Liver transplantation after radioembolization in a patient with unresectable HCC.

BACKGROUND: A 58-year-old white man who was being followed by his hepatologist for nonalcoholic steatohepatitis-related liver cirrhosis and portal hypertension and who had been found to have a biopsy-proven hepatocellular carcinoma (HCC) on routine screening, self-referred to our center for a second opinion on the management of his HCC. INVESTIGATIONS: Laboratory investigations, CT scan of the abdomen and chest, bone scan and technetium macroaggregated albumin scan. DIAGNOSIS: The patient had unresectable HCC. MANAGEMENT: The patient underwent two treatments with Yttrium-90 glass microspheres, which were performed as outpatient procedures 1 month and 3 months after diagnosis. He underwent orthotopic liver transplantation (OLT) 1 year after the initial diagnosis of HCC. The post-OLT immunoregimen included OKT3 plus rituximab and high-dose steroids. On discharge from hospital he was on immunosuppressive treatment with tacrolimus. He had de novo autoimmune hepatitis 6 months post-OLT, which was treated with a short course of low-dose steroids and addition of mycophenolate mofetil.

Nonalcoholic fatty liver disease and cardiovascular risk.

Nonalcoholic fatty liver disease (NAFLD) is a very common cause of chronic liver disease in the United States. A large proportion of patients with NAFLD have coexisting metabolic syndrome, a major risk factor for cardiovascular disease. A strong association between NAFLD and cardiovascular disease has been long suspected, and recent studies have confirmed that cardiovascular disease is the single most important cause of mortality in this patient population. NAFLD may pose cardiovascular risk beyond the risk conferred by traditional factors such as dyslipidemia, diabetes, and smoking. Health care providers managing patients with NAFLD should recognize this increased cardiovascular risk and should undertake early, aggressive risk factor modification.

EUS-guided FNA of proximal biliary strictures after negative ERCP brush cytology results.

BACKGROUND: Accurate nonoperative diagnosis of proximal biliary strictures (PBSs) is often difficult. OBJECTIVE: To report our experience with EUS-guided FNA (EUS-FNA) of PBSs following negative or unsuccessful results with brush cytology during ERCP. DESIGN: Retrospective cohort study. SETTING: Single, tertiary referral hospital in Indianapolis, Indiana. PATIENTS: Consecutive subjects from January 2001 to November 2004 who underwent EUS-FNA of a PBS documented by ERCP. INTERVENTIONS: EUS-FNA of PBS. MAIN OUTCOME MEASURES: Performance of EUS-FNA, with the final diagnosis determined by surgical pathology study or the results of EUS-FNA and follow-up. RESULTS: A total of 291 biliary strictures undergoing EUS were identified. Of these, 26 (9%) had PBSs and 2 were excluded. EUS-FNA was not attempted in 1 because no mass was visualized. The second had a PBS seen on magnetic resonance cholangiopancreatography, but no ERCP was performed. Twenty-four patients (14 men; mean age, 68 years) underwent EUS-FNA of a PBS following ERCP brush cytology studies that were either negative/nondiagnostic (20) or unable to be performed (4). EUS visualized a mass in 23 (96%) patients, including 13 in whom previous imaging detected no lesion. EUS-FNA (median, 4 passes; range, 1-11) demonstrated malignancy in 17 of 24 (71%) patients with findings showing adenocarcinoma (15), lymphoma (2), atypical cytology (3), or benign cells (4). No complications were noted. Pathology results from 8 of 24 (33%) patients who underwent surgery showed hilar cholangiocarcinoma (6), gallbladder cancer (1), and a benign, inflammatory stricture (1). The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of EUS-FNA were 77% (95% confidence interval [CI], 54%-92%), 100% (95% CI, 15%-100%), 100% (95% CI, 83%-100%), 29% (95% CI, 4%-71%), and 79% (95% CI, 58%-93%), respectively. LIMITATIONS: Histopathologic correlation of EUS-FNA findings was limited to 8 of 24 (33%) patients who underwent surgery. CONCLUSIONS: EUS-FNA is a sensitive method for the diagnosis of PBSs following negative results or unsuccessful ERCP brush cytology. The low negative predictive value does not permit reliable exclusion of malignancy following a negative biopsy.
