Is there a difference between peg/j tube and g/j tube ? is there an abbreviation difference related to the way it is inserted or held in place?

Peg tube/j tube: Hello, these are various methods of enteral feeding in a pt with different indications. Peg-tube( per-cutaneous endoscopic gastrostomy tube) is usually placed by a GI physician, into the stomach by performing a gastroscopy. A g-tube is also the same procedure but is performed by a surgeon without a possible gastroscopy. J- tube indicates a feeding tube placed in the jejunum. Hope this helps.
