2Grade of donor liver microvesicular steatosis does not affect the postoperative outcome after liver transplantation显示文摘BACKGROUND:The potential effect of graft steatosis on the postoperative liver function is discussed controversially. The present study aimed to evaluate the effect of the donor liver microvesicular steatosis on the postoperative outcome after liver transplantation.METHODS:Ninety-four patients undergoing liver transplantation at the University Hospital Aachen were included in this study. The patient cohort was divided into three groups according to the grade of microvesicular steatosis(MiS):MiS <30%(n=27), MiS 30%-60%(n=41) and MiS >60%(n=26).The outcomes after liver transplantation were evaluated, including the 30-day and 1-year patient and graft survival rates and the incidences of early allograft dysfunction(EAD) and primary nonfunction(PNF). RESULTS:The incidences of EAD and PNF did not differ significantly between the groups. We observed 5 cases of PNF,one occurred in the MiS <30% group and 4 in the MiS 30%-60% group. The 30-day and 1-year graft survivals did not differ significantly between groups. The 30-day patient survival rates were 100% in all groups. The 1-year patient survival rates were 94.4% in the MiS <30% group, 87.9% in the MiS 30%-60% group and 90.9% in the MiS >60% group.CONCLUSION:Microvesicular steatosis of donor livers has no negative effect on the postoperative outcome after liver transplantation.Anne Andert Tom Florian Ulmer Wenzel Schoning Daniela Kroy Marc Hein Patrick Hamid Alizai Christoph Heidenhain Ulf Neumann Maximilian Schmeding 2017Hepatobiliary & Pancreatic Diseases International2017,16,6:7
3Impact of body composition on survival and morbidity after liver resection in hepatocellular carcinoma patients显示文摘Background: Hepatocellular carcinoma is the most common innate liver tumor. Due to improved surgical techniques, even extended resections are feasible, and more patients can be treated with curative intent. As the liver is the central metabolic organ, preoperative metabolic assessment is crucial for risk stratification. Sarcopenia, obesity and sarcopenic obesity characterize body composition and metabolic status. Here we present the impact of body composition on survival after liver resection in patients with hepatocellular carcinoma. Methods: A retrospective database analysis of 70 patients who were assigned for liver resection due to hepatocellular carcinoma was conducted. For assessment of sarcopenia and obesity, skeletal muscle surface area was measured at lumbar vertebra 3 level(L3) in preoperative four-phase contrast enhanced abdominal CT scans, and L3 muscle index and body fat percentage were calculated. Results: Univariate analysis comparing the survival curves using the score test demonstrated superior postoperative overall survival for sarcopenic( P = 0.035) and sarcopenic obese( P = 0.048) patients as well as a trend favoring obese( P = 0.130) subjects. Whereas multivariate analysis could not identify significant difference in postoperative survival regarding sarcopenia, obesity or sarcopenic obesity. Only large tumor size, multifocal disease and male gender were risk factors for long-term survival. Conclusions: Sarcopenia, obesity and sarcopenic obesity are indeed no risk factors for poor postoperative survival in this study. Our data do not support the evaluation of sarcopenia, obesity and sarcopenic obesity before liver resection in hepatocellular carcinoma patients.Andreas Kroh Diane Uschner Toine Lodewick Roman M Eickhoff Wenzel Sch?ning Florian T Ulmer Ulf P Neumann Marcel Binneb?sel 2019Hepatobiliary & Pancreatic Diseases International2019,18,1:5
4Intraoperative perfusion magnetic resonance imaging: Cutting-edge improvement in neurosurgical procedures显示文摘The goal in brain tumor surgery is to remove the maxi-mum achievable amount of the tumor, preventing damage to 'eloquent' brain regions as the amount of brain tumor resection is one of the prognostic factors for time to tumor progression and median survival. To achieve this goal, a variety of technical advances have been in-troduced, including an operating microscope in the late 1950 s, computer-assisted devices for surgical navigation and more recently, intraoperative imaging to incorporate and correct for brain shift during the resection of the lesion. However, surgically induced contrast enhancement along the rim of the resection cavity hampers interpretation of these intraoperatively acquired magnetic resonance images. To overcome this uncertainty, perfusion techniques [dynamic contrast enhanced magnetic resonance imaging(DCE-MRI), dynamic susceptibility contrast magnetic resonance imaging(DSC-MRI)] have been introduced that can differentiate residual tumor from surgically induced changes at the rim of the resec-tion cavity and thus overcome this remaining uncer-tainty of intraoperative MRI in high grade brain tumor resection.Stephan Ulmer 2014World Journal of Radiology2014,6,8:3

6Comparative study of the effects of terlipressin versus splenectomy on liver regeneration after partial hepatectomy in rats显示文摘BACKGROUND: Post-hepatectomy liver failure as a result of insufficient liver remnant is a feared complication in liver surgery. Efforts have been made to find new strategies to support liver regeneration. The aim of this study was to investigate the effects of terlipressin versus splenectomy on postoperative liver function and liver regeneration in rats undergoing 70%partial hepatectomy. METHODS: Seventy-two male Wistar rats were randomly assigned into three groups(n=24 in each group): 70% partial hepatectomy as control(PHC), 70% partial hepatectomy with splenectomy(PHS) or 70% partial hepatectomy with a micropump for terlipressin administration(PHT). Eight rats in each group were sacrificed on postoperative day(POD) 1,3 and 7. To assess liver regeneration, immunohistochemical analysis of liver tissue using bromodeoxyuridine(BrdU) and Ki-67 labeling was performed. Portal venous pressure, serum concentrations of creatinine, urea, albumin, bilirubin and prothrombin time as well as liver-, body-weight and their ratio were determined on POD 1, 3 and 7.RESULTS: The liver-, body-weight and their ratio were not statistically different among the groups. On POD 1, 3 and 7 portal venous pressure in the intervention groups(PHT:8.13 ±1.55, 10.38±1.30, 6.25±0.89 cm H_2O and PHS: 7.50±0.93,8.88 ±2.42, 5.75±1.04 cm H_2O) was lower compared to the control group(PHC: 8.63±2.06, 10.50±2.45, 6.50±2.67 cmH_2O). Hepatocyte proliferation in the intervention groups was delayed, especially after splenectomy on POD 1(Brd U: PHS vs PHC, 20.85% ±13.05% vs 28.11%±10.10%; Ki-67, 20.14%±14.10% vs 23.96% ±11.69%). However, none of the differences were statistically significant.CONCLUSIONS: Neither the administration of terlipressin nor splenectomy improved liver regeneration after 70% partial hepatectomy in rats. Further studies assessing the regulation of portal venous pressure as well as extended hepatectomy animal models and liver function tests will help to further investigate mechanisms of liver regeneration.Tom Florian Ulmer Anne Weiland Georg Lurje Christian Klink Anne Andert Hamid Alizai Christoph Heidenhain Ulf Neumann 2017Hepatobiliary & Pancreatic Diseases International2017,16,5:3
