John's PEG tube has a cap and when he wants to use it, he has to remove the cap and screw on and extension. It is attached in the stomach with a butterfly of some sort. When it comes out they will just turn it from the cap area. If you get one of these be sure to get replacement caps immediately. There are generic caps which fit the tops of syringes etc and they fit John's tube. Also we got a replacement attachment for feeding in case the original got lost. They were not happy about giving us these but did so.
John also just developed an infection under the skin surrounding the tube. He had to put warm moist compresses on it as it is draining around the tube. My brother is a surgeon and puts PEGS in. He said it is not uncommon to get and infection.
