What are G and GJ tubes?
Gastrostomy tubes (G tubes) and gastrojejunostomy tubes (GJ tubes) are feeding devices. A G tube gives liquid nutrition, medication and other fluids directly into the stomach. A GJ tube gives liquid nutrition, medication and other fluids directly into the small intestine (the jejunum). Both G tubes and GJ tubes are placed in a surgical opening in your child's tummy (abdomen) called the stoma. The tunnel from the outside of the body into the stomach is called the tract.
