available donors for pediatric recipients is limited...

Following its initial execution in November 2015, pure laparoscopic donor hepatectomy (PLDH) has gained acceptance as a conventional practice at Seoul National University Hospital (SNUH). It is noteworthy that a significant proportion of cases entail full right hepatectomies, which are acknowledged to be technically demanding. As expertise and knowledge have been accrued, the pure laparoscopic technique has been extended to encompass liver recipients as a viable option in SNUH. The aim of this review is to present the developmental progression of PLDH, with a focus on pure laparoscopic donor right hepatectomy (PLDRH), at SNUH...

Partial hepatectomy is an essential surgical technique used to treat advanced liver diseases such as liver tumors, as well as for performing liver transplants from living donors.However, postoperative complications such as bleeding, abdominal adhesions, wound infections, and accelerated liver regeneration pose significant challenges and increase morbidity and mortality rates.We have developed a self-repairing mixed hydrogel (O5H2/Cu2+/SCCK) containing bioactive cell factors (SCCK) derived from Human Umbilical Cord Mesenchymal Stem Cells (HUMSCs) treated with the traditional Chinese remedy Tanshinone IIA (TSA)...

BACKGROUND: Living donor lobar lung transplantation is a life-saving procedure for critically ill patients. This requires 2 healthy donors exposed to risks and without medical benefit. Therefore, the donor's safety and minimal postoperative complications are crucial. This study aimed to investigate the short-term outcomes and identify the risk factors affecting these outcomes. METHODS: The data of 175 living donors enrolled between 1998 and 2022 were analyzed. Donors were divided into era 1 (1998-2009) and era 2 (2010-2022)...

Living donor liver transplantation (LDLT) has emerged as a favorable alternative to deceased donor liver transplantation, significantly reducing waitlist mortality, particularly in Asian countries with very low deceased organ donation rates. Asan Medical Center (AMC) in South Korea has pioneered innovative LDLT surgical techniques and become established as an extremely high-volume center for LDLT. This retrospective study analyzed 6000 consecutive LDLT procedures, including 510 dual-graft procedures, performed at AMC between December 1994 and January 2021...

The role of infections in the pathogenesis of autoimmune diseases has long been recognized and reported. In addition to infectious agents, the internal composition of the "friendly" living bacteria, (microbiome) and its correlation to immune balance and dysregulation have drawn the attention of researchers for decades. Nevertheless, only recently, scientific papers regarding the potential role of transferring microbiome from healthy donor subjects to patients with autoimmune diseases has been proposed. Fecal microbiota transplantation or FMT, carries the logic of transferring microorganisms responsible for immune balance from healthy donors to individuals with immune dysregulation or more accurately for our paper, autoimmune diseases...

Background : This study evaluated the effectiveness of short fully covered self-expanding metal stents (FCSEMS) with an anti-migration design in treating benign biliary strictures (BBS) not related to living donor liver transplantation (LDLT). Methods : A retrospective analysis was conducted on 75 patients who underwent FCSEMS insertion for BBS management. Stents were initially kept for 3 months and exchanged every 3 months until stricture resolution. Adverse events and stricture recurrence after FCSEMS removal were assessed during follow-up...

BACKGROUND: Multiple adult studies have investigated the role of older donors (ODs) in expanding the donor pool. However, the impact of donor age on pediatric liver transplantation (LT) has not been fully elucidated. METHODS: UNOS database was used to identify pediatric (≤18 years) LTs performed in the United States during 2002-22. Donors ≥40 years at donation were classified as older donors (ODs). Propensity analysis was performed with 1:1 matching for potentially confounding variables...
