If you previously had success with exercises, I would suggest trying them again. Never know, maybe you will be successful. Its definitely worth a try.
Briefly, here's what I know about feeding tubes. There are 3 types of feeding tubes, the PEG tube, J/G tube and the Mickey button. From what Ive heard, the Mickey button is the easiest one to use and much less bulky than the other 2 types. The PEG tube goes directly into the stomach. The J/G tube has the G side going into the stomach like the PEG tube. Its also has another port which goes into the intestine. The PEG tube lasts the longest of all the types. Ive had both the PEG tube and the J/G tube. The J/G tube (for me) needs to be replaced every 3 or 4 months. Some lucky patients are able to make their J/G tube last longer than mine last.
Good luck!
PS... Here is a link with tons of info about feeding tubes and tube feedings from the main OCF pages.
