After Buzz had his surgery, an NG tube was placed, and was used for several days, but kept slipping out, requiring trips down to x-ray each time. After the third time, Buzz refused to let them put it back. Before beginning radiation/chemo, he had a PEG placed and says that it was a life saver!
Having had both the NG and the PEG, he stands by his preference for the PEG.
Good luck to you!
