Biliary Stents

Biliary Stentsaretubes whichare inserted into the common bile duct of the liver in situations when the duct has become blocked. After surgery, the stent is inserted to unblock the duct and to ensure that it remains operative and inflated.

The Biliary Stent is made of inert materials like metal or plastic, which are not likely to provoke an immune response. It plays a vital role in the health of the liver.

The liver is an important organ in the process of digestion by producing bile that helps in the breakdown of fats. The Bile drains from the liver to the common bile duct and this duct empties into the portion of the bowel which receives partially digested food from the stomach. Normal liver function and digestion is prevented by blockage of the common bile duct.

The typical cause of non-malignant duct blockage is an injury to the duct during surgery for gall bladder removal. Typical bile duct blockage can be caused also by gallstones, traumatic injury to the abdomen or inflammation of the pancreas, which is an organ located under the liver.

Bile ducts can become inflamed in a condition called as Primary Sclerosing Cholangitis. All such conditions may need treatment, with biliary stents to correct the problem of duct blockage. Biliary stents can be sourced online from biliary stent manufacturers.

As part of biliary stenting surgical procedure, a catheter is inserted first into the blocked bile duct to permit duct to drain. The next step is to insert a stent. There are two methods by which stent can be placed: ERCP (Endoscopic Retrograde CholangioPancreatography) and PTC (Percutaneous Transhepatic Cholangiography (PTC).

ERCP includes the use of a hollow, lighted tube called an endoscope. This tube is inserted into the mouth of a patient, through the oesophagus and stomach to the point at which the common bile duct empties into the small intestine. After the endoscope is put in place, a second tube called as a cannula is inserted. Through the cannula, a coloured dye is injected into the bile duct.

As a next step, the doctor takes X-rays of the abdomen. The dye enhances the contrast of the X-rays, such that bile duct blockages can be easily identified. In case, a biliary stent is required, it is inserted via the catheter and placed at the spot of blockage which is pointed out by high contrast X-rays.

Sometimes, ERCP fails to identify sites of bile duct blockages. In such situations, PTC might be used to identify a blocked bile duct. As per this procedure, contrast dye is injected via the skin and X-rays are taken. When the stent is required, the doctor inserts a hollow needle into the skin, through which stent is inserted into the blocked duct.

Such biliary stenting procedures can be used successfully to treat the majority of cases of non-malignant bile duct blockages. After undergoing this procedure, patients need to stay in the hospital for a few hours or maybe overnight. The duration of stay depends on the general health of patients and the presence of any risks like jaundice or infection. Some of the possible complications include infection, bile duct inflammation and gallbladder inflammation.

Another complication includes blocking of the stent over time. Some of the symptoms of this condition are: abdominal pain on the upper right side, Biliary Colic-spasmodic upper abdominal pain, pain under the right shoulder blade, fever, nausea and vomiting, itchy or yellow skin and flatulence.

These are some of the top facts about Biliary Stenting.
