Percutaneous endoscopic gastrostomy (PEG) is a procedure to place a tube through the belly wall and into the stomach.
Reasons for Procedure
A PEG gives you a different way to get nutrients. It may be needed to:
- Feed a person who has a hard time sucking or swallowing, or who is otherwise unable to eat
- Drain the stomach of a buildup of fluids
Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems such as:
- Problems with the PEG tube
- Aspiration—accidental sucking into the airways of fluid, food, or any foreign material
- Damage to other organs
- Inflammation of the belly lining
- Irritation of the skin near the tube
- An abnormal opening between 2 structures—fistula
Your chances of problems are higher for:
What to Expect
Prior to Procedure
You may have:
Leading up to your procedure:
- Don't eat or drink for at least 8 hours before the procedure.
- Arrange for a ride.
- Talk to your doctor about the medicines you take. You may be asked to stop taking some medicines up to 1 week in advance.
- Local anesthesia—usually a lidocaine spray to numb the throat
- Pain medicine—usually given with an IV
- To help you relax, you may be given a sedative
Description of the Procedure
An endoscope will be inserted through your mouth and into your stomach. The camera will send images to a video monitor. This will help find the right place for the PEG tube.
A needle will be placed through the belly wall and into the stomach. A thin wire will be passed from the outside of the body, through a needle, and into the stomach. This wire will be grasped with a snare in the belly and pulled out through the mouth. There will be a thin wire from the front of the belly, going into the stomach, and continuing up and out of the mouth. The PEG feeding tube will then be attached to this wire. The wire will be pulled back out from the belly. This will pull the PEG tube down into the body.
A small cut will be made in the belly. The tube will be pulled until the tip comes out from this cut. A soft, round bumper will be attached to the ends of the PEG tube. It will keep the tube secure. Germ-free gauze will be placed around the wound. The PEG tube will be taped to the belly.
