Endoscopic retrograde cholangiopancreatography (ERCP); with endoscopic retrograde insertion of tube or stent into bile or pancreatic duct

Endoscopic retrograde cholangiopancreatography (ERCP) is a specialized medical procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions affecting the bile and pancreatic ducts. This procedure is particularly useful in cases where there is a blockage or narrowing (stenosis) in these ducts. During ERCP, a flexible tube known as an endoscope is inserted through the patient's mouth, passing through the esophagus and stomach, and into the duodenum, which is the first part of the small intestine. The procedure specifically targets the Ampulla of Vater, the anatomical site where the pancreatic duct and the common bile duct converge. Once the endoscope reaches this location, a smaller catheter is introduced through the endoscope to access the ducts. The Ampulla of Vater is cannulated, allowing for the injection of contrast dye into the bile and pancreatic ducts. This contrast dye is crucial as it enables visualization of the ducts on x-ray images, helping to identify any obstructions, stones, or other abnormalities. If a stricture is detected, the catheter can be advanced over a guidewire into the affected duct. Additional contrast dye may be injected to enhance the imaging of the stricture. To alleviate the blockage and facilitate the drainage of bile or pancreatic secretions, a plastic tube or stent is then inserted into the narrowed area. This intervention not only aids in diagnosis but also provides therapeutic relief for the patient.
