Objective: To investigate the alteration of HBV markers in liver allograft of HBV related recipients pre and post liver transplantation under Lamivudine or combination of Lamivudine with HBIG prophylaxis and explore the mechanism of HBV de nova infection in liver allograft after orthotopic liver transplantation, as well as seek to establish a optimal prophylactic protocol.
Methods: The serial liver biopsy specimens of 90 liver allograft and sera of 78 liver transplant recipients during operation and after 1 week, 1 month, 3 months, 6 months, 12 months, 24 months post transplantation have been collected and detected for HBV markers with enzyme-linked radioimmunoassay, fluorescent quantitative assay for HBV-DNA in serology and with immunohistochemistry stain, HBV-DNA in situ hybridization in histology for detection of HBV markers in liver allograft samples.
Results: Whether recipients with active replicative or inactive replicative HBV preoperatively, none of positive HBV-DNA, HBsAg and HBcAg in 100% liver biopsy specimens with HBV-DNA hybridization in situ and immunohistochemistry stains in histology within 2 hours after reperfusion.
Conclusion: Whatever HBV replicative status the recipients have before surgery, no evidence of HBV particles direct invasion to the liver allograft from HBV related cirrhotics during operation under current prophylactic measures. However, the further supposed mechanism and its significance in HBV de nova infection of liver allograft remained to be disclosed further.

Background: Long-term outcomes of HBV nucleic acid test (NAT)-positive (+) allograft use in seronegative liver transplant (LT) and kidney transplant (KT) recipients remains unknown despite being incorporated into practice by select centers. This study compares long-term outcomes between HBV NAT+ and NAT-negative (-) allografts in seronegative recipients.
Study Design: All recipients of an HBV core antibody-positive (HBcAb+) LT or KT were prospectively evaluated at a single transplant center from 6/2015-3/2023 and compared by NAT status.

In controlled donation after circulatory death (DCD) liver transplantation, ischemia-reperfusion injury is linked to post-reperfusion syndrome (PRS), acute kidney injury (AKI), and early allograft dysfunction (EAD). Normothermic regional perfusion (NRP) and normothermic machine perfusion (NMP) are techniques that mitigate ischemic injury and associated complications. In this single centre retrospective study, we compared early transplant outcomes of DCD livers undergoing direct procurement (DP) and static cold storage (DCD-DP-SCS), NRP procurement with SCS (DCD-NRP-SCS), or DP with NMP (DCD-DP-NMP).

Background: Locally advanced pancreatic adenocarcinomas (LA-PDAC) are more frequently operated now than in the past because of new regimen chemotherapy and improvement in surgical technique. Resection of the coeliac trunk (CT) during pancreatoduodenectomy (PD) or total pancreatectomy (TP) is not routinely done owing to the risk of liver and gastric ischaemia. In this video, a patient with LA-PDAC underwent TP with CT resection and retrograde gastric revascularization through the distal splenic artery.

Objectives: Liver transplant is the most effective therapeutic option for patients with end-stage liver disease, nonalcoholic steatohepatitis, and acute liver failure. We evaluated whether the percentage of hepatic fat percentage affected transplant outcomes to determine whether livers with varying severity of macrosteatosis should be considered suitable for donation.
Materials And Methods: We analyzed data from 381 patients with liver failure who received liver transplant at Montaseriyeh Hospital in Mashhad, Iran, between 2013 and 2022.

Background: During orthotopic liver transplantation, allograft reperfusion is a dynamic point in the operation and often requires vasoactive medications and blood transfusions. Normothermic machine perfusion (NMP) of liver allografts has emerged to increase the number of transplantable organs and may have utility during donation after circulatory death (DCD) liver transplantation in reducing transfusion burden and vasoactive medication requirements.
Methods: This is a single-center retrospective study involving 226 DCD liver transplant recipients who received an allograft transported with NMP (DCD-NMP group) or with static cold storage (DCD-SCS group).
