University of Minnesota Health physicians are among national leaders in the number endoscopic retrograde cholangiopancreatograms (ERCPs) we perform annually. An ERCP combines the use of a flexible, lighted scope with X-ray images to examine the tubes that drain your liver, gallbladder and pancreas. Our endoscopy experts work with a team of radiologists and surgeons to determine the best course of treatment for you. At our new endoscopy unit we perform both routine and advanced procedures, offering the latest instruments with high-resolution imaging capabilities.
