Naso-Duodenum (ND) or Naso-Jejunal (NJ) Tubes
Like NG tubes, ND/NJ tubes go through the nose and down the esophagus, but instead of going directly to the stomach, they end up in the small intestine.
The duodenum is the first part of the small intestine and the jejunum is a part of the small intestine just beyond that. You may hear your doctor use the term “pre-pyloric,” or “post pyloric” when talking about tubes. Anything that goes directly into the stomach is considered “pre-pyloric.” If a tube goes into your bowels, like a ND or NJ tube, it’s called “post pyloric.”
Tubes that must pass through the stomach and into the small intestine require a trained clinician to place it and shouldn’t be replaced at home if it’s significantly dislodged. In many hospitals and clinics, these tubes can still be placed at your bedside (meaning you don’t have to go to an operating room) if the clinician uses a visualization assistance, like a x-ray or CORTRAK* to ensure the tube ends up where it’s supposed to. You may be taken to an imaging room where your clinician can use special instruments, like fluoroscopy (x-ray) and/or an endoscope (small tube with a camera on the end, used to see inside your body) to place the tube as well as to confirm it’s reached the part of your body that it is supposed to.
Like NG tubes, ND/NJ tubes are typically used on a short-term basis for no longer than four to six weeks, however your doctor may choose to use these types of tubes for longer.
