Gastrostomy Tube (G-Tube)

What is a G-tube?

  • A gastrostomy tube (also called a G-tube) is a tube inserted through the abdomen that delivers nutrition directly to the stomach.
  • It's one of the ways doctors can make sure patients with trouble eating get the fluid and calories they need.
  • Fortunately, a gastrostomy is a common procedure that takes only about 30 to 45 minutes.
  • After spending 1 or 2 days in the hospital, patients who had a gastrostomy can get back to their normal activities.

There are three methods for inserting a G-tube:

the percutaneous (through the skin) endoscopic gastrostomy (PEG) laparoscopic technique & open surgical procedure The laparoscopic technique may be used along with the PEG approach or in conjunction with another intestinal operation performed at the same time. All methods are fairly simple and typically take about 30 to 45 minutes to perform.

1- The PEG procedure, which is the most common technique, uses an endoscope (a thin, flexible tube with a tiny camera and light at the tip) inserted through the mouth and into the stomach to guide the doctor's positioning of the G-tube. The doctor use a device to prevent complications, it is a plastic tube inserted into the throat and the windpipe to help a patient breathe during surgery. The tube is connected to a ventilator that pushes air in and out of the lungs.

2- Laparascopic Technique; it is done by making several small incisions in the abdomen and inserting a tiny telescope that helps surgeons see the stomach and surrounding organs. The same precautions described above — the nasogastric tube and endotracheal tube — are used. Stitches and pressure from a tiny balloon are used to keep the stomach in place against the abdominal wall.

3- Open Surgery; is an excellent approach for placing a gastrostomy tube, but is usually reserved for cases where the patient’s anatomy won't allow for a PEG; if there is scar tissue from a previous surgery, procedure, or illness; or when the patient requires another surgical procedure at the same time. Antibiotics may continue for 24 to 48 hours after the procedure to prevent infection.


  • Patient will probably remain in the hospital for 1 to 2 days following the gastrostomy.
  • Gastrostomy is generally a very well tolerated, often life-saving procedure.
  • Once the tube is in place, kids without other serious medical issues can get back to their normal activities.

Risks and Complications:

All three types of gastrostomy procedures are considered safe and effective. However, as with any surgical procedure, there are some risks, including: Anesthesia, bleeding, Allergic Reaction &Potential Complications at the Tube Site.
