The gallbladder is a small sac-like structure under the liver. It stores bile that is secreted into the intestines to help digest fats. Over time, the gallbladder can become obstructed or infected. Treatment usually includes antibiotics and, if necessary, surgical removal. However, sometimes surgery is not an option because the patient is too sick or for other reasons. In these cases, an interventional radiologist will perform a cholecystostomy, a procedure in which a drainage catheter is placed in the gallbladder. This catheter keeps the gallbladder from getting too swollen, until the child is well enough for surgery.
Using ultrasound and live X-ray (fluoroscopy) for guidance, the radiologist will insert a small needle through the skin and into the gallbladder, and then place a tiny catheter into the gallbladder. The catheter will be connected to a drainage bag or bulb, which will be located outside of the body in the right upper abdomen. We will place gauze and clear a bandage over the site. The bandage must remain dry and in place at all times. In addition, the catheter will be secured with a locking device (StatLock®), which must not be removed. The amount of time that the catheter and drainage bag will be in place varies from several days to weeks or longer.
Your child will be protected by an X-ray shield during the procedure.
Patients receive either IV sedation or general anesthesia and are asleep for this procedure.
The procedure is considered low-risk. However, potential complications include:
Some children feel pain or discomfort at the needle-insertion site, usually in the first day or two after the procedure. You may give over-the counter pain medication if the pain lingers on.
You may sponge bathe your child, but keep the needle-insertion site dry.
Your child will need to avoid activities that may result in a pull to the catheter.
