What is percutaneous endoscopic gastrostomy (PEG)?

Percutaneous endoscopic gastrostomy (PEG) is a procedure designed to place a flexible feeding tube through the wall of the stomach so feeding can be performed via the tube, bypassing the mouth and esophagus. The tube allows nutrients as well as medicine to be administered directly to the stomach.

How is PEG performed?

Prior to the procedure, you'll receive a sedative via IV and the area where the incision will be made will be anesthetized. You'll also be given an antibiotic through your IV to prevent infection following the procedure. Once you're sedated and the incision area is numbed, Dr. Lai will insert an endoscope through your mouth and esophagus and into your stomach. A tiny lighted camera on the end of the endoscope will enable him to make a tiny incision through the skin of your abdomen directly into your stomach. Once the incision is made, the tube will be inserted and secured and a sterile dressing will be placed around the tube insertion site. Most procedures are performed on an outpatient basis, but some patients may require an overnight stay.

Why is the PEG procedure performed?

PEG is usually performed to aid patients who have significant difficulties swallowing, including patients who have had a stroke that impairs the ability to swallow food and drink. In some cases, feeding tubes may be used to help treat people with eating disorders or other conditions that prevent normal ingestion of food and liquids.

How long do the tubes remain in place?

PEG tubes may remain in place for a few months to several years. Over time, the tubes may break down or become clogged and must be changed. The tubes can be easily replaced without sedatives in most cases; in some cases, sedation and endoscopy may be required. If the tube becomes dislodged accidentally, call your doctor immediately for replacement.
