About Gastrostomy Tubes (G-Tubes)

What is a gastrostomy tube (g-tube)?

A gastrostomy tube, also known as a g-tube or a feeding tube, helps children get the nutrition they need by providing calories, fluids and medicine. A g-tube may be needed when a child cannot eat and drink safely, or well enough, using his or her mouth.

Using a g-tube improves your child’s quality of life by allowing the body to stay properly fed and hydrated. If your child’s health improves, your doctor can remove the g-tube later on.

Why does my child need a g-tube?

A child may get a gastrostomy tube for a variety of reasons, most commonly because he or she:

  • Is unable to gain weight due to not consuming enough calories
  • Has trouble swallowing, eating, drinking or taking medicine
  • Breathes food or fluid into his or her lungs when swallowing
  • Has an esophagus that doesn’t function properly 
  • Needs more calories than he or she can ingest through his or her mouth

What can patients and families expect from g-tube placement?

G-tubes are placed by a pediatric surgeon who performs a surgery called a gastrostomy. Most of the time pediatric surgeons at Children’s Hospital Colorado use a minimally-invasively surgery technique called laparoscopy. This means that the surgeon uses small incisions instead of a large one and a small camera to see inside of your child’s belly during surgery. Kids who have minimally-invasive surgery heal faster due to the smaller scars and have less pain during recovery.

About the gastrostomy surgery:

  1. During surgery, the surgeon creates a small hole through the abdomen and into the stomach.
  2. Then, a gastrostomy tube made of silicone is placed into the stomach through the hole.
  3. Your child’s gastrostomy tube is the width of a chopstick and is held inside his or her stomach by a water-filled balloon or an internal disk. 
  4. Between eight to 12 hours after surgery, you can use the g-tube to feed your child. The stitches dissolve by themselves and do not need to be removed; the incision heals within one to two weeks. 

Types of gastrostomy tubes

Your pediatric surgeon will decide what type of g-tube is best for your child. There are two types of g-tubes: 

  • Skin level or “buttons” are the most common type of g-tube that we use at Children’s Colorado. They are low profile and not noticeable under normal clothing. 
  • Long tubes that hang outside the body are generally only recommended if the skin level g-tube isn’t a good match for your child. If your child does have a long tube put in, we may be able to switch it out for a skin level g-tube at a later date. 

How long does gastrostomy surgery take?

The surgery to place a g-tube usually lasts about an hour, but can vary in length.

How long will my child stay in the hospital?

Most children only spend one night in the hospital after a gastrostomy tube placement. Before leaving, your care team will make sure:

  • You know how to care for the g-tube and feed your child. 
  • The g-tube is working properly and your child is comfortable. 

Living with a g-tube

Pediatric surgeons at Children’s Colorado understand that you may be concerned about how your child will live once they have a g-tube placed. Rest assured knowing that the goal is to help your child have a better quality of life. Crawling on the floor, playing sports and participating in activities, like swimming, is okay and even encouraged in order for your child to have a healthy lifestyle.

If you have concerns or questions about your child’s g-tube, please contact one of our nurses at 720-777-6571.
