Liver transplantation: Do not abandon T-tube drainage-a multicentric retrospective study of the ARCHET research group.

Biliary complications remain a real issue in liver transplantation (LT). Despite meta-analyses, the anastomosis technique, especially the use of biliary drain as T-Tube drain (TT) or transcystic drain, remains controversial. This study conducted by the ARCHET research group examine the incidence and types of biliary complications (BC) after LT according to the presence or absence of a biliary drain.

Aborted pancreatoduodenectomy after extensive vascular dissection in patients with pancreatic cancer: a word of caution.

Background: Difficulties in distinguishing fibrosis from tumor in borderline and locally advanced pancreatic adenocarcinoma (PDAC) justify surgical exploration to assess resectability. This issue is especially relevant after neoadjuvant treatments (NAT) prior to pancreaticoduodenectomy (PD) although outcomes of aborted PD are unknown.

Objectives: This study aimed to evaluate early outcomes after aborted PD in patients with PDAC.

HOPE Mitigates Ischemia-Reperfusion Injury in Ex-Situ Split Grafts: A Comparative Study With Living Donation in Pediatric Liver Transplantation.

Optimizing graft preservation is key for ex-situ split grafts in pediatric liver transplantation (PSLT). Hypothermic Oxygenated Perfusion (HOPE) improves ischemia-reperfusion injury (IRI) and post-operative outcomes in adult LT. This study compares the use of HOPE in ex-situ partial grafts to static cold storage ex-situ partial grafts (SCS-Split) and to the gold standard living donor liver transplantation (LDLT).

Right Ex-situ split grafts for adult liver transplantation - A Multicenter Benchmarking Analysis.

Objective: To analyse outcomes after adult right ex-situ split graft liver transplantations (RSLT) and compare with available outcome benchmarks from whole liver transplantation (WLT).

Summary Background Data: Ex-situ SLT may be a valuable strategy to tackle the increasing graft shortage. Recently established outcome benchmarks in WLT offer a novel reference to perform a comprehensive analysis of results after ex-situ RSLT.

Correlation between antifungal clinical practices and a new clinical decision support system ANTIFON-CLIC® for the treatment of invasive candidiasis: a retrospective multicentre study.

Background: Invasive candidiasis is still recognized as a major cause of morbidity and mortality. To support clinicians in the optimal use of antifungals for the treatment of invasive candidiasis, a computerized decision support system (CDSS) was developed based on institutional guidelines.

Objectives: To evaluate the correlation of this newly developed CDSS with clinical practices, we set-up a retrospective multicentre cohort study with the aim of providing the concordance rate between the CDSS recommendation and the medical prescription (NCT05656157).

Tacrolimus Monitoring in Liver Transplant Recipients, Posttransplant Cholestasis: A Comparative Between 2 Commercial Immunoassays and a Liquid Chromatography-Tandem Mass Spectrometry Method.

Background: Cholestasis commonly occurs after orthotopic liver transplantation. It can be extrahepatic because of mechanical obstruction or intrahepatic because of various causes. During cholestasis episodes, blood concentrations of tacrolimus (TAC) metabolites may increase, potentially affecting TAC concentrations measured by immunoassays.

Comprehensive bile acid pool analysis during ex-vivo liver perfusion in a porcine model of ischemia-reperfusion injury.

Bile acids (BA) are key for liver regeneration and injury. This study aims at analyzing the changes in the BA pool induced by ischemia-reperfusion (IRI) and investigates the impact of hypothermic oxygenated perfusion (HOPE) on the BA pool compared to static cold storage (SCS). In a porcine model of IRI, liver grafts underwent 30 min of asystolic warm ischemia followed by 6 h of SCS (n = 6) ± 2 h of HOPE (n = 6) and 2 h of ex-situ warm reperfusion.

A Single Preservation Solution for Static Cold Storage and Hypothermic Oxygenated Perfusion of Marginal Liver Grafts: A Preclinical Study.

Background: Hypothermic oxygenated perfusion (HOPE) improves outcomes of marginal liver grafts. However, to date, no preservation solution exists for both static cold storage (SCS) and HOPE.

Methods: After 30 min of asystolic warm ischemia, porcine livers underwent 6 h of SCS followed by 2 h of HOPE.

Case Report: Successful liver transplantation after achieving complete clinical remission of advanced HCC with Atezolizumab plus Bevacizumab combination therapy.

