This is an insertion of a feeding tube through the abdominal wall into the stomach during an upper endoscopy.  A small incision is made on the left side of the abdomen, and then a small, flexible, hollow tube (catheter) with a balloon or flared tip is inserted through the stomach.  PEG placement is also known as: gastrostomy tube insertion; g-tube insertion; stomach tube insertion; percutaneous endoscopic gastrostomy (PEG) tube insertion.

Gastrostomy tubes are inserted for various reasons. They may be needed temporarily or permanently. Gastrostomy tube insertion may be recommended for:

  • Birth defects of the mouth, esophagus, or stomach (esophageal atresia or tracheoesophageal fistula)
  • Patients who cannot swallow correctly
  • Malnourished patients who cannot take enough food by mouth to maintain their nutrition
  • Patients who continually aspirate when eating

PEG Placement Procedure Preparation

  • No food or liquids (this includes water) minimally 6 hours prior to the procedure.
  • You may also have diet and/or medication restrictions the week prior to the exam. Please refer to your physician for detailed instructions.
  • Plan to take the day off from work for the exam.
  • The procedure is performed with intravenous sedation. Patients are routinely admitted for observation and antibiotics.
  • Contact the physician and inform him or her of any special needs, medical conditions, latex allergy or current medications you are taking.
  • The GI Lab staff will attempt to contact you the evening before your procedure to answer any questions you may have.

Pre-PEG Placement Procedure Expectations

  • You may be expected to arrive 30 minutes prior to your scheduled exam time.
  • You may have an intravenous line placed, since the procedure is usually performed with intravenous sedation.
  • The procedure usually takes about 20-30 minutes.
  • During the exam, there is often a feeling of pressure in the abdominal area.
  • Your physician may give you medication to help you relax and better tolerate the exam.
  • During the procedure the physician may take biopsies (small tissue samples) or remove polyps (growths on the lining of the stomach).

Post-PEG Placement Procedure Expectations

  • After the procedure is completed you will recover for about 30 to 45 minutes.
  • You may experience a sore throat after the procedure.
  • Once you have met the discharge criteria, the physician will discuss with you the preliminary findings.
  • After the recovery period patients are able to start clear liquids and then advanced.
  • Diet and/or medication restrictions may be given to certain patients depending on the findings of the exam.
  • The stomach and abdomen will heal in 5 to 7 days. Moderate pain can be managed with medications. Feedings will start slowly with clear liquids and gradually be increased.

The following information will be reviewed with you:

  • How to care for the skin around the tube.
  • Signs and symptoms of infection.
