Nasojejunal Tube (NJ Tube)

What is a nasojejunal (NJ) tube?

A nasojejunal (NJ) tube is a small tube that is passed through the nose and into the small bowel to feed children who cannot get enough nutrients by eating.

How is a nasojejunal tube placed?

After numbing gel is placed on the nose a small tube will be guided down the nose and into the jejunum (small bowel) using fluoroscopic (X-ray) guidance. To help visualize the stomach and small bowel, a small amount of contrast (X-ray dye) will be injected through the tube. Once positioned, the tube will be secured to the cheek with adhesive tape.

Is the procedure painful?

There can be some discomfort when the tube is guided down through the nose. Your child may be sedated, depending on your child’s age and medical history.

What risks are associated with the procedure?

The procedure is considered very low risk but the potential complications include:

  • Nosebleed
  • Injury to the esophagus, stomach and/or small bowel
