Background And Aims: Fully covered self-expandable metal stents (FCSEMSs) are widely used in benign upper gastrointestinal (GI) conditions, but stent migration remains a limitation. An over-the-scope clip (OTSC) device (Stentfix {SF], Ovesco Endoscopy) for stent anchoring has recently been developed. The aim of this study was to evaluate the effect of OTSC fixation on FCSEMS migration rate.

Introduction: Chronic infection with hepatitis C virus is a risk factor for developing atheromatous plaques, although the possible effect of virus clearance is unknown. Our aim was to determine whether or not subclinical atheromatosis improved and there was any modification in the composition of the plaques 12 months after eradication of hepatitis C virus by direct-acting antiviral agents.

Materials And Methods: Prospective study that included 85 patients with chronic hepatitis C virus infection in different stages of fibrosis who were on direct-acting antiviral agents.

Background: Pivotal phase studies of telaprevir (TLV) and boceprevir (BOV) showed 10-56% rates of early treatment interruption. However, there have been no reports on the sustained virological response (SVR) rates of these patients.

Aim: To assess the SVR rate in a large cohort of patients who discontinued triple therapy with TLV or BOV for reasons other than stopping rules and to identify variables predicting SVR.
