Stenting is the most common technique used in endoscopy. The treatment for biliary obstruction in people with pancreatic cancer has been done by this product. So, if you are looking for the same for your clinic, then, you can get it from many good, endoscopy device companies.

Biliary stent for endoscopy can be found in two materials, plastic and then metal. Both products have their benefits and shortcomings. So, if you are a novice in this matter, then, here is the matter covered just to help you out.

Plastic stent

From the past couple of years, fixed-diameter plastic stents have been used to relieve jaundice and improve the overall quality of life in so many patients.

However, plastic stents tend to block after about three months because of usage because of their size and of the diameter of the working channel of the endoscope. This very thing encourages the growth of bacterial biofilm and accumulation of biliary sludge. Several modifications are attached with these issues, which consists of, large bore stents, that have not been displayed to increase patency, also, plastic stent usage in patients with longer life expectancies have the chances in resulting into recurrent jaundice and enhanced interventions with longer hospital stays.

Metal Stent

Metal stents are highly self-expandable, and this consists of post-expansion diameters ranging from 6 to 10 millimeters, which is three times longer that of plastic stents. These were specially developed to overcome such limitations. Larger diameters are capable of enhancing patency duration to six months or more and it also reduces the formation of biofilm.

However, metal stents have certain drawbacks. In so many studies it has been found out that, in the earlier days, bare metal stents were used, which merge into the wall of the bile duct and are nearly impossible to remove if they somehow become blocked.

The solution to this issue was to cover the devices and at first partially, just leaving only the ends uncovered and after that, fully, with silicone. This prevents the tissue implanting and any chances of stent-induced hyperplasia.

Selection of stent

The choice of stent depends on the patient prognosis and the apparent costs of metal stents with that the repeat endoscopic retrograde cholangiopancreatographies. Normally, plastic stents are very reasonable for patients, who are surviving less than three months and metal stents are more cost-effective for patients but they are always expected to live longer.

Studies point out that not all insurers reimburse enough to cover the institutional cost of metal stents. On the other hand, Plastic stents, which require periodic replacement for the prevention or treatment of blockage, are entirely reimbursable. You can get the same from many biliary stent manufacturers.

Neoadjuvant therapy and Stents
