Stenting in the biliary tract refers to the placement of a small tube (stent) within the bile ducts to keep them open and facilitate bile drainage. It is used to treat blockages or narrowing that prevent proper bile flow.
Some key points about biliary stenting:
- Bile ducts can become blocked due to gallstones, tumors, scarring, or injury. This can cause a backup of bile, leading to jaundice, infection, pancreatitis, and liver damage.
- A stent props open the bile duct to allow bile to drain from the liver, gallbladder, and pancreas into the small intestine. This helps relieve pressure and symptoms.
- Stents are placed during an endoscopic retrograde cholangiopancreatography (ERCP) procedure. A flexible camera is passed down the throat to access the bile ducts.
- Different types of biliary stents are used:
- Plastic stents are cheaper but may clog over time.
- Metal stents are more durable and remain open longer.
- Covered stents prevent tissue ingrowth.
- Stents provide short or long-term relief depending on the type. Plastic stents may need to be replaced every 3-6 months.
- Stenting helps avoid surgery and allows time for infections, strictures, or tumors to be further treated. Stents may be placed prior to surgery as well.
- Complications include migration of the stent, blockage, and rarely bile leaks. Stents may need adjustments or replacements.
So in summary, biliary stenting uses a small tube to keep bile ducts open and draining properly when a blockage or narrowing affects bile flow out of the liver. It provides a minimally invasive option to relieve symptoms.
