A Gastrojejunostomy (GJ) Tube is similar to a standard G-tube, but it is longer. Instead of stopping in the stomach, the tube passes through the stomach and extends deeper into the small intestine (the jejunum).
Common Indications for a GJ Tube
Your doctor may recommend a GJ tube instead of a G-tube if you:
- Have severe acid reflux or a high risk of inhaling (aspirating) stomach contents into your lungs.
- Suffer from gastroparesis, a condition where your stomach empties too slowly.
- Have a blockage in your stomach or the first part of your intestine.
What happens during the procedure?
The setup is nearly identical to a G-tube placement. However, once the needle reaches the stomach, the radiologist uses live X-ray video to expertly navigate a thin wire out of the bottom of the stomach and down into the small intestine. The soft feeding tube is then threaded over the wire, ensuring the nutrients bypass your stomach entirely.
Do I need to prepare?
Yes, fasting for 8 hours is required. You may also be given a special liquid to drink the night before to help outline your digestive tract on the X-rays.
How long does it take?
Because the tube must be carefully guided further into the digestive tract, this procedure takes slightly longer, usually 45 to 60 minutes.
Will it be painful?
With local numbing and conscious sedation, the procedure is not painful. You will likely feel pressure and a sensation of fullness in your stomach as the tube is guided into place.
Conclusion
A GJ tube is a very effective solution for patients whose stomachs cannot safely process food. By delivering nutrition straight to the intestines, it bypasses blockages and drastically lowers the risk of aspiration.
