I have started keeping the Y extender tube in and then tucking it in a U shape into the waistband of my underwear. Works really well. I had tried pinning it but it always ended up pulling on me as I moved or twisted.

The first couple weeks when I had to keep antibiotic ointment on the stoma, my wife sewed me a shift top with no sleeves (out of an old T shirt) just an elastic top that I wore across my chest while the rest of it prevented the antibiotic ointment from staining my shirts or regular T-shirts. The ACE bandage sounds okay but it was really hot here in the summer and I got a rash if I firmly covered the PEG with any bandages of any type. Glad I did not have to deal with this the first time around.
