Balloon G-J Tube

Also known as: balloon gastrostomy-jejunostomy tube, low-profile balloon jejunostomy tube, GJ tube

What is balloon G-J tube?

A balloon G-J tube is used to feed a child if he or she is unable to take food by mouth. The tube actually has two ends, one that is in stomach, and second that ends in the small intestines. The tube can be used for both feedings and for venting air from the stomach or intestines. The tube can also be used to administer medications.

When a Low-Profile Balloon J Tube is used, the tube is close to the belly and does not hang out, the balloon is filled with water to keep it in place in the stomach.

What happens during the procedure?

The tube is placed (or replaced) using X-ray to guide it into position. A balloon is inflated around the tube to prevent it from falling out. A disc is also placed around the outside of the tube to serve the same purpose. The tube is then used to help the child during feedings and for other purposes.

Is any special preparation needed?

The child will need to avoid food and drink for a set period of time before the procedure.

What are the risk factors?

Bleeding, infection, tearing of the bowels or equipment failure are possible complications of balloon G-J tube.
