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
You will need to fast at least 4 hours before the test and sign a consent form. Remove all jewelry so that it will not interfere with the x-ray.
Because of the intravenous sedation, you may not feel any discomfort, and may have no memory of the test. There may be some gagging as the tube is passed down the esophagus. As the scope is positioned, there will be some stretching of the stomach and duodenum. Occasionally, stretching of the ducts can be felt.
Air, used to inflate the stomach and bowel, can cause some bloating or gas. After the procedure, you may have a sore throat for 3 to 4 days. Some people have a bad reaction to the dye or the drugs used to relax the duodenum, which can cause symptoms like nausea, hives, burning sensation, blurred vision, and urine retention.
The procedure is used to identify any problems of the pancreas or bile ducts that can cause abdominal pain (usually in the right upper or middle stomach area) and yellowing of the skin and eyes ( jaundice). These include:
ERCP is often performed after gallstones in the common duct are discovered during cholecystectomy.
A procedure called endoscopic sphincterotomy (ES) can be done at the same time as an ERCP.
The x-ray will show normal structures for the age of the patient.
Additional conditions under which the test may be performed:
Reactions to the anesthesia, dye, or drug used during this procedure may include
Risks related to the procedure include:
Long-term complications include:
