A cholecystostomy tube is a thin, plastic tube (catheter) that's placed though the skin and into the gallbladder. It's also called a percutaneous cholecystostomy tube. It lets bile flow from a blocked gallbladder into a collection bag outside the body.
Bile is a fluid that the liver makes. It helps digest fats. When the gallbladder can't release bile, it can cause yellowing of the skin (jaundice) or an infection of the liver.
The tube is used to help treat sudden inflammation of the gallbladder (acute cholecystitis). It may also be used when removing the gallbladder (cholecystectomy) isn't an option.
Bile that collects in the bag may look bloody at first. It will soon change to its normal yellow-green color. About 2 to 4 cups of bile will collect in the bag each day. The amount should be about the same from day to day.
The tube will need to be changed every 6 to 8 weeks. How long the tube stays in depends on what caused the problem with your gallbladder.
