Tests and Procedures

Overview. ERCP is a procedure that examines the ducts that drain the liver, gallbladder and pancreas. The test combines the use of a flexible, lighted scope (endoscope) with X-ray pictures. It is used to provide important information that cannot typically be obtained by other diagnostic examinations, such as an abdominal ultrasound, CT scan or MRI.
