Bile is made in the liver and stored in the gallbladder. It helps digest food. Bile normally passes out of the liver through a series of tubes (ducts). Bile can back up into the liver if a duct becomes blocked. It can also back up if a hole or tear forms in a duct. Biliary drainage is a procedure to drain bile from the liver. The procedure is done by a specially trained doctor called an interventional radiologist.
Follow any instructions you are given on how to get ready. These include:
Follow any directions you’re given for not eating or drinking before the procedure.
Tell the technologist if you are or could be pregnant,or if you are breastfeeding.
Tell the technologist if you are allergic to X-ray dye (contrast medium) or other medicines.
Be sure your doctor knows about all medicines you take. You may be told to stop taking some or all of them before the test. This includes:
All prescription medicines
Over-the-counter medicines that don't need a prescription
Any street drugs you may use
Herbs, vitamins, kelp, seaweed, cough syrups, and other supplements
You will change into a hospital gown and lie on an X-ray table.
An IV (intravenous) line will be put into a vein. This is to give you fluids and medicines. You may be given medicine to help you relax and make you feel sleepy.
The skin on your stomach is cleaned. Medicine is put on the skin to numb it.
A needle is put into the liver. Contrast medium is injected into the ducts. This helps the duct system show clearly on X-rays.
A thin, flexible tube (catheter) is put in and moved into the liver. The radiologist uses X-ray or ultrasound pictures as a guide. He or she moves the catheter into the duct that needs to be drained.
Bile drains through the catheter out of your body. A bag is attached to the end of the catheter to collect the bile as it drains.
The catheter may be temporarily sutured or taped to your skin to keep it secure and prevent it from moving.
The radiologist may be able to use the catheter to clear the blockage during the procedure. In this case, a mesh tube (stent) may then be put in the duct to help keep it open. This allows the catheter to be taken out, usually at a later time.
A slight fever (1°F above your normal temperature) is normal for the first 24 hours after the procedure. If the fever lasts longer than 24 hours do what your health care provider
You will likely stay in the hospital overnight or longer.
Care for the catheter and drainage site as directed.
Talk with your health care provider about how long the catheter will need to stay in place.
Infection inside your body or at the insertion site
Bleeding at the insertion site
Leakage of bile into the abdomen
Liver injury and bleeding inside the liver. You may need a blood transfusion for this.
Problems because of contrast medium. These include allergic reaction or kidney damage.
Exposure to generally safe and low levels of X-ray radiation. This exposure is felt to be very low and usually this risk is far outweighed by the benefits of the study.
