Recurrence of Hepatocellular Carcinoma after Liver Transplantation: Clinical Patterns and Hierarchy of Salvage Treatments.

Introduction: The multiparametric nature of recurrence of hepatocellular carcinoma (HCC) after liver transplantation (LT) still leads to uncertainty with its practical management. This study aims to characterize the main posttransplant recurrence patterns of HCC and to explore the therapeutic modalities targeting recurrence.

Methods: Consecutive patients who underwent LT for HCC at a single tertiary center were analyzed.

Solid pseudopapillary neoplasms of the pancreas: Multicenter Vasepa study.

Introduction: Solid pseudopapillary tumors (SPT) of the pancreas are rare exocrine neoplasms of the pancreas. Correct preoperative diagnosis is not always feasible. The treatment of choice is surgical excision.

Safe Procedure for Efficient Hydrodynamic Gene Transfer to Isolated Porcine Liver in Transplantation.

Although calcineurin inhibitors are very effective as immunosuppressants in organ transplantation, complete graft acceptance remains as a challenge. Transfer of genes with immunosuppressant functions could contribute to improving the clinical evolution of transplantation. In this sense, hydrodynamic injection has proven very efficacious for liver gene transfer.

Alternative forms of portal vein revascularization in liver transplant recipients with complex portal vein thrombosis.

Background & Aims: Complex portal vein thrombosis (PVT) is a challenge in liver transplantation (LT). Extra-anatomical approaches to portal revascularization, including renoportal (RPA), left gastric vein (LGA), pericholedochal vein (PCA), and cavoportal (CPA) anastomoses, have been described in case reports and series. The RP4LT Collaborative was created to record cases of alternative portal revascularization performed for complex PVT.

Appraising pancreatic fistula in pancreas transplantation: A comprehensive complication index based analysis of postoperative outcomes and predictors of graft survival.

Methods: Consecutive simultaneous pancreas and kidney transplantations were analysed.

Vascular injury during cholecystectomy: A multicenter critical analysis behind the drama.

Background: The management of a vascular injury during cholecystectomy is still very complicated, especially in centers not specialized in complex hepatobiliary surgery.

Methods: This was a multi-institutional retrospective study in patients with vascular injuries during cholecystectomy from 18 centers in 4 countries. The aim of the study was to analyze the management of vascular injuries focusing on referral, time to perform the repair, and different treatments options outcomes.

Machine Learning-Based Analysis in the Management of Iatrogenic Bile Duct Injury During Cholecystectomy: a Nationwide Multicenter Study.

Background: Iatrogenic bile duct injury (IBDI) is a challenging surgical complication. IBDI management can be guided by artificial intelligence models. Our study identified the factors associated with successful initial repair of IBDI and predicted the success of definitive repair based on patient risk levels.

Good post-transplant outcomes using liver donors after circulatory death when applying strict selection criteria: A propensity-score matched-cohort study.

Introduction And Objectives: Outcomes of liver transplantation (LT) with donors after circulatory death (DCD) have been considered suboptimal due to higher rates of ischemic cholangiopathy, especially when the super-rapid recovery (SRR) technique is used. This study aimed to compare the incidence of complications between recipients receiving DCD vs those receiving donors after brain death (DBD) in a large-volume liver transplant centre.

Methods: We performed a retrospective cohort study (LT from January 2015 to December 2018) comparing recipients who underwent a LT with DCD vs.

Pharmacogene Variants Associated with Liver Transplant in a Twelve-Year Clinical Follow-Up.

Some gene polymorphisms have been previously associated individually with tacrolimus efficacy and toxicity, but no long-term study to determine the role of pharmacogene variants in the clinical evolution of liver-transplanted patients has been addressed so far. In the present work, we analyzed the relation between highly-evidenced genetic polymorphisms located in relevant pharmacogenes and the risk of suffering premature death and other comorbidities such as cancer, diabetes mellitus, arterial hypertension, graft rejection, infections and nephrotoxicities in a cohort of 87 patients (8 were excluded due to early loss of follow-up) transplanted at Hospital La Fe in Valencia (Spain) during a 12-year follow-up. Employing a logistic regression model with false discovery rate penalization and Kaplan-Meier analyses, we observed significant association between survival rates and metabolizer genes.

Metabolic syndrome before liver transplantation: does it have an impact on post liver transplantation outcome?

Introduction: Metabolic syndrome (MS) and cardiovascular risk factors are common in liver transplant (LT) candidates and recipients. Cardiovascular events and de novo tumors are increasingly common causes of mortality in liver transplant recipients. The aim of this study were (i) assess the prevalence of MS in LT recipients and its growth over the years and (ii) determine if the presence of MS pre-LT is associated with a higher risk of post-LT cardiovascular events (CVE), de novo tumors or early and late survival.

Abdominal normothermic regional perfusion in controlled donation after circulatory determination of death liver transplantation: Outcomes and risk factors for graft loss.

Postmortem normothermic regional perfusion (NRP) is a rising preservation strategy in controlled donation after circulatory determination of death (cDCD). Herein, we present results for cDCD liver transplants performed in Spain 2012-2019, with outcomes evaluated through December 31, 2020. Results were analyzed retrospectively and according to recovery technique (abdominal NRP [A-NRP] or standard rapid recovery [SRR]).

Results after 13 years of kidney-pancreas transplantation in type 1 diabetic patients in Comunidad Valenciana.

Introduction: Simultaneous pancreas-kidney (SPK) transplant is a proven option of treatment for patients with type 1 diabetes mellitus and related end-stage renal disease, who are candidates for kidney transplantation. The results from the beginning of SPK transplant program in Comunidad Valenciana are presented.

Methods: Descriptive, retrospective, and single-center study of the pancreas transplant performed at the Hospital Universitari i Politècnic La Fe, from September 2002 to December 2015.

From conventional two-stage hepatectomy to ALPPS: Fifteen years of experience in a hepatobiliary surgery unit.

Background: Hepatectomy in patients with large tumor load may result in postoperative liver failure and associated complications due to excessive liver parenchyma removal. Conventional two-stage hepatectomy (TSH) and associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) technique are possible solutions to this problem. Colorectal liver metastases (CRLM) is the most frequent indication, and there is a need to assess outcomes for both techniques to improve surgical and long-term oncological outcomes in these patients.

Pancreatic metastases from renal cell carcinoma. Postoperative outcome after surgical treatment in a Spanish multicenter study (PANMEKID).

Background: Renal Cell Carcinoma (RCC) occasionally spreads to the pancreas. The purpose of our study is to evaluate the short and long-term results of a multicenter series in order to determine the effect of surgical treatment on the prognosis of these patients.

Methods: Multicenter retrospective study of patients undergoing surgery for RCC pancreatic metastases, from January 2010 to May 2020.

Late complications of pancreas transplant.

To summarize the long-term complications after pancreas transplantation that affect graft function, a literature search was carried out on the long-term complications of pancreatic transplantation, namely, complications from postoperative 3 mo onwards, in terms of loss of graft function, late infection and vascular complications as pseudoaneurysms. The most relevant reviews and studies were selected to obtain the current evidence on these topics. The definition of graft failure varies among different studies, so it is difficult to evaluate, a standardized definition is of utmost importance to know the magnitude of the problem in all worldwide series.
