Pancreatic stenting
Pancreatic stenting involves inserting a small tube (stent) into the pancreatic duct to address various conditions, including pancreatic duct obstruction, leaks, and to prevent post-ERCP pancreatitis.
Here's a more detailed explanation:
What it is:
Pancreatic stenting is a procedure where a stent, a small tube, is placed into the pancreatic duct (the tube that carries pancreatic juices) to help with drainage or to keep the duct open.
Why it's done:
- Treating pancreatic duct obstruction: Stents can help bypass blockages in the pancreatic duct, relieving pressure and pain.
- Treating pancreatic duct leaks: Stents can help seal leaks in the pancreatic duct, preventing complications.
- Preventing post-ERCP pancreatitis: Stents can be placed after an ERCP (Endoscopic Retrograde Cholangiopancreatography) procedure to reduce the risk of pancreatitis.
- Other uses: Stents can also be used to treat pancreatic fistulas, complications of acute pancreatitis, and other pancreatic disorders.
Types of stents:
- Plastic stents: These are commonly used for temporary drainage or to prevent post-ERCP pancreatitis.
- Metal stents: These are used for longer-term drainage or when plastic stents are not suitable.
How it's done:
- Endoscopic retrograde cholangiopancreatography (ERCP): Stents are typically placed during an ERCP procedure, where a flexible tube with a camera is inserted into the digestive tract to access the pancreatic duct.
Potential complications:
- Pancreatitis: Although stents are used to prevent pancreatitis, there is a risk of pancreatitis during or after the procedure.
- Stent migration: The stent can sometimes migrate out of place.
- Stent occlusion: The stent can become blocked, requiring removal or replacement.
- Infection: There is a risk of infection, although it is rare.
When to consider pancreatic stenting:
- Chronic pancreatitis: Stents can help relieve pain and improve drainage in patients with chronic pancreatitis.
- Pancreatic duct strictures: Stents can help bypass or dilate strictures (narrowing) in the pancreatic duct.
- Pancreatic fistulas: Stents can help drain and seal pancreatic fistulas (leaks).
- Post-ERCP pancreatitis: Stents can be used to prevent pancreatitis after an ERCP procedure.
