Welcome back, Frances. It is nice to see you post again. I have no answers for you EXCEPT about the PEG. I made an appointment to have mine removed and when I got there, was informed that I had failed to get the okay of the doctor. Told them "my tube, my body, my decision" etc., and they pulled it, telling me that if I had to have it put back in, it would not be any problem. So who knows? I know after not using mine for just a couple of weeks, I was most anxious to be rid of it. I am glad you are feeling so well, and hope you can get more information so you can wade through all the options with some assurance. I will vote for the scar tissue option!
