What is a biliary stent?
Biliary stent is a tube that is inserted into the normal bile ducts of the liver in cases where the pipeline is blocked. The stent is inserted after the operation to unlock the pipe and ensure that it remains inflated and functional. Biliary stent is made of inert substances such as plastic or metal that probably do not cause an immune response.
liver play an important role in digestion of bile production, which is essential for breaking fat. Bile drains from the liver to conventional bile ducts and this pipe flows into a part of the intestine, which receives partially fissioned food from the stomach. Blocking conventional bile ducts prevents normal liver function and affects digestion.
The most common cause of non -nuggeting bile ducts is the damage to the pipeline during the gallbladder removal operation. Common blocking of bile ducts can also be caused by traumatic damage to the abdomen, bile stones or inflammation of the abdominal, located under the liver.Samotal bile ducts can also be inflamed, in a state called primary sclerotizingCholangitis. All these conditions may require a biliary stent treatment to repair the problem of pipe blocking. Biliary stent is also inserted. There are two different methods that can be placed with stent: endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous transhepatic cholangiography (PTC).
ERCP includes the use of an illuminated, hollow tube called an endoscope. The tube is brought to the patient's mouth, through the esophagus and stomach to the point where the common bile canal flows into the small intestine. Once the endoscope is in place, the second tube called the cannula is inserted. The cannula is used to injure the colored dye into the DUCT bile.
Furthermore, X -rays of the abdomen are collected. The dye improves the contrast of X -rays, so it is easy to locate the bile ducts blocking. If a biliary stent is needed, it is inserted via the catheter and placed on the location of the blockade as indicated on the X-ray rays with youa plinth contrast.
In some cases, ERCP is unable to find bile ducts. If this happens, PTC can be used to search for blocked bile ducts. In this procedure, the contrasting dye is injected through the skin and X -rays are removed. If there is a need for a stent, a hollow needle is inserted into the skin and the stent is inserted into a blocked pipe with a needle.
Most cases of non -signic blocking of bile ducts can be successfully treated with one of these billiard stenting procedures. After the procedure, patients can only stay in the hospital for only a few hours or overnight. The length of stay depends on the overall physical health of the patient and the presence of any risk factor for complications such as infection or jaundice. Possible complications include gallbladder inflammation, bile inflammation and infection.
