Who needs a biliary stent?

Here are some common reasons someone may need a biliary stent:

- Gallstone-related blockage - A gallstone may move into the common bile duct, blocking the flow of bile. A stent can be placed to hold the duct open.

- Tumor compression - Cancers of the pancreas, liver, or bile duct can compress and narrow the bile ducts. A stent can help keep the ducts open.

- Strictures - Scarring from surgery, gallstone disease, or chronic inflammation can cause abnormal narrowing (strictures). A stent helps widen the bile duct.

- Bile leaks - A leak in the bile ducts, often after gallbladder surgery, is repaired by placing a stent to divert bile flow and allow healing.

- Pancreatitis - A stent may be used short-term to improve bile drainage in acute or chronic pancreatitis.

- Pre-surgery - Stents are sometimes placed to improve bile flow before gallbladder or bile duct surgery.

- Post-surgery - After a procedure like gallstone removal or bile duct surgery, a stent secures drainage while healing occurs.

- Bile duct injury - Trauma or unintended damage to the ducts may require a stent while they mend.

- OTHER - Stents can also be used in rare situations like cholangitis, biliary sphincter dysfunction, or liver transplant.

In general, stents are used whenever something is obstructing or disrupting the normal flow of bile. The stent provides structural support to keep ducts open and draining properly.
