A biliary stent, also known as a bile duct stent, is a small tube-like device inserted into the bile duct to keep it open. The bile ducts are part of the digestive system and are responsible for carrying bile from the liver and gallbladder to the small intestine, where it helps with digestion.
Biliary stents are primarily used to treat obstructions or strictures (narrowing) within the bile ducts. These obstructions can occur due to various reasons, including:
Gallstones: Stones in the gallbladder or bile ducts can sometimes block the flow of bile.
Biliary Strictures: Narrowing of the bile ducts can occur due to inflammation, scarring, or other factors.
Bile Duct Tumors: Tumors within or adjacent to the bile ducts can obstruct bile flow.
Post-surgical Complications: Biliary stents may be used after certain surgeries involving the bile ducts to prevent narrowing or strictures from developing.
The insertion of a biliary stent helps to alleviate symptoms associated with bile duct obstruction, such as jaundice (yellowing of the skin and eyes), abdominal pain, nausea, and vomiting. By keeping the bile duct open, the stent allows bile to flow freely, which can relieve symptoms and improve liver function.
Biliary stents can be temporary or permanent, depending on the underlying condition being treated and the patient's response to treatment. Temporary stents may be removed once the underlying issue, such as a bile duct stone or tumor, has been addressed or resolved. Permanent stents may be necessary in cases where the underlying condition cannot be fully corrected or when the patient's health status precludes further interventions.
