Filter by:Extended hepatectomies of 4 or more segments are complicated by high rates of morbidity and mortality, mainly related to hepatic liver failure. Nowadays, preoperative assessment of the future remnant liver is just performed through its volumetric measurement by computed tomography. Nevertheless, this volumetric assessment does not reflect the hepatocellular function of the future remnant liver that can be disturbed in case of vascular and/or biliary obstruction, chemotherapy-induced liver injuries or steatosis in overweight patients. Literature data (albeit originating from a single centre in Europe) have suggested that (99m)Tc-mebrofenin hepatobiliary scintigraphy could be useful in evaluating the function of the future remnant liver. The aim of this prospective multicentric study is to determine the predictive value of hepatobiliary scintigraphy in assessing the risk of postoperative liver failure of extended hepatectomies of 4 or more segments in noncirrhotic liver.
Background: In mainland China, the development of pediatric liver transplantation (LT) has lagged behind that of adult LT during the past two decades, but it has been progressing immensely in recent years. Renji hospital(shanghai) is currently the largest pediatric transplant center in mainland China. Aim and method: This study is performed for establishment of key techniques for pediatric LT in mainland China, including the indications and timing for pediatric LT, the criteria for donor selections, living donor LT planning, prevention and treatment for posttransplant complications, long-term follow-up management et al.
This ring aimed to preserve an intra-hepatic porto-caval gradient inferior to 5 mm Hg during and after major hepatectomy (48h) to protect the liver during the initial phases of liver regeneration. Morphological features of MID-AVRTM allow its intra corporeal opening and percutaneously removal after an balloon inflation with 5 ml of physiological serum. MID-AVRTM had been developed in pig where it had proved its efficiency to improve liver function after 75% hepatectomy and its capacity to be removed percutaneously. Aim of this feasibility study (Phase I/II) is to prove in series of 3 evaluable patients (Phase A) then 6 evaluable patients (Phase B) that MID-AVRTM could be used in human without deleterious consequence. In phase A, MID-AVRTM is dispose around the portal vein before and during a major hepatectomy performed on healthy liver and removed before abdominal closure. If phase A results confirmed that MID-AVRTM well modulates portal pressure and is easily opened and removed by acute inflation, the phase B will be started. In phase B, MID-AVRTM will be dispose around the portal vein before major hepatectomy on healthy liver and conserved 48 hours before to be removed percutaneously at the operating room.
This study evaluates the Granulocyte colony-stimulating factor (G-CSF) in the treatment of Acute on Chronic Liver Failure in adult. Half participants will receive G-CSF and standard treatment in combination, while half participants will receive standard treatment.
Donation after cardiac death (DCD) livers are increasingly utilised in liver transplantation but concerns exist regarding negative results. Ischemic cholangiopathy (IC) is damage to one or more bile ducts probably caused by inadequate blood flow or a failure of biliary epithelium to regenerate. It typically presents weeks to months after liver transplantation, is often refractory to treatment and can result in a requirement for re-transplantation. Although IC is more common following DCD liver transplantation, it is otherwise very difficult to predict and the underlying pathogenesis is poorly understood. The aim of this study is to correlate microRNA (miRNA) levels and markers of senescence in liver and bile duct biopsies taken during liver transplantation with the incidence of IC following liver transplantation.
The purpose of this study is to help determine whether cystatin C is a more sensitive laboratory measurement for renal function in cirrhotic patients.
Transient elastography is novel non-invasive method for assessment of hepatic fibrosis in patients with chronic liver disease, by measuring liver stiffness. Transient elastography is a user friendly technique that can be easily performed at bedside or in outpatient clinic with immediate results and good reproducibility. Liver stiffness values ranges from 2.5 to 75 kPa with lower values <6kPa suggest no fibrosis where as higher values above 14kPa suggests cirrhosis. In the present study the investigators hypothesis that the investigators can differentiate ACLF and acute severe viral hepatitis based on fibroscan as patients with underlying fibrosis with superadded inflammation would have higher fibroscan value than when patient have only inflammation with no underlying fibrosis and hence the investigators can avoid unnecessary test in such subgroup.
HBV-related liver failure (HBV-LF), a dramatic clinical syndrome, is characterized with massive necrosis of liver cells. Liver transplantation might be the most effective therapy for HBV-LF. However, there are a lot of problems such as lack of donors, surgical complications, transplant rejection, and high cost, which could limit the application of liver transplantation. It is demonstrated that mesenchymal stem cells could directionally differentiate into hepatocytes and cholangiocytes in injured liver, as well as reduce inflammation of the liver by immune regulation. In this study, we assess the safety and efficacy of human bone marrow and umbilical cord mesenchymal stem cells transplantation for patients with HBV-LF.
Liver failure (LF) is a dramatic clinical syndrome with massive necrosis of liver cells. Although liver transplantation provides an option to cure patients suffering with LF, lack of donors, postoperative complications, especially rejection, and high cost limit its application. Previous study showed that bone marrow derived mesenchymal stem cells (BM-MSCs) the novel and promising therapeutic strategy, BM-MSCs can replace hepatocytes in injured liver, and effectively rescue experimental liver failure and contribute to liver regeneration. Plasma exchange (PE) can improve internal environment by removing endotoxin, it helps the liver regeneration and functional recovery and make UC-MSC differentiation into hepatocyte like cells, and exert immunomodulatory function. In this study, safety and efficacy of human umbilical cord mesenchymal stem cells (UC-MSCs) transplantation combined with plasma exchange (PE) for patients with liver failure caused by hepatitis B Virus will be evaluated.
The purpose of this study is to compare lactate clearance in patients with severe sepsis and septic shock according to the presence of hepatic dysfunction.
