Percutaneous endoscopic gastrostomy (PEG) is a type of feeding tube which is inserted through the skin of the abdomen into the stomach during an endoscopy. You may need a PEG if food, drink and medicines cannot reach your stomach (for example, if you can't swallow properly).
It can be put in via two methods: PEG or RIG. PEG stands for Percutaneous Endoscopic Gastrostomy - inserted via a telescope down the food pipe. RIG stands for Radiologically Inserted Gastrostomy - inserted using X-ray guidance after having barium placed inside the stomach.
