Thanks for clarification and support I was completely healthy before diagnosis, I hope that I won't have any issues with pouch. My father didn't have any GI polyps since surgeries (more than 30 years). Internist who performed colonoscopy and gastroscopy said it is a good sign for me to not have any polyps anywhere except on my colon and rectum. I had 3 polyps on rectum and she said that there is a possibility of having my rectum left in place with regular checkups, but if once arises a need to remove my rectum that surgery is going to be far more serious than removing rectum now. It's up to the surgeon to decide whether to remove or not rectum.
I have another question: What happens when j-pouch fails or it has polyps? You get it removed and created an ileostomy?
All the best,
Sorry about your Grandma honey, Glad your dad is well
Sometimes when the J-pouch fails, some people get redos. Redos can be an option depending on what the case is. Some people on here have talked about their experience with getting polyps removed. I have talked to some FAP people on here personally and they are doing fine with their pouch with no polyps, I cannot say that for all cases though.
I have a personal friend on here, his name is Rev Lenny and he has FAP, I am sure he would be more than happy to answer your questions and make you feel safer about J-pouch surgery. i would recommend to send him a private message, you two are a lot alike. His name is Rev Lenny.
When you send Rev Lenny a private message, just let me know so I can tell him personally to read it and message you back.
I wish you luck and many blessings on your surgery
