A cholecystostomy tube is a small drainage catheter placed directly into the gallbladder through the skin. It drains excess bile and infected fluid when the gallbladder is swollen, blocked, or infected, relieving pressure and pain without requiring surgery. The procedure is most often used for people with acute gallbladder inflammation (cholecystitis) who are too sick to safely undergo gallbladder removal.
Why a Cholecystostomy Tube Is Placed
The standard treatment for an inflamed gallbladder is surgery to remove it entirely. But not everyone can tolerate that operation. A cholecystostomy tube becomes the alternative when surgery carries too much risk.
The most common reasons for placing one include:
- High surgical risk: Patients with multiple serious health conditions, particularly those with high anesthesia risk scores, may not safely tolerate general anesthesia and surgery.
- Delayed presentation: When someone arrives more than a week after symptoms began, the inflammation may be too severe for safe surgery. The tube stabilizes things first.
- Failed antibiotic treatment: If antibiotics alone don’t control the infection and the patient is deteriorating, the tube drains the source of sepsis directly.
- Bridge to surgery: For patients too acutely ill for an emergency operation but who might tolerate a planned procedure later, the tube buys time. Surgeons typically schedule gallbladder removal 8 to 13 weeks after tube placement.
- Definitive treatment: In patients with irreversible health conditions that permanently rule out surgery, the tube itself may be the final treatment.
During the COVID-19 pandemic, cholecystostomy tubes also saw wider use as hospitals favored less invasive procedures to reduce virus transmission and preserve surgical resources.
How the Tube Is Placed
Placement is a minimally invasive procedure, usually performed by an interventional radiologist rather than a surgeon. The most common approach uses ultrasound guidance, which gives the doctor a real-time view of the gallbladder, surrounding organs, and blood vessels. Ultrasound is portable, so the procedure can even be done at the bedside in an intensive care unit if the patient is too unstable to move.
In the ideal setup, the patient goes to a procedure suite where both ultrasound and fluoroscopy (a type of live X-ray) are available. The doctor numbs the skin with local anesthetic, then uses one of two techniques to access the gallbladder: either a multi-step approach using a thin guidewire or a single-step method with a pointed catheter. Once the needle reaches the gallbladder, a small amount of contrast dye is injected to confirm correct positioning without over-expanding the gallbladder. Then the drainage catheter is secured in place. If ultrasound isn’t feasible due to body size or anatomy, CT-guided placement works as an alternative.
The entire procedure is considered minor. Most patients are awake with sedation rather than under general anesthesia, which is precisely the point for people who can’t tolerate a full operation.
What Drainage Looks Like Day to Day
The tube connects to an external drainage bag that collects bile and fluid from the gallbladder. Normal bile is yellow to greenish-yellow. Some patients occasionally see clear, colorless fluid, which can alternate with normal-colored bile throughout the day. Daily drainage volume is typically modest, often under 60 milliliters (about a quarter cup).
Changes in the color, consistency, or volume of drainage can signal problems. Bloody output, a sudden stop in drainage, or a dramatic increase in volume are all worth reporting to your care team promptly.
Living With a Cholecystostomy Tube
Caring for the tube at home centers on keeping it clean, secure, and functioning. The insertion site needs to stay dry and covered with a clean dressing. You’ll be shown how to empty the drainage bag and how to flush the tube with small amounts of saline to prevent it from clogging. Keeping the bag below the level of your gallbladder helps drainage flow properly by gravity.
Physical activity is generally limited while the tube is in place. Sudden movements, bending, or lifting can pull on the catheter and risk dislodging it. Securing the tube to your skin with tape or a stabilization device reduces this risk. Showering is typically possible with precautions to keep the site dry (waterproof dressings or coverings), but submerging in a bath, pool, or hot tub is usually off-limits.
Possible Complications
Cholecystostomy tubes have a strong safety profile overall, but complications do occur. Reported rates vary widely, from under 3% to as high as 69% depending on how broadly complications are defined and how sick the patient population is.
Tube dislodgment is by far the most common problem, accounting for more than half of all complications in some reports. This can happen during sleep, while moving in bed, or simply from the tube gradually working its way out. A dislodged tube may need to be replaced quickly to prevent the drainage tract from closing.
Bile leakage is the next most frequent issue. If bile leaks into the abdominal cavity rather than draining through the tube, it can cause significant pain and inflammation. Bleeding, tube blockage, infection at the insertion site, and, rarely, accidental puncture of a nearby organ have also been reported but are uncommon.
When and How the Tube Comes Out
Removal depends on whether surgery is planned afterward. For patients who will eventually have their gallbladder removed, the tube typically stays in for 8 to 13 weeks before the operation. This waiting period lets inflammation settle and the patient recover enough to tolerate surgery.
Before removal, doctors usually perform a clamping trial: the tube is clamped shut for a period to see if the patient tolerates having drainage stopped. If there’s no return of pain, fever, or other symptoms, that’s a good sign the gallbladder is draining on its own through its natural duct. Research in JAMA Surgery found that a clamping trial was actually a better predictor of safe removal than a tube cholangiogram (an X-ray test that checks whether the bile duct is open).
Removing the tube before gallbladder surgery is associated with fewer tube-related complications during the waiting period, though it does slightly increase the chance of needing an emergency operation if symptoms return. For patients where the tube is the permanent treatment, it may be left in long-term with periodic exchanges to keep it functioning.
