Endoscopic Retrograde Cholangiopancreatography (ERCP)

This procedure is performed for both diagnostic and therapeutic purposes and is generally preferred for evaluating issues in the upper-to-mid gastrointestinal tract. ERCP plays a critical role in identifying and treating disorders associated with the gallbladder, biliary tract, and pancreas.

How is the ERCP Procedure Performed?

The ERCP procedure is conducted using a specialized duodenoscope (endoscope) combined with fluoroscopy (real-time X-ray imaging).

• Sedation and Access: The patient is typically placed under conscious sedation, and the endoscope is introduced orally.
• Cannulation: The scope is advanced through the upper digestive tract until it reaches the duodenum (specifically the major duodenal papilla).
• Contrast Injection: A catheter is then passed through the endoscope into the common bile duct and pancreatic duct to inject a radiopaque contrast medium.
• Fluoroscopic Visualization: This contrast medium delineates the anatomy of the biliary tree and pancreatic ducts, allowing the clinician to detect structural and luminal abnormalities under real-time fluoroscopic monitoring.

Clinical Indications and Therapeutic Interventions

ERCP is widely utilized in the management of conditions such as choledocholithiasis (gallstones in the bile duct), biliary strictures, pancreatitis, and pancreatic malignancies.

Beyond its diagnostic capabilities, it serves as a platform for immediate therapeutic intervention:

• Biliary Stone Extraction: When gallstones are detected within the ducts, various techniques—such as endoscopic sphincterotomy followed by basket or balloon extraction—can be performed to clear the obstruction.
• Stricture Management and Stenting: In cases of benign or malignant strictures, mechanical dilation can be performed, and plastic or self-expanding metal stents can be deployed to restore patency and bile flow.

Consequently, ERCP is a vital medical technique that uniquely integrates high-precision diagnostics with immediate, minimally invasive therapeutic solutions.
