Endoscopic retrograde cholangiopancreatography (ERCP) is a procedure used to identify stones, tumors, or narrowing in the bile ducts. The procedure is done through an endoscope.

Endoscopic retrograde cholangiopancreatography; Papillotomy; Endoscopic sphincterotomy

An intravenous (IV) line is placed in your arm. You will lie on your stomach or on your left side for the test. Medicines to relax or sedate you will be given through the IV. Sometimes a spray to numb the throat is also used. A mouth guard will be placed in your mouth to protect your teeth. Dentures must be removed.

After the sedative takes effect, the endoscope is inserted through the mouth, and passed through the esophagus (food pipe) and stomach until it reaches the duodenum (the part of the small intestine that is closest to the stomach).

A catheter (thin tube) is passed through the endoscope and inserted into the tubes (ducts) that lead to the pancreas and gallbladder. A special dye is injected into these ducts, and x-rays are taken. This helps the doctor see stones, tumors, and any areas that have become narrowed.

Special instruments can be placed through the endoscope and into the ducts to

• Open the entry of the ducts into the bowel
• Stretch out narrow segments
• Remove or crush stones
• Take tissue samples
• Drain blocked areas
