BACKGROUND: Home parenteral nutrition (HPN) has become a common therapy, with tunneled central venous catheters (CVCs) being preferred for its administration. Peripherally inserted central catheters (PICCs) are not currently recommended for long-term HPN, although evidence to support this statement is scarce. The authors aimed to evaluate the outcomes of HPN, ...

BACKGROUND: Theoretically, the side-by-side bilateral placement of metal stents may be technically easier than stent-in-stent bilateral placement in stent revision. However, side-by-side placement can be technically challenging, as the deployment of the first stent can preclude the passage of the second stent. AIM: We explored the technical feasibility and revision ...

BACKGROUND/PURPOSE: It is generally thought that an internal short stent placed across the pancreaticojejunostomy (PJ) following pancreatoduodenectomy (PD) usually passes spontaneously through the rectum thereafter; however, we experienced some patients who presented with pancreatitis and cholangitis owing to delayed defecation of the stent. The purpose of this study was to ...

Common bile duct stenting is widely performed for bridging benign and malignant obstructions. A major limitation is early stent occlusion making regular stent exchange necessary. Covalent binding of glycosaminoglycanes to polyethylene stents proved to reduce encrustation in urological implants. Since development of urological and biliary stent occlusion shows parallels, the ...

BACKGROUND: Fully covered self-expandable metal stents (FCSEMS) have been used as a rescue therapy for several benign biliary tract conditions (BBC). Long-term stent placement commonly occurs, and prolonged FCSEMS placement is associated with the majority of the complications reported. This study evaluated the duration of stenting and the efficacy and ...
Pagnotta Paolo - - 2012
BACKGROUND: Although the inability to cross the chronic total occlusion (CTO) with a guidewire is the most common reason for failure, one of the most frustrating situations that may occur during a recanalization procedure is when a guidewire crosses successfully but it is impossible to advance any device over the ...
