Nick, a person’s general physical condition is usually a better indicator than age concerning how well surgery will go. I was 68 when I was advised to have my J pouch removed, but the surgeon I saw for a second opinion said he could only recommend an ileostomy rather than an internal pouch based on my age. I was in very good physical condition. Since I strongly did not want to get the bag, I researched my options online and decided to get a BCIR (similar to a K pouch). The surgery went very well and I now enjoy a very good quality of life. If you are in good physical condition, your age should not be a factor on how well surgery goes.
