Special Considerations

ERCP (endoscopic retrograde cholangiopancreatography) is an invasive procedure performed by gastroenterologists to visualize the bile ducts and to remove obstructing stones. If a diagnostic ERCP cannot be performed, or has failed in the past, PTCA may be performed. MRCP (magnetic resonance cholangiopancreatography) is a newer, noninvasive imaging method, based on MRI, which provides similar views of the biliary ducts in multiple planes.
