Self expandable metal stent can be used both as palliative treatment for malignant colorectal obstruction and as a bridge to surgery in patients with potentially resectable colorectal cancer. Here, we report a case of successful relief of malignant stomal obstruction using a metal stent. A 56-year-old man underwent loop ileostomy and was given palliative chemotherapy for ascending colon cancer ...
We compared the efficacy and safety of drug-eluting stents with that of bare-metal stents in patients who experienced acute ST-segment-elevation myocardial infarction (STEMI) and underwent primary percutaneous coronary intervention. To do this, we performed a meta-analysis of 13 randomized controlled trials in which drug-eluting stents were compared with bare-metal stents in STEMI patients. The...
Patients with diabetes mellitus have less favourable outcomes after percutaneous coronary intervention (PCI) than non-diabetics. We performed a subgroup analysis of the multicentre RAVEL trial to examine the impact of the sirolimus-eluting stent (SES) on outcomes in diabetic patients. The RAVEL study randomized 238 patients to treatment with either sirolimus-eluting or bare metal stents. Forty-...
BACKGROUND Guidelines recommend that noncardiac surgery be delayed until 30 to 45 days after bare-metal stent implantation and 1 year after drug-eluting stent implantation. METHODS AND RESULTS We used linked registry data and population-based administrative health care databases to conduct a cohort study of 8116 patients (≥40 years of age) who underwent major elective noncardiac surgery in On...
OBJECTIVES To examine the safety and effectiveness of cobalt-chromium everolimus eluting stents compared with bare metal stents. DESIGN Individual patient data meta-analysis of randomised controlled trials. Cox proportional regression models stratified by trial, containing random effects, were used to assess the impact of stent type on outcomes. Hazard ratios with 95% confidence interval for ...
OBJECTIVES This study sought to evaluate the potential utility of a novel polyethylene terephthalate micronet mesh-covered stent (MGuard) in patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI). BACKGROUND Suboptimal myocardial reperfusion after PCI in STEMI is common and results in increased infarct size and mortality. The...
BACKGROUND Female sex was reported to be associated with lower risk for midterm restenosis and repeat revascularization after bare-metal stent implantation. However, the influence of sex on very long-term outcomes after bare-metal stent implantation has not been yet reported. METHODS AND RESULTS Among the 9877 patients in the multicenter Coronary Revascularization Demonstrating Outcome study ...
sheared guidewire following failed endoscopic ultrasound-guided pancreatic duct drainage A 50-year-old man with a retained sheared guidewire in the main pancreatic duct and pancreatic parenchyma was referred for recurrent pancreatitis. He had previously undergone a pancreaticoduodenectomy for pancreatic hemangioma and was experiencing recurrent pancreatitis due to pancreaticojejunostomy strictu...
Metal stent insertion to relieve malignant gastroduodenal obstruction is an effective alternative to surgery, but there are some problems associated with existing metal stents for malignant gastroduodenal obstruction. Common complications of covered and uncovered stents are migration and obstruction, respectively. To date, there are several practice-improved stents, such as partially covered, d...
BACKGROUND Since the introduction of stents in 1994, improved clinical results have boosted the development of coronary angioplasty in Chile. Drug eluting stents, that have a reduced rate of restenosis, are being increasingly used. AIM To assess the acute and long-term results of bare metal stent implantation. PATIENTS AND METHODS Acute and long-term clinical, procedural and angiographic re...
