I had a J pouch for 30 years that had to be removed due to recurrent high grade dysplasia and a malignant polyp in the anal canal. The surgeon at a very well-known medical center gave me a second opinion and would only recommend an ileostomy, which I strongly did not want. The reason he gave was my age, which was 68. Fortunately I knew of two alternatives that do not require an external bag, and I got a BCIR. The surgery went very well and I have had no problems with my BCIR (which is similar to a K pouch). If you are in good physical condition, which I was, age should not prevent having a good result with a J pouch or one of the alternative internal pouches. Be sure to get a surgeon who has done many of the procedure you decide to have.
