Differences in Feeding Tubes

  1. As a nursing student, I still do not fully understand the differences between a PEG Tube, G Tube, J Tube and a GJ Tube. Why would someone need a PEG Tube over a G Tube? What are the differences? Same goes with a GJ Tube.
    Thanks in advance.

    Percutaneous Endoscopic Gastric (PEG) tubes and G Tubes are both interchangeable. They just mean that the tube lies gastric area or in the stomach. A PEJ tube or J tube is a tube that lies further down in the jejunum of the small intestine. People with GI motility problems or absorption problems may need one tube over another. Many physicians will prefer J Tubes on patients with problems like gastroparesis. If the gastroparesis is bad enough, some patients get the dual GJ tube which is a double lumen tube where one lumen lays in the stomach and one is in the jejunum - this allows for feedings via the J tube and decompression of the stomach via the G Tube.
