Endoscopic bilateral stenting using conventional metal stents is considered to be technically difficult in patients with malignant hilar bile duct obstruction because the second stent is not easily inserted through the cell of the first stent wall in the bile duct [1]. A variety of new self-expandable metal stents (SEMS) specially designed for stent-in-stent procedures to facilitate bilateral s...
Previous studies reported that ultrathin endoscope (UE) provides endoscopic guidance during insertion of a self-expanding metal stent (SEMS) without fluoroscopic monitoring in patients with upper gastrointestinal stenosis (benign or malignant) or postoperative esophageal leakage. According to the type of SEMS and level of the stenosis, the technique of the procedure is variable. Herein, we repo...
Purpose The present study aimed to determine the safety and efficacy of a drug-coated balloon inflated within a thin-strut self-expanding bare-metal stent in patients with severe and complex femoropopliteal occlusive disease. Methods This prospective study used the Pulsar-self-expanding stent and Passeo-18 Lux drug-coated balloon in patients with severe and complex femoropopliteal occlusive dis...
INTRODUCTION Self-expanding metal stents (SEMS) are successfully being used to acutely relieve obstructing colorectal cancers; yet, their use does not come without complications. PRESENTATION OF CASE We present a case in which a patient with a recurrent obstructing sigmoid carcinoma underwent colonic stenting for acute decompression. Two months after stent placement, an enterocolic fistula fo...
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...
OBJECTIVES The aim of this study was to evaluate the Sparrow sirolimus-eluting stent (Sparrow-SES) against the Sparrow bare-metal stent (Sparrow-BMS) and conventional balloon-expandable bare-metal stent (BMS: Driver/Micro-Driver stent, Medtronic Vascular, Santa Rosa, CA). BACKGROUND The Sparrow stent (Biosensors International, Singapore) consists of a guide wire-based, self-expandable, ultra-...
Stent is a metal mesh tube for opening the obstructed vessels of the body. Ni-Ti alloy is a suitable metal for fabrication of stent due to its potential for applying the appropriate stress and strain to the vessel walls. In this study, super-elastic Nitinol wire was used to build stent samples usable to open femoral vessel. Ageing was performed at 500°C for different periods of time to determin...
