Percutaneous endoscopic gastrostomy

A.Prof Frank Gaillard and Dr Ian Bickle et al.

Percutaneous endoscopic gastrostomy (PEG) is a procedure where a is a flexible feeding tube (commonly known as a PEG tube) is inserted through the abdominal wall and into the stomach. This may be placed under endoscopic or radiological guidance, in the latter, the procedure may be known as a percutaneous radiological gastrostomy (PRG) or radiologically inserted gastrostomy (RIG).

A PEG tube permits nutrition, fluids and/or medications to be placed directly into the stomach, bypassing the mouth and esophagus. This is typically performed when a patient is either unable to, or it is unsafe for them to, consume nutrition orally.

On occasion it is necessary to image for complications of PEG tubes - either immediately after insertion or when long standing. The typical clinical problem relates to concerns over displacement, including buried bumper syndrome.
