ERCP
An endoscopic retrograde cholangiopancreatography (ERCP) is an examination of the gallbladder and pancreas and the ducts (tubes) that drain those organs and the liver. Using an x-ray machine, medical dye and ERCP scope (flexible tube), the endoscopist will examine these organs, looking for blockages, irregularity in the tissue or flow of bile/pancreatic fluid, spasm of the ducts, stones or tumors. The procedure takes approximately one hour.
Reasons for an ERCP include evaluations of:
Preparation: You will be asked not to eat or drink anything 6-8 hours before the test. Ask your doctor about medications. Arrange for a responsible person to escort you safely home after the examination. Due to residue of sedation medications, do not operate heavy machinery, make major decisions or drink alcohol for 24 hours.
- Pancreatitis (inflammation of the pancreas)
- Possible pancreatic malignancy
- Abnormal or unclear findings in the biliary system on a CT exam
- Chronic or acute abdominal pain when biliary disease is suspected
- Jaundice (yellow skin) when bile duct disease is suspected
- Patients who undergo laparoscopic gallbladder removal to detect gallstones which might ne blocking the ducts
- Also to remove gallstones that are not passing through the ducts into the small intestine. Some stones are too large and get stuck.
Procedure: You will gargle with a medication to numb your throat (or a numbing spray). You will remove your dentures and lie on your side or stomach on an x-ray table. A plastic mouth guard will be placed between your teeth to prevent damage to your teeth and to the scope. Medications will be administered through the intravenous line. Most people sleep during the examination.
The ERCP scope, a flexible tube the size of an idex finger, has a lens and light source that allows the endoscopist to look at magnified images on a computer monitor. The endoscopist will introduce the scope through your mouth using air to open the esophagus, stomach, and intestine. When the scope reaches your duodenum, the endoscopist will locate the ampulla (the opening into the ducts that drain the biliary system) and place a smaller cannula tube to inject contrast dye to see the tissues through x-ray.
Recovery: You may feel a bit groggy, experience a feeling of bloating or gas cramps from the air and have a mild sore throat. Let the doctor know if you are uncomfortable. Rest during the day and eat a regular diet unless your doctor prescribes otherwise.
Report these symptoms immediately to your doctor:
