What questions do you have, my son has had one for the last five years. He got it when he was five years old. We use it at night to give him extra calories. It is connected to a pump that pumps formula like Two Cal over about seven hours. There are many different ways this can be done. We also used it to take vitamins and other meds that tasted bad. Worked really good for that when he was little. The surgery can be done a few ways too. I will let your doctor explain the procedure. Overall, I like having the ability to push more calories while he is asleep, Massey has complained at times, but that seems to be when the balloon has slightly deflated and fluid is leaking around the buttom. Milk-o-Mag seems to work great for the irritation. Hope this helps, if you have any other questions feel free to ask.
