Percutaneous endoscopic gastrostomy (PEG) describes the endoscopic formation
of a feeding gastrostomy. It negates the need for a laparotomy and general anaesthesia.
There has been a 20% increase year-on-year over the last decade in patients
registered to receive Home Enteral Tube Feeding (HETF) in the UK and these patients
are maintained on this regime for longer . At the end of 2002 there were
19,500 adult patients in the UK on HETF, an average of about one patient per
- the patient is fasted for 6 hours and sedated intravenously. The stomach
is then distended with air from an inserted endoscope. Using the light source
of the endoscope for guidance, the abdominal wall is then punctured externally
and an IV cannula passed through to the stomach. Externally, a long piece
of silk suture is then passed through the cannula, is grasped by the snare
of the endoscope, and both are removed via the mouth
- the free end of suture coming out of the patient's mouth is then tied to
a specialised tapered catheter. After lubrication, the catheter is drawn by
pulling on the abdominal wall free end of silk down into the stomach and through
to the anterior abdominal wall.
