Hi. My dad has also been using a peg tube as his sole source of nutrition for about 14 months. His throat has been stretched about 5 times and 3 of those were unsuccessful. He seems to have a 2cm stricture in his esophagus due to radiation, so it will take quite a few more stretches before things are better. Anyway, for now he has just been switched to the new carnation vhc product and has gained 3 lbs in about 3.5 weeks, so it is a great product and something to look into. Before that he used ultra cal and boost plus and was able to maintain his weight but never gain any. Also,we did vital stim therapy that seemed to help him gain more control of his throat muscles in general and seems to be very helpful in head and neck cancer patients. Anyone wishing to talk or want more information is welcome to send me a message directly. God Bless! Christy
