RESUMO
One of the concerns specific to minimally invasive donor hepatectomy (MIDH) is the prolonged time required for graft extraction after completion of the donor hepatectomy (donor warm ischemia time [DWIT]). There has never been an objective evaluation of minimally invasive donor hepatectomy-DWIT on allograft function in living donor liver transplantation. We evaluated the effect of DWIT following robotic donor hepatectomy (RDH) on recipient outcomes and compared them with a matched cohort of open donor hepatectomy (ODH). Demographic, perioperative, and recipient's postoperative outcome data for all right lobe (RL)-RDH performed between September 2019 and July 2023 were analyzed and compared with a propensity score matched cohort (1:1) of RL-ODH from the same time period. Of a total of 103 RL-RDH and 446 RL-ODH, unmatched and propensity score matched analysis (1:1) revealed a significantly longer DWIT in the RDH group as compared to the ODH group (9.33 ± 3.95 vs 2.87 ± 2.13, P < .0001). This did not translate into any difference in the rates of early allograft dysfunction (EAD), biliary complications, major morbidity, or overall 1-and 3-month survival. The receiver operating characteristic curve analysis threshold for DWIT-early allograft dysfunction was 9 minutes (area under receiver operating characteristic: 0.67, sensitivity = 80%, specificity = 53.8%). We show that prolonged DWIT within an acceptable range in RDH does not have deleterious effects on short-term recipient outcomes. Further long-term studies are required to confirm our findings, especially with regard to nonanastomotic biliary complications.
RESUMO
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. METHODS: All consecutive patients who underwent liver transplants from January 2010 till December 2019 by our transplant team in the state of Tamil Nadu, India, were included in the study. The program was established initially at the primary hospital in the year 2010 and with the evolution of the initial experience, transplant programs were expanded to the others hospital from the year 2015. Preoperative clinical data, intraoperative characteristics, and posttransplant outcomes of DDLT were analyzed from our prospective database. RESULTS: A total of 362 DDLTs (331 adults, 31 children) were performed at 11 centers. Median (range) model for end-stage liver disease score was 16 (6-39). Forty-eight split, 11 combined liver kidney, and 4 auxiliary DDLTs were performed. One-, 3-, and 5-y survival was 87.2%, 80.4%, and 76.6% in adults and 80.6%, 80.6%, and 80.6% in children, respectively. CONCLUSIONS: In a country where over 80% of the LTs are performed as LDLT, we provide the first report of a heartening trend of increasing number of DDLT programs being established with excellent 5-y outcomes.
RESUMO
INTRODUCTION: Hepatic artery complications (HACs), such as a thrombosis or stenosis, are serious causes of morbidity and mortality after paediatric liver transplantation (LT). This study will investigate the incidence, current management practices and outcomes in paediatric patients with HAC after LT, including early and late complications. METHODS AND ANALYSIS: The HEPatic Artery stenosis and Thrombosis after liver transplantation In Children (HEPATIC) Registry is an international, retrospective, multicentre, observational study. Any paediatric patient diagnosed with HAC and treated for HAC (at age <18 years) after paediatric LT within a 20-year time period will be included. The primary outcomes are graft and patient survivals. The secondary outcomes are technical success of the intervention, primary and secondary patency after HAC intervention, intraprocedural and postprocedural complications, description of current management practices, and incidence of HAC. ETHICS AND DISSEMINATION: All participating sites will obtain local ethical approval and (waiver of) informed consent following the regulations on the conduct of observational clinical studies. The results will be disseminated through scientific presentations at conferences and through publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER: The HEPATIC registry is registered at the ClinicalTrials.gov website; Registry Identifier: NCT05818644.
