GJ Tube Exchange-Pediatric


GJ placement is a procedure in which a catheter is inserted into the stomach and then into the small bowel. This procedure is typically used to address the improper function of muscles of the gastrointestinal tract, aspiration, and excessive vomiting in children.

What is it?

GJ tube exchange occurs because the patient has vulnerable airways, is at risk of aspiration pneumonia, or has gastroesophageal reflux. It is a minimally invasive procedure that uses an image-guided technique to place a catheter into the stomach and then into the small bowel. The tube acts as a feeding tube and is used as an alternative to IV feeding.

How to prepare?

Individuals should not consume food twelve hours prior to the procedure and may need to avoid certain dietary supplements and medications.

What happens during the process?

During the procedure, the patient will be asked to lay down on a table. With the guidance of X-ray imaging, the doctor will place the tube into the gastrostomy (existing hole in the stomach) and then into the small bowel. Once the catheter is in the small bowel, the doctor will inflate a balloon to keep the catheter in place. Once secured, the patient will be ready to go home. 

What are the risks and potential complications?

Risks associated with GJ tube exchange include infection, bleeding, and exposure to radiation.
