Introduction And Objectives: Epigenetic changes represent a mechanism connecting external stresses with long-term modifications of gene expression programs. In solid organ transplantation, ischemia-reperfusion injury (IRI) appears to induce epigenomic changes in the graft, although the currently available data are extremely limited. The present study aimed to characterize variations in DNA methylation and their effects on the transcriptome in liver transplantation from brain-dead donors.

To date, caval sparing (CS) and total caval replacement (TCR) for recipient hepatectomy in liver transplantation (LT) have been compared only in terms of surgical morbidity. Nonetheless, the CS technique is inherently associated with an increased manipulation of the native liver and later exclusion of the venous outflow, which may increase the risk of intraoperative shedding of tumor cells when LT is performed for HCC. A multicenter, retrospective study was performed to assess the impact of recipient hepatectomy (CS vs.

Background: The value of splenectomy for body localization (≥ 5 cm from spleen hilum) of pancreatic ductal adenocarcinoma (B-PDAC) is uncertain. This study assessed spleen-preserving distal pancreatectomy (SPDP) results for B-PDAC.

Patients And Methods: This single-center study included patients who underwent SPDP (Warshaw's technique) or distal splenopancreactomy (DSP) for B-PDAC from 2008 to 2019.

Objective: To investigate whether and how experience accumulation and technical refinements simultaneously implemented in auxiliary orthotopic liver transplantation (AOLT) may impact on outcomes.

Background: AOLT for acute liver failure (ALF) provides the unique chance of complete immunosuppression withdrawal after adequate native liver remnant regeneration but is a technically demanding procedure. Our department is a reference center for ALF and an early adopter of AOLT.

Background & Aims: Patients with non-alcoholic fatty liver disease (NAFLD) have impaired liver regeneration. Liver endothelial cells play a key role in liver regeneration. In non-alcoholic steatohepatitis (NASH), liver endothelial cells display a defect in autophagy, contributing to NASH progression.
