Endoscopic Retrograde Cholangiopancreatography

UW Health offers endoscopic retrograde cholangiopancreatography (ERCP), a minimally invasive technique for diagnosing and treating diseases of the pancreas, gallbladder, liver and bile ducts.
During ERCP, a flexible tube (an endoscope) is passed through the mouth, esophagus and stomach into the first part of the small intestine. Dye is injected through the tube into the pancreatic and bile ducts, and an X-ray is taken. Instruments can also be inserted through the scope to remove stones, insert drains, remove tissue samples or perform other treatments.
ERCP is usually performed in an outpatient setting under mild sedation.
