How to Prepare for a Biliary Intervention

Patients are routinely given antibiotics prior to this procedure.

You may have blood drawn prior to your procedure.

Prior to your procedure, your blood may be tested to determine how well your liver and kidneys are functioning and whether your blood clots normally.

Tell your doctor all medications that you are taking, including herbal supplements, and if you have any allergies, especially to local anesthetic medications, general anesthesia or to contrast materials (also known as "dye" or "X-ray dye"). Your doctor may tell you to stop taking aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs) or a blood thinner for a specified period of time before your procedure.

Also inform your doctor about recent illnesses or other medical conditions.

Women should always inform their doctor or X-ray technologist if there is any possibility that they are pregnant. Radiation is not good for the fetus. If an X-ray is necessary, precautions will be taken to minimize radiation exposure to the baby.

You will receive specific instructions on how to prepare, including any changes that need to be made to your regular medication schedule.

You may not eat for eight hours before your exam. You may have clear liquids up until four hours before your procedure.

You may be asked to remove some or all of your clothes and to wear a gown during the exam. You may also be asked to remove jewelry, eye glasses and any metal objects or clothing that might interfere with the x-ray images.

You should plan to have a relative or friend drive you home after your procedure.

Some biliary interventions require an overnight stay at the hospital.
