G-Tube Program

The G-Tube Program provides care and support to children who are less than 18 years old that require, or already have a Gastrostomy or GastroJejunostomy tube. The G-Tube team consists of a nurse practitioner and two G-Tube resource nurses who work closely with a paediatrician and the interventional radiologists in the IGT department.  

What is a Gastrostomy (G) Tube? 

A G-Tube is a feeding device that is inserted into the stomach through the abdominal wall. It provides a way of feeding a child who cannot feed by mouth.  A G-Tube can deliver:  

    • Complete or supplementary nutrition (i.e. formula, expressed breast milk) and/or
    • Fluids (i.e. water, juice, Pedialyte™) and/or
    • Blended diet and/or
    • Medication

What is a GastroJejunostomy (GJ) Tube?

A GJ-Tube is a feeding device that is inserted through the abdominal wall, into the stomach, past the outlet from the stomach (pylorus), and into the small bowel (jejunum). It provides a child with:

    • Complete or supplementary nutrition (i.e. formula, expressed breast milk) and/or
    • Fluids (i.e. water, juice, Pedialyte™) and/or
    • Medication

How are G or GJ Tubes inserted?

G and GJ-Tubes are usually placed in the IGT suites by an interventional radiologist under a general anaesthetic. Occasionally, a patient may only require a light sedation and local anaesthetic. For children in which a radiologically placed tube cannot be performed, tubes are inserted in the operating room. Sometimes, if a patient is undergoing another surgical procedure, the G-Tube may be inserted surgically at the same time, under the same general anaesthetic.

Benefits of a G/GJ Tube for Patients

    • Safer than a nasogastric tube.
    • Provides nutrition into the stomach or jejunum which is preferred over providing nutrition directly into the blood, which is also known as Total Parental Nutrition (TPN).
    • Supports nutrition and hydration in times of health and sickness.
    • Supports a strong immune system.
    • Supports growth and brain development.
    • Helps with giving medicine.
    • Helps release gas from the stomach and makes children more comfortable.

G/GJ Tube Caregiver Class

The G-Tube Program offers group education to families during the G-Tube consultation. The G/GJ-Tube Caregiver class is held every Wednesday morning and occasional Monday mornings. It is located in the Gastroenterology Clinic (4th floor, Black Wing Elevators) from 9 a.m.  - 12:30 p.m.. This is not a drop in class; you must contact the G-Tube team and schedule a date.

The class provides an overview of the procedure, benefits and risks of G/GJ-Tube insertion. It also educates families on how to care for the tube, and manage issues that might arise, such as tube blockage, accidental dislodgement, breakage, stoma infection, granulation tissue, leakage and skin sensitivity.
