Gastrostomy

A surgical opening into the stomach. This opening may be used for feeding usually via a feeding tube called a gastrostomy tube. This can also be done by percutaneous endoscopic gastrostomy (PEG). PEG is a surgical procedure for placing a feeding tube but does not necessitate doing an open laparotomy (operation on the abdomen). The aim of PEG (as with any gastrostomy) 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, when feasible, takes less time, carries less risk and costs less than a classic surgical gastrostomy which requires opening the abdomen.

Establishment of a new opening into the stomach. [gastro- + G. stoma, mouth]

- percutaneous endoscopic g. a g. performed without opening the abdominal cavity; usually involves gastroscopy, insufflation of the stomach, puncture of stomach and abdominal wall, followed by placement of a special tube.

n.

a surgical procedure in which an opening is made into the stomach from the outside. It is usually performed to allow food and fluid to be poured directly into the stomach when swallowing is impossible because of disease or obstruction of the oesophagus. Sometimes it is used temporarily after operations on the oesophagus, until healing has occurred. Formerly a gastrostomy was always performed surgically, but it can now be done using an endoscope (percutaneous endoscopic gastrostomy) or by direct puncture under radiological guidance.