Background: Atezolizumab plus Bevacizumab combination therapy has recently emerged as the new standard of care for unresectable HCC. Significant tumor burden reduction can be observed under that treatment, raising the question of liver transplantation (LT). The safety of another immune checkpoint inhibitor (ICI), nivolumab, is unclear in the pre-transplant setting.

End-ischemic hypothermic oxygenated perfusion for extended criteria donors in liver transplantation: a multicenter, randomized controlled trial-HOPExt.

Background: Given the scarce donor supply, an increasing number of so-called marginal or extended criteria donor (ECD) organs are used for liver transplantation. These ECD liver grafts are however known to be associated with a higher rate of early allograft dysfunction and primary non-function because of a greater vulnerability to ischemia-reperfusion injury. The end-ischemic hypothermic oxygenated machine perfusion (HOPE) technique may improve outcomes of liver transplantation with ECD grafts by decreasing reperfusion injury.

Transarterial chemoembolization followed by moderately hypofractionated radiotherapy in hepatocellular carcinoma: Long-term results of RTF3 regimen.

Purpose: In early-stage hepatocellular carcinoma (HCC) patients merely fit for surgery, transarterial chemoembolization (TACE) achieve low long-term disease control. We evaluated the efficacy and safety of its combination with moderately hypofractionated radiotherapy (hRT) using RTF3 regimen.

Material And Methods: Between 2006 and 2016, 61 consecutive patients treated in our single expert center for a Barcelona Clinic Liver Cancer (BCLC) A HCC by TACE followed by hRT 3Gy/fraction were retrospectively included.

Ex-situ graft reduction (H67) during hypothermic oxygenated perfusion to prevent large-for-size syndrome in liver transplantation-A technical report.

In this report, we discuss several technical and anatomical details of ex-situ H67 reduction of liver grafts during hypothermic oxygenated perfusion to prevent large-for-size syndrome in the case of anthropometric graft-recipient mismatch.

Liver transplantation and hepatocellular carcinoma: is TIPS deleterious? A multicentric retrospective study of the ARCHET research group with propensity score matching.

Purpose: A transjugular intrahepatic portosystemic shunt (TIPS) before the liver transplantation (LT) has been considered a contraindication in cases of hepatocellular carcinoma (HCC) because of the risk of tumour growth. We aimed to assess the impact of TIPS on incidental HCC and oncological outcomes in transplanted patients with pre-existing HCC.

Methods: All consecutive transplanted patients for cirrhosis who had a previous TIPS with or without HCC were included.

From large-for-size to large-for-flow: A paradigm shift in liver transplantation.

Liver graft-recipient matching remains challenging, and both morphologic and hemodynamic characteristics have been shown to be relevant indicators of post-transplant outcomes. However, no combined analysis is available to date. To study the impact of both morphologic and hemodynamic characteristics of liver grafts on transplantation outcomes, we retrospectively evaluated all consecutive 257 liver transplantations with prospective hemodynamic measurements from 2017 to 2020 in a single-center perspective.

Role of neoadjuvant chemoradiotherapy in liver transplantation for unresectable perihilar cholangiocarcinoma: multicentre, retrospective cohort study.

Background: The Mayo protocol for liver transplantation in patients with unresectable perihilar cholangiocarcinoma is based on strict selection and neoadjuvant chemoradiotherapy. The role of neoadjuvant chemoradiotherapy in this scenario remains unclear. The aim of this study was to compare outcomes after transplantation for perihilar cholangiocarcinoma using strict selection criteria, either with or without neoadjuvant chemoradiotherapy.

Optimizing graft-recipient size matching in adolescent liver transplantation: Don't forget ex situ right posterior sectionectomy.

Background: Graft-recipient size matching is a major challenge in pediatric liver transplantation, especially for adolescent recipients. Indeed, adolescents have the lowest transplantation rate among pediatric recipients, despite prioritization policies and the use of split grafts. In case of an important graft-recipient size mismatch, ex situ graft reduction with right posterior sectionectomy (RPS) may optimize the available donor pool to benefit adolescent recipients.

Necrosis as a strong independent prognostic factor required in the implementation of pathological reporting for pancreatic adenocarcinoma resection specimens.

Introduction: Pancreatic ductal adenocarcinoma (PDAC) is a major public health issue with an incidence/mortality ratio reaching 98 %. Only 15-20 % of patients with PDAC can undergo surgery. Following PDAC surgical resection, 80 % of patients will experience local or metastatic recurrence of this disease.
