Definition of Gastrostomy, percutaneous endoscopic (PEG)
Gastrostomy, percutaneous endoscopic (PEG ) definition - medical term
A surgical procedure for
placing a feeding tube without having to perform an open laparotomy (operation on
the abdomen). The aim of PEG is to feed those who cannot swallow. PEG may be done
by a surgeon, otolaryngologist (ENT specialist) or gastroenterologist (GI specialist).
It is done in a. hospital or outpatient surgical facility. Local anesthesia (usually
lidocaine or another spray) is used to anesthetize the throat. An endoscope (a flexible,
lighted instrument) is passed through the mouth, throat and esophagus to the stomach.
The surgeon then makes a small incision (cut) in the skin of the abdomen and pushes
an intravenous cannula (an IV tube) through the skin into the stomach and sutures
(ties) it in place. The patient can usually go home the same day or the next morning.
Possible complications include wound infection (as in any kind of surgery) and dislodging
or malfunction of the tube. Percutaneous endoscopic gastrostomy may be a mouthful
(as a term) but it describes the procedure accurately. A gastrostomy (a surgical
opening into the stomach) is made percutaneously (through the skin) using an endoscope
to put the feeding tube in place. PEG takes less time, carries less risk and costs
less than a classic surgical gastrostomy which requires opening the abdomen.
