Nose feeding tubes hang out in front of your face all the time in plain sight, and require no surgery to put in. PEG tubes are hidden under your shirt until you want to hook up to it and use it, and require a very minor surgery to put in. Personally I think that given what he has been through that a 20 minute surgery is nothing. I also think that getting back out into the world as soon as possible is a healing process... I don't think I would do that with a big tube hanging off the front of my face while I was in the mall. I needed my tube for MANY months after the end of treatments. Having 4 inches of tube hanging out of my nose, irritating the inside of my nasal passages, and feeling it in the back of my throat all the time would be unacceptable. The PEG is too easy a choice. Nasal tubes are meant to be used for VERY short periods of time as a rule.
