In brief: Ways to feed body
Tpn stands for total parenteral nutrition.
All nutrition is obtained from a bag of liquid nutrients and infused through an iv. A peg is a tube placed into the stomach from outside the abdomen, which is used to feed the stomach with liquid nutrition. A g tube is similar to a peg tube, but it is surgically placed while a peg is endoscopically placed.

In brief: Different things
Tpn=total parenteral nutrition; nutrition is given intravenously, usually through a central venous access device (e.
g. Central line or picc). A g-tube (or gastrostomy tube) is a flexible tube that goes through the abdominal wall directly into the stomach. A peg is a type of g-tube that is placed by an endoscopist (surgeon or GI doctor); a surgeon can also perform an operation to place a g-tube.

In brief: Nutrition
Tpn = total parenteral nutrition, which is IV feeding.
This is used to provide feeding while bypassing the digestive system. A g-tube and a peg tube are both tubes inserted directly into the stomach through the abdominal wall to introduce nutrients directly into the stomach.

In brief: Nutrition
It's a mixture of vitamins, fats and carbohydrates given in a liquid form intravenously through a large vein of the body to people who are unable to digest food through the stomach. Both a peg and a gtube administer a liquid form of food directly to the stomach, in those who aren't able to swallow. A peg is placed by a GI doc while a gtube is placed by a surgeon.

In brief: Lots
Tpn, or total parenteral nutrition, is given through a vein.
It is considered risky if your gut is working (infections and wacky electrolytes can result). A peg (or percutaneous endoscopic gastrostomy, aka g-tube) is where we place a flexible rubber tube about the caliber of a drinking straw straight through your skin in your belly and into your stomach. This allows us to feed you into your gut.
