Many times it is found in the human body that fluid like bile which is very important for digestion meets with a problem of getting obstructed due to narrow space. This phenomenon can be found in cases like unresectable pancreatic cancer, jaundice etc. A biliary stent which is also known as the bile duct stent, is a thin hollow tube which is placed into the bile duct and holds the duct open that is blocked or partly blocked and is very necessary for the cases mentioned above for reducing problems in digestion and improve overall quality of life in these patients.
How it works?
There are two processes for putting in the biliary stents. First one is using the ERCP method or Endoscopic Retrograde Cholangio-Pancreatography which uses a tube with a camera on the end which is passed down the throat and the other one is using the PTC method or Percutaneous Transhepatic Cholangiogram method where stent is passed through the tummy wall and the liver into the bile duct using a thin needle. In both cases sedatives are very much needed and the stent is put using a small wire and when it is in the right place the wire is removed. Then the biliary stents expand and start performing it’s job.
Types of stent and it’s supply
The biliary stents can be of two types – metal and plastic. Plastic stents are often used in the short term, such as before surgery to remove pancreatic cancer, or during tests to see if one can have surgery and usually replaced every three or four months. On the other hand, metal stents are wider than plastic stents and can expand and don’t get blocked easily. They last longer than plastic stents and there is less chance of infection. But both these stents are useful and are in great demand. Considering all the facts and requirements regarding the biliary stents, several stents making companies have stepped forward providing best support in the medical history. Various lengths and several characteristics have been imposed into the stents to meet various needs in the medical urgency. The biliary stent suppliers can easily be found over the internet with their list of products and services with the exact budget definition.
Factors to consider
The average duration of the stent in the body is about 12 months but studies recommend to replace it after every 3 to 6 months. Patients with forgotten biliary stents are inevitably treated with surgical intervention. But consulting with a registered doctor for which type or what length of biliary stents are needed is a must do for the patients.
Thus choosing the best possible option to have the biliary stent put in one’s body needs some serious cares from both the patients and their concerned doctors and choosing the biliary stents suppliers is also an important job in terms of both the materials and their longevity and their budget altogether. Thus surveying and gaining knowledge over the whole process is equally important.
