Development of a liver graft assessment expert machine-learning system: when the artificial intelligence helps liver transplant surgeons.

Background: The complex process of liver graft assessment is one point for improvement in liver transplantation. The main objective of this study is to develop a tool that supports the surgeon who is responsible for liver donation in the decision-making process whether to accept a graft or not using the initial variables available to it.

Material And Method: Liver graft samples candidate for liver transplantation after donor brain death were studied.

Impact of a Donor Age >75 Years on the Survival of Liver Transplant Recipients.

Background: An organ shortage is the reason why it is necessary to expand the pool of donors, which can be achieved by using elderly donors. The main goal of this study is to analyze the outcomes of liver transplant (LT) when it is performed with donors older than 75 years.

Methods: We carried out a retrospective case-control study (N = 212) that included LTs with donors older than 75 years (group A, n = 106 cases) that were performed in our center between the years 2010 and 2020.

Cumulative exposure to tacrolimus and incidence of cancer after liver transplantation.

Cancer is the leading cause of death after liver transplantation (LT). This multicenter case-control nested study aimed to evaluate the effect of maintenance immunosuppression on post-LT malignancy. The eligible cohort included 2495 LT patients who received tacrolimus-based immunosuppression.

Risk Factors for No Valid Liver Graft. Multivariate Study Based on the Variables Included in the Donation Protocol of the National Trasplant Organisation.

Introduction: Among the strategies designed to optimize the number of existing liver grafts for transplantation, the implementation of the graft assessment process is one of the least explored. The main objective is to identify the risk factors presented by liver donors for «NO validity». Secondly, we analyzed the coincidence between the surgeon's assessment and that of the anatomo-pathologist in the invalid donors.
