Transient elastography (TE) is the reference method to obtain liver stiffness measurements (LSM), but no results are obtained in 3.1% and unreliable in 15.8%. We assessed the applicability and diagnostic accuracy of TE re-evaluation using M and XL probes. From March 2011 to April 2012 868 LSM were performed with the M probe by trained operators (50-500(More)
Hemangioma of the small bowel is a rare disease, the preoperative diagnosis of which is extremely difficult. Although it is an uncommon cause of gastrointestinal bleeding, this is usually the most frequent clinical manifestation causing chronic anemia or acute hemorrhage. We present a case of cavernous hemangioma localized in the jejunum in a young patient(More)
BACKGROUND Data are scarce on the natural history of chronic hepatitis C (CHC) in patients with mild hepatitis C who did not respond to anti-viral therapy. AIM To predict the risk of progression to cirrhosis, identifying patients with the more urgent need for therapy with effective anti-virals. METHODS A cohort of 1289 noncirrhotic CHC patients treated(More)
BACKGROUND AND AIM Transient elastography is the reference method for liver stiffness measurement (LSM) in the general population, having lower applicability in obese patients. We evaluated the applicability and diagnostic accuracy of the M and XL probes in overweight/obese patients to establish the most appropriate approach. METHODS From May 2013 to(More)
INTRODUCTION & AIMS Cryopreservation of serum samples is a standard procedure for biomedical research in tertiary centers. However, studies evaluating the long-term biological stability of direct liver fibrosis markers using cryopreserved samples are scarce. METHODS We compared the stability of hyaluronic acid (HA), tissue inhibitor of metalloproteinases(More)
AIM To investigate the clinical impact of capsule endoscopy (CE) after an obscure gastrointestinal bleeding (OGIB) episode, focusing on diagnostic work-up, follow-up and predictive factors of rebleeding. METHODS Patients who were referred to Hospital del Mar (Barcelona, Spain) between 2007 and 2009 for OGIB who underwent a CE were retrospectively(More)
OBJECTIVE The clinical value of thyrotropin receptor antibodies for the differential diagnosis of thyrotoxicosis induced by pegylated interferon-alpha remains unknown. We analyzed the diagnostic accuracy of thyrotropin receptor antibodies in the differential diagnosis of thyrotoxicosis in patients with chronic hepatitis C (CHC) receiving pegylated(More)
