Percutaneous Endoscopic Gastrostomy Insertion


Percutaneous endoscopic gastrostomy (PEG) insertion is a procedure to place a soft, plastic feeding tube into your stomach. You may need a PEG tube if you cannot get enough nutrition eating your food. Liquid food can be given through the tube to give your body the nutrition it needs. The tube may also be used to remove air and fluid from your stomach.


Before your procedure:

  • Informed consent is a legal document that explains the tests, treatments, or procedures that you may need. Informed consent means you understand what will be done and can make decisions about what you want. You give your permission when you sign the consent form. You can have someone sign this form for you if you are not able to sign it. You have the right to understand your medical care in words you know. Before you sign the consent form, understand the risks and benefits of what will be done. Make sure all your questions are answered.
  • An IV is a small tube placed in your vein that is used to give you medicine or liquids.
  • Local anesthesia is a shot of medicine put into your abdomen. It is used to numb the area and dull the pain. You may still feel pressure or pushing during the procedure. You will also be given medicine in your IV to keep you calm and relaxed.

During your procedure:

  • Your healthcare provider will insert the endoscope through your mouth, down your esophagus, and into your stomach. The light on the end of the endoscope may be seen through your abdomen. The light will help your healthcare provider find the best place to insert the PEG tube. He may inject air into your stomach so he can see clearly.
  • Your healthcare provider will make a small incision in your abdomen and insert a catheter with a wire through the opening and into your stomach. He will guide the wire up through the endoscope and into your mouth. The PEG tube will be attached to the wire and pulled down into your stomach. Your healthcare provider will bring one end of the PEG tube out through the opening in your abdomen. The other end of the PEG will stay in your stomach and will be held in place with a piece of plastic or small inflated balloon. This will prevent it from coming out through the opening in your abdomen (stoma).
  • Once the PEG tube is in the right place, the endoscope and wire will be removed. If your healthcare provider cannot use an endoscope, he will place the PEG tube directly into your stomach through the incision on your abdomen. He will use an ultrasound to find the right place to put the PEG tube in your stomach.

After your procedure:

You will be taken to a room to rest until you are fully awake. You will be monitored closely for any problems. Do not get out of bed until your healthcare provider says it is okay. You will then be able to go home or be taken to your hospital room.


  • The endoscope may cause damage or bleeding in your esophagus, stomach, or abdomen. During or after the procedure, liquid from your stomach may get into your lungs and cause an infection. Your stoma and skin around it may be bruised and painful. Sores may form in the skin around your stoma, and tissue may grow over the PEG tube.
  • The end of the PEG tube in your stomach may move out of place. Your PEG tube may become blocked and it may crack, break, or leak. Your stomach may not empty into your intestines correctly. A fistula (abnormal tissue opening) may form between your skin and stomach or intestines. Your stoma may become infected. The infection may spread to other areas of your body and become life-threatening.
