I agree with Brian. You must remember that the site of the peg tube is not a sterile site. The risk of infection is much less than say a port. John is very happy he had a peg tube. His doctor complimented us on the fact that his nourishment level (per blood tests) during chemo and radiation were normal. She indicated that this was important to heal. John's weight dramatically plunged before the tube. After the tube, he gained to near normal weight.
Good luck.
