Gastro-Jejunal (GJ) Tube
GJ tubes are a long-term option that combines a G tube with a J tube for more flexibility based on a person’s needs.
A GJ tube goes through the abdomen and ends up in two different places: the stomach for medicine and ventilation, and the small intestine (jejunum) for feeding. Like G and J tubes, GJ tubes use a water-filled balloon to help the tube stay put in the stomach.
Because it leads to multiple places, a GJ tube has multiple ports on the outside:
- One for the stomach [to administer medication or to vent (venting helps get rid of extra air or food)]
- One for the small intestine (to feed)
- One for the balloon (to add or take away water to help prevent dislodgement)
GJ tubes can serve as either a regular standard- length tube (“dangler”) or a low-profile, button tube and like J tubes, GJ tubes require a surgical procedure for placement and cannot be replaced at home.
What Does a GJ-Tube Look Like?
MIC-KEY* GJ Tube
This low-profile tube, sometimes called a “button,” uses an extension set that can be detached when not in use that allows it to be easily hidden under clothing.
MIC* GJ Tube
This is a standard-length tube, sometimes called a “dangler.”
MIC-KEY* Continuous Extension Set
The extension set attaches to any MIC-KEY* feeding tube when nutrition, fluids, or medication needs to be given. Continuous sets are used when feeding small amounts constantly throughout the day (or night) without interruption.
