Two approaches in the treatment of malignant obstructive jaundice using nitinol stents

Biliary stents in malignant obstructive jaundice due to pancreatic carcinoma: a cost- effectiveness analysis

Health technology The use of two methods for endoscopic placement of biliary stents in patients with pancreatic carcinoma. The methods examined were plastic (polyethylene) stents and metallic stents. Plastic stents were widely used due to their ease of insertion and low costs. However, their major disadvantage was their tendency to clog because of bacterial biofilm formation and biliary sludge....

Percutaneous stent placement for the treatment of malignant biliary obstruction: nitinol versus elgiloy stents

OBJECTIVE This study aimed to compare two self-expanding stents, a nitinol stent and an elgiloy stent, both placed percutaneously, in terms of their efficacy in palliating inoperable malignant biliary obstruction. MATERIALS AND METHODS We retrospectively investigated 99 patients with unresectable malignant biliary obstruction treated with percutaneous placement of a self-expanding metallic st...

Chemical etching of nitinol stents.

At present the main cause of death originates from cardiovascular diseases. Primarily the most frequent cause is vessel closing thus resulting in tissue damage. The stent can help to avoid this. It expands the narrowed vessel section and allows free blood flow. The good surface quality of stents is important. It also must have adequate mechanical characteristics or else it can be damaged which ...
