An endoscopic retrograde cholangiopancreatogram (ERCP) is usually done by a gastroenterologist. This is a doctor who has special training in diseases of the digestive system. The doctor must be trained in endoscopy. A thin, flexible fiber-optic endoscope (scope) is used.
ERCP is used primarily to diagnose and treat conditions of the bile ducts and main pancreatic duct, including gallstones, inflammatory strictures (scars), leaks (from trauma and surgery), and cancer.
