Palliative care: Stents help patients with advanced esophageal cancer by relieving symptoms and improving the quality of life. Alternative to surgery: For older and less healthy patients, an esophageal stent is a viable alternative to surgery, Cons of Esophageal Stent. There are also several potential drawbacks to an esophageal stent procedure:
This leads to varices in the esophagus and stomach, which can bleed; B) a needle has been introduced (via the jugular vein) and is passing from the hepatic vein into the portal vein; c) the tract is dilated with a balloon; D) after placement of a stent, portal pressure is normalized and the coronary and umbilical veins no longer fill.
Endoscopic stenting is a medical procedure by which a stent, a hollow device designed to prevent constriction or collapse of a tubular organ, is inserted by endoscopy.They are usually inserted when a disease process has led to narrowing or obstruction of the organ in question, such as the esophagus or the colon.
A plastic self-expanding stent (Polyflex, Boston Scientific) has also been developed for similar applications. It confers an additional advantage as it is designed to be removable, and may have a less traumatic insertion than metal stents. The Polyflex stent has shown benefit in palliation of esophageal malignancies. [7]
Stenting is performed through a procedure called percutaneous coronary intervention (PCI), where the cardiologist uses angiography and intravascular ultrasound to assess the blockage in the artery and determine the appropriate size and type of stent. The procedure is typically done in a catheterization clinic, and patients may need to stay ...

A bare-metal stent is a stent made of thin, uncoated (bare) metal wire that has been formed into a mesh-like tube. The first stents licensed for use in cardiac arteries were bare metal – often 316L stainless steel. More recent "second generation" bare-metal stents have been made of cobalt chromium alloy. [1]
