"Occasionally contrast will be injected via the PEG to determine its position, a so-called PEGogram."
"Percutaneous endoscopic gastrostomy (PEG) is a procedure where a flexible feeding tube (commonly known as a PEG tube) is inserted through the abdominal wall and into the stomach via endoscopy. Alternatively a tube can be placed under radiological guidance, known as a radiologically inserted gastrostomy (RIG) or percutaneous radiological gastrostomy (PRG)."
"A PEG tube permits nutrition, fluids and/or medications to be placed directly into the stomach, bypassing the mouth and oesophagus. This is typically performed when a patient is either unable to, or it is unsafe for them to, consume nutrition orally (e.g. in patients with swallowing issues or head and neck malignancies)."
