    Sepsis-induced microcirculatory alterations contribute to tissue hypoxia and organ dysfunction. In addition to its plasma volume expanding activity, human serum albumin (HSA) has anti-oxidant and anti-inflammatory properties and may have a protective role in the microcirculation during sepsis. The concentration of HSA infused may influence these effects. We compared the microcirculatory effects of the infusion of 4% and 20% HSA in an experimental model of sepsis

    BACKGROUND: Prevalence and incidence of hepatic haemangioma are estimated from autopsy series only. Although benign and generally asymptomatic, hepatic haemangioma can cause serious complications. AIMS: The aim of the study was to assess the prevalence of hepatic haemangioma and to attempt to quantify the risk of major complications such as spontaneous rupture. METHODS: We retrospectively analyzed the radiology database of a Regional University Hospital over a 7-year period: the radiological records of 83,181 patients who had an abdominal computed tomography or magnetic resonance scan were reviewed. Diagnoses made at imaging were reviewed and related to clinical course. RESULTS: Hepatic haemangioma was diagnosed in 2071 patients (2.5% prevalence). In 226 patients (10.9%), haemangioma had diameter of 4 cm or more (giant haemangioma). The risk of bleeding was assessed on patients without concomitant malignancies. Spontaneous bleeding occurred in 5/1067 patients (0.47%). All 5 patients had giant haemangioma: 4 had exophytic lesions and presented with haemoperitoneum; 1 with centrally located tumour experienced intrahepatic bleeding. CONCLUSION: Giant haemangiomas have a low but relevant risk of rupture (3.2% in this series), particularly when peripherally located and exophytic. Surgery might be considered in these cases

    Continuous erector spinae plane block for pain management in laparoscopic liver resection: case report

    Pain after liver resection can be difficult to manage. Epidural anesthesia (EA) isaneffective technique inpain control inthis surgery. However, postoperative coagulopathy and hypotension due to autonomic nervous system block in high-risk patients, may result that the EA is an inadequate analgesic technique in according to enhanced recovery after surgery (ERAS) recommendations for liver surgery. Regional block techniques have been recommended for liver surgery in ERAS guidelines. Erector spinae plane (ESP) block is a recent block described for thoracic and abdominal surgeries and provides both somatic and visceral analgesia. We describe a high-risk patient with cardiac dysfunction and Parkinson's disease who underwent laparoscopic right liver resection for hepatocellular carcinoma. Satisfactory intra and postoperative analgesia was achieved by a combined continuous ESP block, transversus abdominis plane (TAP), and oblique subcostal TAP blocks. Surgery and postoperative period was uneventful. No opioids were administered during hospitalization. A combined of thoracic and abdominal wall blocks can be an effective approach for intra and postoperative analgesia in highrisk patients undergoing laparoscopic liver resection. Further clinical research is recommended to establish the effectiveness of the ESP block as an analgesic technique in this surgery

    Metastatic breast cancer mimicking a hilar cholangiocarcinoma: case report and review of the literature

    No full text
    Breast cancer is the most common tumor in women and the first cause of death for malignancy in the female population. Bile ducts are not among the common sites of metastasis from breast cancer; few cases of obstructive jaundice due to metastatic breast cancer have been described in the literature and they mostly resulted from widespread liver metastases that eventually involved the bile ducts. We report an exceptional case of metastatic infiltration of the extrahepatic bile ducts in absence of liver metastases

    Transoesophageal echocardiography during liver transplantation

    Liver transplantation (LT) has become the standard of care for patients with end stage liver disease. The allocation of organs, which prioritizes the sickest patients, has made the management of liver transplant candidates more complex both as regards their comorbidities and their higher risk of perioperative complications. Patients undergoing LT frequently display considerable physiological changes during the procedures as a result of both the disease process and the surgery. Transoesophageal echocardiography (TEE), which visualizes dynamic cardiac function and overall contractility, has become essential for perioperative LT management and can optimize the anaesthetic management of these highly complex patients. Moreover, TEE can provide useful information on volume status and the adequacy of therapeutic interventions and can diagnose early intraoperative complications, such as the embolization of large vessels or development of pulmonary hypertension. In this review, directed at clinicians who manage TEE during LT, we show why the procedure merits a place in challenging anaesthetic environment and how it can provide essential information in the perioperative management of compromised patients undergoing this very complex surgical procedure

    Predictive factors of short term outcome after liver transplantation: A review

    Liver transplantation represents a fundamental therapeutic solution to end-stage liver disease. The need for liver allografts has extended the set of criteria for organ acceptability, increasing the risk of adverse outcomes. Little is known about the early postoperative parameters that can be used as valid predictive indices for early graft function, retransplantation or surgical reintervention, secondary complications, long intensive care unit stay or death. In this review, we present state-of-the-art knowledge regarding the early post-transplantation tests and scores that can be applied during the first postoperative week to predict liver allograft function and patient outcome, thereby guiding the therapeutic and surgical decisions of the medical staff. Post-transplant clinical and biochemical assessment of patients through laboratory tests (platelet count, transaminase and bilirubin levels, INR, factor V, lactates, and Insulin Growth Factor 1) and scores (model for end-stage liver disease, acute physiology and chronic health evaluation, sequential organ failure assessment and model of early allograft function) have been reported to have good performance, but they only allow late evaluation of patient status and graft function, requiring days to be quantified. The indocyanine green plasma disappearance rate has long been used as a liver function assessment technique and has produced interesting, although not univocal, results when performed between the 1(th) and the 5(th) day after transplantation. The liver maximal function capacity test is a promising method of metabolic liver activity assessment, but its use is limited by economic cost and extrahepatic factors. To date, a consensual definition of early allograft dysfunction and the integration and validation of the above-mentioned techniques, through the development of numerically consistent multicentric prospective randomised trials, are necessary. The medical and surgical management of transplanted patients could be greatly improved by using clinically reliable tools to predict early graft function

    Common variable immunodeficiency (CVID) is the most common primary immunodeficiency disease and is a heterogeneous group of antibody deficiency syndromes characterized by hypogammaglobulinemia, recurrent bacterial infections, and frequent autoimmune manifestations. Liver transplantation (LT) is rarely performed in patients with CVID and associated end-stage liver disease
