OBJECTIVE We wanted to evaluate the efficacy of stent placement using the coaxial technique with a stiff, long introducer sheath in patients with technical failure using an angiographic catheter for the obstructions proximal to the descending colon. MATERIALS AND METHODS Self-expandable metallic stent placement was attempted under fluoroscopy-guidance in 77 consecutive patients who had malign...

PURPOSE To report our early experience with thermo-expandable urethral stents (Memokath) for the management of recurrent urethral stricture and to assess the efficacy of urethral stents. MATERIALS AND METHODS Between March 2012 and February 2013, 13 patients with recurrent urethral stricture after several attempts with direct visual internal urethrotomy (DVIU) or failed urethroplasty underwen...

Dysphagia is the most common presenting symptom in patients with esophageal malignancy and contributes significantly to weight loss and malnourishment. An increasing number of patients with locally advanced esophageal cancer undergo treatment with neoadjuvant chemoradiotherapy (CRT) before surgery because this has been shown to improve survival. Neoadjuvant CRT is, however, associated with acut...

Endobronchial stent placement is a novel therapy for treatment of iatrogenic tracheal tears. A review of the available literature shows surgery and long-term intubation being the established treatment strategy. We describe the case of a 64-year-old woman with a tracheal rupture following endotracheal intubation for routine surgery. Pneumo-mediastinum and chest pain were the predominant symptoms...

Stents are metallic scaffolds that are deployed within a diseased segment of coronary artery to establish and then maintain a widely patent lumen. Just 6 years after the 1994 approval of the balloon-expandable Palmaz-Schatz slotted tube stent in the United States, stents are utilized in upwards of 80% of interventions and have revolutionized catheter-based treatment. Given the rapid evolution i...

Since its introduction in the early 1990s, the self-expandable metal stent (SEMS) has been increasingly used for the management of malignant colorectal obstruction, not only as a palliative method but also as a preoperative treatment in surgical candidates. However, more recently, concerns have been raised over stent complication rates. Early complications include pain, perforation, and rectal ...

Biliary stenting via endoscopic retrograde cholangiopancreatography has greatly improved the quality of patient care over the last 30 years. Plastic stent occlusion limits the life span of such stents. Attempts to improve plastic stent patency duration have mostly failed. Metal stents (self-expandable metal stents [SEMSs]) have therefore replaced plastic stents, especially for malignant biliary...

We describe a Takayasu arteritis patient who was admitted because of an abdominal aortic stenosis, further complicated by the presence of a stenotic right renal artery located in the area of the aortic stenosis. After treatment of the renal stenosis with a 4 × 15 mm Driver stent, a 16 × 60 self-expandable nitinol stent (OptiMed) was deployed through the stenosis of the abdominal aorta. Even tho...

UNLABELLED Currently, laparoscopic sleeve gastrectomy is one of bariatric surgeries most commonly performed in the world. The most frequent complications of surgeries of this type, with the highest mortality rate, include bleeding into the GI tract and peritoneal cavity, and sleeve staple line leaks. These severe complications prolong the hospital stay, and often are a cause of patient's death....

PURPOSE To evaluate the safety and clinical effectiveness of a covered retrievable expandable nitinol stent for the treatment of malignant tracheobronchial stricture and/or esophagorespiratory fistula (ERF). MATERIALS AND METHODS With fluoroscopic guidance, stents were placed in 35 symptomatic patients with malignant tracheobronchial stricture and/or ERF in most cases caused by lung or esopha...
