My FAP was also discovered by a colonoscopy and I was told 33 years ago that surgery was necessary to save my life. I had one of the early J pouch operations and am now alive and healthy and enjoying my four grandchildren. Surgical techniques have improved greatly and properly administered pain medications make pain less of an issue. J pouch surgery has a high rate of success and patient satisfaction and is the procedure of choice for UC and FAP. Be sure that your surgeon has lots of experience and a good track record in performing this surgery. Two alternative procedures, the K pouch and closely related BCIR also avoid the need to have the bag, and are now most commonly used for those having problems with their J pouch or ileostomy. Lots of information about all of the surgical options plus FAP is available on the internet. I am hoping that your doctor discovered your FAP before any of the polyps became malignant and wish you the best! Sounds like you have a great family to support you in these challenging times.
