Endoscopy is a minimally invasive procedure that uses a flexible tube with a camera to view the digestive tract and pancreas, allowing for both diagnosis and treatment. Here is a breakdown of key ASGE recommendations for endoscopic therapy in CP:
- Endoscopic Therapy vs. Surgery for Pain Relief
CP can cause severe pain, often linked to a blocked pancreatic duct. ASGE suggests:
- Surgical Evaluation: Surgery should be considered first if viable.
- Endoscopic Approach: If surgery is not suitable or is not preferred, endoscopic therapy can be used to relieve pain by clearing ductal obstructions.
For You: If surgery is not an option or preferred, endoscopic therapy might offer pain relief by addressing ductal obstructions.
- Celiac Plexus Block for Pain Management
A celiac plexus block (CPB) targets specific nerves to ease pain, with two primary approaches:
- EUS-Guided Approach: ASGE recommends endoscopic ultrasound (EUS) over percutaneous (through the skin) methods for more precise, effective pain control.
For You: If pain remains despite standard methods, an EUS-guided celiac plexus block might provide significant relief.
- Managing Pancreatic Duct Stones
Pancreatic duct stones can block enzyme flow and worsen symptoms. ASGE guidelines advise different treatments based on stone characteristics:
- Large, Radiopaque Stones: For stones over 5 mm, endoscopic retrograde cholangiopancreatography (ERCP) with or without pancreatoscopy (a camera to enhance ERCP) or extracorporeal shock wave lithotripsy (ESWL) may be used.
- Smaller or Radiolucent Stones: Treated via ERCP with or without pancreatoscopy.
For You: If you have painful duct stones, your doctor will recommend a treatment based on stone type and size, often using endoscopic therapies like ERCP or ESWL to break up and remove stones.
- Treating Pancreatic Duct Strictures
Narrowed pancreatic ducts (strictures) can block enzymes, increasing pain and inflammation. ASGE suggests:
- Using a Plastic Stent: Single plastic stents are generally recommended for initial treatment.
- Avoiding Metal Stents: Fully covered self-expanding metal stents (FCSEMSs) are used only in refractory cases.
For You: If you have a duct stricture, endoscopic stenting may help keep the duct open, chosen based on severity.
- Managing Benign Biliary Strictures (BBSs)
Chronic Pancreatitis can lead to strictures in the bile duct, causing jaundice or liver issues. ASGE advises:
- Using Fully Covered Metal Stents: These are recommended over multiple plastic stents for treating biliary strictures.
For You: If CP has caused biliary strictures, an endoscopic stent using metal stents may provide better, longer-lasting results.
- Treating Symptomatic Pseudocysts or Walled-Off Necrosis
Fluid-filled sacs or dead tissue (pseudocysts or walled-off necrosis) can develop due to pancreatitis. They may cause discomfort, nausea, obstruction, infection, or even organ failure. ASGE advises:
- Endoscopic Drainage: Endoscopic drainage is preferred over surgery for symptomatic pseudocysts and walled-off necrosis.
For You: If these complications are causing issues, endoscopic drainage offers a minimally invasive option that avoids surgery.
