BACKGROUND: Self-expandable metallic stents (SEMSs) are widely used for palliation of malignant gastric outlet obstruction (GOO). A common complication of their use, however, is stent obstruction caused by tumor ingrowth or hyperplasia. The covered SEMS was designed to prevent these problems. OBJECTIVE: We compared the performance of uncovered and covered ...

Over half of patients diagnosed with esophageal cancer are unsuitable for curative resection. A significant proportion of these patients will subsequently require palliative stenting to alleviate dysphagia. There is growing consensus in the literature that the deployment of a Self-Expanding Metal Stent is the optimum stenting strategy; however, it remains ...

BACKGROUND: The placement of self-expandable metallic stents (SEMS) is known to be effective palliative treatment of malignant gastroduodenal obstruction. There are two types of SEMS--covered and uncovered--each with its own advantages and disadvantages. This study was conducted to compare between the clinical outcomes of covered and uncovered stents in patients ...

CONTEXT: Debate still continues as to the effects of preoperative biliary stents on postoperative complications after pancreaticoduodenectomy. Some studies have documented increased wound infection rates, while others have not. The importance of this issue rests on whether these postoperative complications are detrimental enough to not recommend preoperative chemoradiation in the ...

BACKGROUND: Malignant gastric outlet obstruction (GOO) is commonly seen in patients with advanced gastric-, pancreatic-, duodenal, hepatobiliary or metastatic malignancies. Ten to 25% of patients with pancreatic cancer will develop duodenal obstruction during the course of the disease. Duodenal stenting with self-expandable metal stents is an alternative treatment to surgical ...

Very late angiographic stent thrombosis (VAST) is a known serious complication of drug-eluting stents (DESs). Most VAST events occur shortly after the discontinuation of aspirin and/or clopidogrel. This case is unique in that the patient had recently discontinued only aspirin and involves simultaneous VAST of 2 separate stents. Although the ...

Patients with drug-eluting stents appear to be at increased risk of thrombosis beyond 30 days (late) or even 1 year (very late) after stent placement. Patients with recent placement of drug-eluting stents who are receiving dual-antiplatelet therapy pose a challenge in the perioperative period. Current guidelines recommend discontinuation of clopidogrel ...

Despite the use of distal embolic protection devices (DEPs) in carotid artery (CA) stenting, an appreciable risk of stroke exists, particularly in symptomatic patients. The mechanism of embolic events is possibly related to microembolization of atherothrombotic débris that remains or forms on the stent struts. This study evaluated the safety ...
