During an ERCP procedure, contrast material is injected into which duct?

• A. Common bile duct
• B. Pancreatic duct
• C. Hepatic duct
• D. Cystic duct

Answer: (A)

During an Endoscopic Retrograde Cholangiopancreatography (ERCP) procedure, contrast material is specifically injected into the common bile duct. This duct is responsible for draining bile from the liver and gallbladder into the duodenum. The goal of administering contrast into this duct is to visualize it along with the biliary tree using fluoroscopy. By injecting contrast into the common bile duct, healthcare professionals can diagnose blockages, stones, or other abnormalities within the biliary system.

The procedure is essential because it allows for both diagnostic imaging and therapeutic interventions. For instance, if any blockages are found, they can often be cleared during the same procedure. Understanding the function and location of the common bile duct is crucial for those involved in radiography and gastroenterology.
