Feeding Tube Insertion

A gastrostomy is a direct opening through your abdominal wall into your stomach. A gastrostomy tube (sometimes called PEG tube) is passed through this opening. This allows you to get food and medicine without having to swallow. It's more comfortable and easier to use than a tube from the nose to the stomach. Gastrostomy tubes are used in temporary or permanent conditions where there is difficulty swallowing. This includes stroke, cancer of the mouth, throat, or esophagus, or radiation to the chest.

The most common way this type of feeding tube is inserted is during an endoscopy. This is a test where a flexible tube with video camera is placed through your mouth into your stomach. You are usually sedated with IV medicine for comfort. Once the feeding tube is placed, the scope is removed.

Feeding tubes generally last 6 to 12 months before they need to be replaced. Replacement is usually easier than the initial insertion, since the opening is already there.

Home care

The following will help you care for yourself at home:

During the first weeks after insertion, do the following:

  • Clean the area around the wound daily, .apply a topical antibiotic ointment only if recommended by your provider. Cover the tube at the insertion site with gauze. Make sure the gauze is over the skin and tube, not between.

  • Watch for redness, swelling, or pus coming from the opening in the skin.

  • Watch for leakage around the tube and report this to your healthcare provider.

  • If the tube falls out, it must be put back in within 24 hours or the wound will close up.

Start feedings as instructed:

  • Wash your hands with soap and water before preparing the formula or touching the feeding tube.

  • The tube is narrow, so use only commercial feeding formulas. This will help make sure the tube will not get clogged. These formulas are designed to provide all the protein, carbohydrates, vitamins, and minerals needed. Follow your healthcare provider’s advice (or the registered dietitian or nurse who is working with you) about the number of feedings to give each day.

  • Flush the tube with clear water before and after feedings or after medicine has been given through the tube. This is very important. Otherwise the tube can become blocked.

  • When feeding, you should be upright or reclining at not less than 30 degrees to reduce the risk of the feeding solution draining improperly and causing aspiration into the lungs. Stay in this position for at least 30 minutes after the feeding.

  • Infuse food slowly. It may take more than 1 hour for 1 feeding session.

Other guidelines:

  • If the tube becomes blocked, flush with a syringe full of water.

  • If you feel bloated after feeding, remove the cap from the end of the tube so that extra air in the stomach can flow out. Cough to help remove the extra air.

  • Oral and dental care is needed, even if you are not taking any food or liquids by mouth. Brush your teeth and gums daily. Keep the lips moist with a lip balm or petroleum jelly.
