Percutaneous Endoscopic Gastrostomy: Before Your Procedure

What is a percutaneous endoscopic gastrostomy?

Percutaneous endoscopic gastrostomy is a procedure to make an opening between the skin of your belly and your stomach. The doctor will put a thin tube called a gastrostomy tube into your stomach through the opening. This tube is sometimes called a G-tube, a PEG tube, or a feeding tube. The tube can put liquid nutrition, fluid, and medicines directly into your stomach. The tube also may be used to drain liquid or air from the stomach.

You will get medicine to numb the back of your throat. You also will get medicine to make you sleep or feel relaxed. The medicine also prevents pain during the procedure. The doctor will put a thin, lighted tube that bends (called an endoscope, or scope) into your mouth. He or she will move the scope gently down your throat. The scope will have a camera on it. The doctor will look at a monitor (like a TV set or a computer screen) as he or she moves the scope into your stomach. The doctor will send puffs of air through the scope. This inflates your stomach. It helps the doctor see where to place the feeding tube.

The doctor will make a small cut in your belly. The cut is called an incision. The doctor will put the feeding tube into your mouth. Then he or she will guide the tube down your throat into your stomach. The doctor will pull one end of the feeding tube out of your belly through the incision. This end of the feeding tube will stay outside your body. The other end will stay in your stomach. The doctor may use stitches to close the incision around the feeding tube.

You will go home the same day as your procedure. Before you go home, your doctor or nurse will teach you how to use and care for your feeding tube.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

What happens before the procedure?

Preparing for the procedure

  • Understand exactly what procedure is planned, along with the risks, benefits, and other options.
  • Tell your doctors ALL the medicines and natural health products you take. Some of these can increase the risk of bleeding or interact with anesthesia.
  • If you take aspirin or some other blood thinner, ask your doctor if you should stop taking it before your procedure. Make sure that you understand exactly what your doctor wants you to do. These medicines increase the risk of bleeding.
  • Your doctor will tell you which medicines to take or stop before your procedure. You may need to stop taking certain medicines a week or more before the procedure. So talk to your doctor as soon as you can.
  • If you have an advance care plan, let your doctor know. Bring a copy to the hospital. If you don't have one, you may want to prepare one. It lets your doctor and loved ones know your health care wishes. Doctors advise that everyone prepare these papers before any type of surgery or procedure.
