Which procedure is represented by the abbreviation ERCP?

• A. Endoscopy
• B. Esophagoscopy
• C. Endoscopic Retrograde Cholangiopancreatography
• D. Esophagogastroduodenoscopy

Answer: (C)

ERCP stands for Endoscopic Retrograde Cholangiopancreatography. This is a specialized endoscopic procedure that uses a scope passed to the duodenum to access the major papilla, then injects contrast into the bile ducts (cholangiography) and pancreatic ducts (pancreatography) in a retrograde fashion while taking X-ray images. It’s specifically designed to visualize and treat problems of the biliary and pancreatic ducts, such as stones, strictures, or leaks. This distinguishes it from general endoscopy or procedures that examine the esophagus, stomach, or duodenum without focusing on the ductal systems. It can also be therapeutic, enabling interventions like stone extraction or stent placement.
