I had to have my colon removed in April 2006 following a very severe flare up of Ulcerative Colitis. I was supposed to be having a reversal surgery after about 3 months but then developed insulin dependent diabetes. This was caused by long term, high dose, steroids which I had prior to the surgery. Because of various other problems, I decided late last year that I would never have the reversal surgery and I made the decision to stick with my bag. I find the bag has made my life so much easier - no more dashing about trying to find restrooms and the pain that goes with it. About 11 inches of rectum/anus had been left after the first surgery which would be needed for reversal surgery. Once the decision had been made that I would not have a reversal, my surgeon recommended that this final 11 inches of plumbing should be removed as the colitis was still active in that portion of my body. I had my rectum and anus removed in April 2009 and I can't begin to tell you how much better I feel for it.
Of course, what you have to bear in mind is that I am now 50 years old, far different to a young 18 year old. It would be wrong of me to profer an opinion on whether she should have it done as she will have different reasoning criteria than I had. However, for me, it is the best decision and one that allows me to live as normal a life as possible.
Sadly, the diabetes has wreaked havoc on my body and I also suffer from diabetic neuropathy - a painful condition in my feet. It is nerve damage caused by high dose steroids and immuno suppressants which gave me artificially high blood sugars, despite the best efforts of me and my surgical/medical team to control my levels.
