Introduction
Liver transplantation has dramatically improved survival in patients with end-stage liver disease and hepatocellular carcinoma. However, long-term outcomes are often compromised by complications such as graft rejection, recurrent disease, or de novo liver pathology leading to fibrosis and cirrhosis. Traditionally, monitoring relies on invasive methods like liver biopsy, but increasing attention is being given to Non-invasive tests as safer alternatives.
Problem Statement
The role and optimal application of non-invasive tests in post-transplant liver assessment remain unclear and are not yet standardized in routine clinical practice.
Summary
This review emphasizes the emerging role of non-invasive tests in monitoring liver graft health after transplantation. NITs—including tools for assessing fibrosis, steatosis, and portal hypertension—have already transformed management in native liver disease, but their translation into the post-transplant setting is still evolving.
The authors highlight that NITs can potentially detect early graft dysfunction, reducing the need for repeated biopsies and enabling closer, safer monitoring. However, interpretation in the transplant setting is more complex due to factors such as immunosuppression, vascular changes, and mixed etiologies of graft injury.
A key takeaway is the need for contextual interpretation—NIT results should not be used in isolation but integrated with clinical, biochemical, and imaging data. Despite current limitations, NITs offer a promising pathway toward personalized, longitudinal graft surveillance, allowing earlier intervention and improved long-term outcomes.
Overall, this review supports a gradual shift from invasive to non-invasive monitoring strategies in post-transplant care, while emphasizing the need for further validation and standardized protocols.

Introduction: Perioperative bleeding remains a major challenge during orthotopic liver transplantation (OLT), largely due to hyperfibrinolysis and coagulation abnormalities. Although tranexamic acid (TXA) effectively reduces bleeding in several surgical settings, its routine prophylactic use during...
Introduction: Liver transplantation is limited by a shortage of suitable donor organs. Current viability assessment relies on needle biopsy, which samples only a small portion of the liver and may miss important regional pathology. This...
Introduction: Bleeding remains a major challenge during liver transplantation despite advances in surgical techniques, anesthesia, and perioperative care. Antifibrinolytic agents have long been used to reduce intraoperative blood loss and transfusion requirements. However, evolving transplant...
Introduction: The demand for liver transplantation continues to exceed the availability of deceased donor organs, resulting in prolonged waiting times and preventable waitlist mortality. This perspective discusses how living donor liver transplantation (LDLT) can complement...
Introduction: Pediatric liver transplantation has achieved excellent survival rates, shifting the focus from graft survival alone to optimising long-term health, growth, neurodevelopment, and quality of life. This updated guideline provides evidence-based recommendations for comprehensive care...
