What procedure is involved in endoscopic retrograde cholangiopancreatography?
Endoscopic retrograde cholangiopancreatography (ERCP) involves inserting an endoscope through the mouth, down the esophagus, into the stomach, and then into the duodenum. From there, a catheter is used to inject contrast dye into the bile and pancreatic ducts, and X-ray images are taken to diagnose and treat conditions such as gallstones, blockages, or tumors. Therapeutic interventions such as stone removal or stent placement can also be performed during the procedure.
