OBJECTIVE The aim of this study was to assess the sensitivity of MR imaging in the diagnosis of liver hemochromatosis and its ability to quantify hepatic iron concentration (HIC). SUBJECTS AND METHODS MR images were prospectively obtained in 58 patients suspected to have hemochromatosis. We used a scanner with a 0.5-T magnet and two sequences:(More)
PURPOSE To evaluate the efficacy of percutaneous transhepatic biliary drainage in the treatment of biliary leaks. MATERIALS AND METHODS Sixteen patients with a biliary leak involving either the common bile duct (n = 12), the biliary confluence (n = 2), or a hepaticojejunal anastomosis (n = 2) were treated by means of percutaneous transhepatic biliary(More)
BACKGROUND & AIMS Abnormalities of fat in the mesentery including adipose tissue hypertrophy and fat wrapping have been long recognized on surgical specimens as characteristic features of Crohn's disease. However, the importance, origin, and significance of the mesenteric fat hypertrophy in this chronic inflammatory disease are unknown. Peroxisome(More)
BACKGROUND Despite cure of primary aldosteronism by surgical resection, hypertension persists postoperatively in 30% to 50% of patients. The aim of this study was to determine factors influencing long-term outcome of blood pressure after unilateral adrenalectomy for primary aldosteronism. METHODS Records of 100 patients who underwent unilateral(More)
OBJECTIVES To evaluate the efficacy of arterial embolization (EMB) in the management of bleeding pancreatic pseudocysts or pseudoaneurysms and to assess the possible indication for secondary surgery. DESIGN Retrospective review with a mean follow-up of 60 months (range, 18-125 months). SETTING Tertiary care center, university hospital. PATIENTS The(More)
BACKGROUND Liver iron content (LIC) assessment by magnetic resonance imaging (MRI) is validated but not standardized. In a single center, we tried to assess the accuracy of a specific, simple MRI procedure adapted to high LIC from a well-established simple and routine procedure known to quantify LIC. METHODS In 27 cases of monthly transfused patients, we(More)
The purpose of this study was to assess the usefulness of helical CT in depicting the location of acute lower gastrointestinal bleeding. A three-phase helical CT of the abdomen was performed in 24 patients referred for acute lower gastrointestinal bleeding. The diagnosis of the bleeding site was established by CT when there was at least one of the following(More)
BACKGROUND Sorafenib increases median survival and time to radiological progression in patients with advanced hepatocellular carcinoma, but its benefit for Child-Pugh B patients remains uncertain. AIM To evaluate the safety and efficacy of sorafenib in real-life clinical practice conditions and to assess the influence of Child-Pugh class B on safety and(More)
