Definition. Endoscopic retrograde cholangiopancreatography (ERCP) is a technique in which a hollow tube called an endoscope is passed through the mouth and stomach to the duodenum (the first part of the small intestine). This procedure was developed to examine abnormalities of the bile ducts, pancreas, and gallbladder.
ERCP is usually performed in a hospital endoscopy unit or ambulatory surgery center. It is an outpatient procedure, so patients do not have to stay overnight in the hospital. How does ERCP compare with other techniques used to image the pancreas?
