Low myo-inositol and high glutamine levels in brain are associated with neuropsychological deterioration after induced hyper-ammonemia.—The neuropsychological effect of hyperammonemia is variable. This study tests the hypothesis that the effect of ammonia on the neuropsychological function in patients with cirrhosis is determined by the ability of the brain(More)
In acute liver failure (ALF), it is unclear whether the systemic inflammatory response associated with intracranial hypertension is related to brain cytokine production. To determine the relationship of brain cytokine production with severity of intracranial hypertension in ALF patients. We studied 16 patients with ALF. All patients were mechanically(More)
Background: Minimal hepatic encephalopathy (MHE) is common in cirrhosis but its pathophysiologic basis remains undefined. We evaluated whether the presence of MHE was associated with severity of liver disease, ammonia levels or the presence of inflammation and assessed factors determining neuropsychological deterioration accompanying induction of(More)
Patients with liver disease have reduced urea synthesis capacity resulting in reduced capacity to detoxify ammonia in the liver. The contribution of the gut to the hyperammonemic state observed during liver failure is mainly due to portacaval shunting and not the result of changes in the metabolism of ammonia in the gut. Small intestinal synthesis of(More)
Ammonia is thought to be central in the pathogenesis of hepatic encephalopathy and has been of importance to generations dating back to the early Egyptians. Hippocrates 2500 years ago described ‘encephalopathy’ simply translated as ‘inside head suffering.’ Over 1500 papers have been written on hepatic encephalopathy since 1966, but only a minority of these(More)
This study tests the hypothesis that administration of an oral amino acid load mimicking hemoglobin in patients with cirrhosis of the liver causes deterioration in neuropsychological function and a reduction in regional cerebral perfusion. Eight overnight fasted, metabolically stable cirrhotic patients with no evidence of overt hepatic encephalopathy were(More)
Liver transplantation is the only curative treatment in patients with end-stage liver disease. Neurological complications (NC) are increasingly reported to occur in patients after cadaveric liver transplantation. This retrospective cohort study aims to evaluate the incidence and causes of NC in living donor liver transplant (LDLT) patients in our transplant(More)
Enterocutaneous fistulas (ECF) pose a major challenge to every gastrointestinal (GI) surgeon. Based on earlier studies, a standardized treatment guideline was implemented. The focus of the present study was to assess that guideline and determine prognostic factors for outcome of patients with ECF, and to define a more detailed therapeutic approach including(More)
Postoperative infectious complications (PICs) are associated with significant morbidity after abdominal surgery. Using multivariate analysis of data from a prospective database, our study focused on the risk factors for PICs and the prevention of these complications after hepatectomy, with the goal of improving outcomes and reducing the length of hospital(More)
The application of endobiliary self-expandable metallic stents (SEMS) is considered the palliative treatment of choice in patients with biliary obstruction in the setting of inoperable malignancies. In the presence of SEMS, however, radical surgery is the only curative option when the resectability status is revised in case of malignancies or for overcoming(More)
