Objective: To evaluate the efficacy and safety of ABO-incompatible liver transplantation in adult patients with fulminant hepatitis B.
Methods: The clinical data of 97 cases of adult liver transplantation for fulminant hepatitis B were retrospectively analyzed. The patients were grouped as ABO-identical (ABO-Id, n = 58), ABO-compatible (ABO-C, n = 19) and ABO-incompatible (ABO-In, n = 20). The rates of rejection, infection, biliary tract complications, vascular complications, and patient and graft survivals were compared among 3 groups.
Results: The 3-month, 1-year and 3-year graft survival rates were 87.9%/77.6%/65.3% in ABO-Id group, 84.2%/73.7%/66.5% in ABO-C group and 50.0%/35.0%/33.3% in ABO-In group respectively. There were significant differences between ABO-Id and ABO-In (P < 0.05). The incidences of rejection, infection, vascular complications and biliary tract complications were 8.6%, 20.7%, 3.4% and 6.9% in ABO-Id group, 35%, 60%, 20% and 30% in ABO-In group (P < 0.05) and 10.5%, 26.3%, 5.3% and 10.5% respectively in ABO-C group (P > 0.05).
Conclusion: ABO-C liver transplantation is an important therapeutic option in adult patients with acute liver failure awaiting an emergency procedure. ABO-In transplantation can be used only for life-rescuing in patients with fulminant hepatitis since it is associated with a higher risk of rejection, infection, vascular thrombosis, ischemic bile duct complications and poor patient and graft survival.

Duodenal-jejunal bypass ameliorates MASLD in rats by regulating gut microbiota and bile acid metabolism through FXR pathways.

Department of Gastroenterology, The First Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou, Zhejiang, China.
Background: Although bariatric and metabolic surgical methods, including duodenal-jejunal bypass (DJB), were shown to improve metabolic dysfunction-associated steatotic liver disease (MASLD) in clinical trials and experimental rodent models, their underlying mechanisms remain unclear. The present study therefore evaluated the therapeutic effects and mechanisms of action of DJB in rats with MASLD.
Methods: Rats with MASLD were randomly assigned to undergo DJB or sham surgery.
INTERNATIONAL NORMALIZED RATIO AND ACTIVATED PARTIAL THROMBOPLASTIN TIME DO NOT PREDICT PLASMA TRANSFUSION IN LIVER TRANSPLANTATION.

Background: Blood loss during liver transplantation (LT) remains a major concern associated with increased morbidity and reduced patient and graft survival. The high complexity of the procedure associated with the multifaceted origin of the bleeding urges early identification of high-risk patients and proper monitoring of hemostasis disorders in order to improve results. The accuracy of international normalized ratio (INR) and activated partial thromboplastin time (aPTT) to evaluate coagulation status in cirrhotic patients has been doubted.

Background: Cholangiocarcinoma (CCA) is a rare neoplasm, with high mortality, originating in the bile ducts. Its incidence is higher in Eastern countries due to the endemic prevalence of liver parasites. Factors such as metabolic syndrome, smoking, and pro-inflammatory conditions are also linked to the disease.

Background: Patients undergoing liver transplantation (LT) are at risk of perioperative neurocognitive dysfunction (PND), which significantly affects the patients' prognosis.
Objective: This study used machine learning (ML) algorithms with an aim to extract critical predictors and develop an ML model to predict PND among LT recipients.
Methods: In this retrospective study, data from 958 patients who underwent LT between January 2015 and January 2020 were extracted from the Third Affiliated Hospital of Sun Yat-sen University.

Although living donor liver transplantation has evolved, small-for-size syndrome remains a feared complication. Achieving optimal outflow for the graft with limited donor risk is possible with an experienced team and different techniques. Here we describe the technical aspects of living donor liver transplantation using a right lobe graft, including the different types of grafts, venous reconstructions and the importance of preoperative workup.
