Introduction
Early allograft dysfunction (EAD) remains a major challenge after living donor liver transplantation (LDLT), often driven by portal hyperperfusion and small-for-size graft physiology. Splenectomy has been used to modulate portal flow, but its routine use is controversial due to surgical risks. The graft-to-spleen volume ratio (GSVR) has emerged as a potential physiological marker to better select patients who may benefit from splenectomy.
Problem Statement
There is no clear, objective criterion to guide selective splenectomy in LDLT. Empirical or routine splenectomy may expose patients to unnecessary risks, while omission in high-risk patients may lead to EAD, thrombocytopenia, ascites, and graft dysfunction. A reliable, reproducible strategy is needed to identify patients who truly benefit from splenic modulation.
Summary
This prospective study validated a GSVR-based selective splenectomy strategy in 141 LDLT recipients. Splenectomy was performed when GSVR ≤0.70 or in high-risk settings (ABO incompatibility, older donor, high portal pressure).
Introduction: Bacterial infections remain a major cause of morbidity after liver transplantation despite advances in perioperative care. Synbiotics, combining probiotics and prebiotics, have been proposed to reduce postoperative infections by restoring gut microbiota and strengthening...
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...
