I also have FAP and had a J pouch for 30 years before it had to be removed due to a malignant polyp and recurrent high grade dysplasia in the anal canal. I got a second opinion on my condition and carefully researched my options. In my case, I strongly did not want an ileostomy and opted to get a BCIR. I have now had it for just over five years and it has given me an excellent quality of life. I have no regrets whatsoever for the decision I made. The surgery to remove my J pouch was challenging due to the presence of numerous dense adhesions from earlier surgery. I was in the hospital for the customary 21 days and was able to do almost anything I wanted three months after surgery. The important things to remember are to maintain a positive attitude and to start walking soon after surgery. Since I did not opt for an ileostomy, I am unable to comment on life with one. Recovery from ileostomy surgery should be similar to the surgery I had. I wish you the best with your upcoming surgery.
